Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0031] Figure 1This is a flow chart of an automatic selection method for pipe supports and hangers provided according to an embodiment of the present invention. This embodiment can be applied to pipe supports and hangers. In the case of selecting supports and hangers according to the pipe building model, this method can be executed by an automatic selection device for pipe supports and hangers. The automatic selection device for pipe supports and hangers can be implemented in the form of hardware and / or software. The automatic selection device for pipe supports and hangers can be configured in an electronic device such as a computer. Figure 1 As shown, the method includes:

[0032] Step 110: Obtain design parameters of the pipeline, and perform data analysis based on the design parameters to determine target design parameters that affect the layout of supports and hangers.

[0033] The design parameters of the pipeline can be obtained from the design standards or specifications. The design parameters of the pipeline can include many aspects of information. For example, the design parameters of the pipeline include but are not limited to the size, material, working pressure, temperature, medium properties, structural form, support method, and the environmental information that can be supported around the pipeline support bracket. The obtained pipeline design parameters can be pre-processed to ensure the accuracy of the input pipeline characteristics and working environment conditions information, and to eliminate duplicate and invalid data. During data pre-processing, data from different sources can be uniformly formatted for subsequent processing and analysis.

[0034] When performing data analysis, the correlation between pipeline parameters and support and hanger parameters can be considered. For example, the temperature of the pipeline will affect the high temperature resistance of the support and hanger. For another example, the material of the pipeline will affect the material of the support and hanger. Based on the correlation between pipeline parameters and support and hanger parameters, the target design parameters that affect the support and hanger layout can be determined.

[0035] Specifically, in an optional implementation manner of an embodiment of the present invention, data analysis is performed based on the design parameters to determine the target design parameters that affect the support and hanger layout, including: parameter association matching of the design parameters with the support and hanger selection parameters to determine the target design parameters that affect the support and hanger layout; wherein the target design parameters include: pipeline size, material, working pressure, temperature, medium properties and environmental information.

[0036] The design and operation parameters of the pipeline are the basis for determining the design of the supports and hangers, and directly affect the selection, arrangement and load-bearing capacity of the supports and hangers. For example, the diameter and wall thickness of the pipeline affect the weight of the pipeline. The weight of the pipeline is related to the support performance of the supports and hangers. The length of the pipeline section is related to the spacing and number of supports and hangers. Pipeline materials include carbon steel, stainless steel, aluminum, plastic, copper, and alloys. Different pipeline materials have different mechanical properties (such as density, tensile strength, elastic modulus). The pipeline material is related to the load-bearing capacity, yield strength and tensile strength of the pipeline supports and hangers. Pipeline supports and hangers need to adapt to the requirements of pipeline materials to achieve the support effect. The type of conveying medium inside the pipeline (such as water, oil, steam, chemicals, etc.), its density and physical and chemical properties (such as corrosiveness, temperature, etc.) affect the weight of the pipeline and have requirements for the corrosion resistance and temperature of the supports and hangers. The working temperature range that the pipeline is subjected to directly affects the thermal expansion and contraction compensation capacity of the supports and hangers. The pressure level in the pipeline affects the stress distribution of the pipeline and indirectly affects the design requirements of the supports and hangers. The normal operating pressure inside the pipeline is used to evaluate the stress of the pipeline and the design of the supports and hangers. The supports and hangers must be able to withstand the load of the pipeline under the maximum pressure exceeding the normal working conditions. Therefore, based on the above relationship, the target design parameters that affect the layout of the supports and hangers can be determined.

[0037] Step 120: Perform pipeline stress analysis based on target design parameters to determine stresses at different locations of the pipeline.

[0038] The pipeline load directly affects the design of the supports and hangers. In the embodiment of the present invention, finite element analysis or other calculation tools can be used to evaluate the stress, deformation and vibration of the pipeline under different working conditions to determine the number, layout and type of supports and hangers. Stress analysis of the entire factory pipeline can be performed to select pipeline supports and hangers of different support forms at different locations of the pipeline.

[0039] For pipeline stress analysis, pipeline stress analysis software (such as CAESAR II, AutoPIPE, ROHR2, etc.) can also be used to simulate the stress distribution of the pipeline system under different working conditions to assist in the arrangement of supports and hangers. Through stress analysis software, the displacement, stress distribution and load of the pipeline under different working conditions can be intuitively understood, so as to more accurately determine the location and type of supports and hangers.

[0040] In an optional implementation of an embodiment of the present invention, a pipeline stress analysis is performed according to the target design parameters to determine the stress at different positions of the pipeline, including: performing a pipeline static analysis and a dynamic analysis according to the target design parameters to determine the stress at different positions of the pipeline; wherein the static analysis includes a primary stress analysis and a secondary stress analysis; the primary stress is caused by the weight of the pipeline itself, the weight of the medium, the insulation layer, and the internal pressure; the secondary stress is caused by the temperature and the end point displacement; the dynamic analysis includes: stress caused by vibration, earthquake, water hammer and impact load of the dynamic equipment in the environmental information.

[0041] Primary stress is the stress generated by pressure, gravity and other external loads. It is the stress required to balance the external load and increases with the increase of external load. The characteristic of primary stress is that it has no self-limitation, that is, when the plastic zone in the pipeline expands to the limit state and becomes a geometrically variable structure, even if the external load no longer increases, the pipeline will still produce unrestricted plastic flow until it is destroyed.

[0042] Secondary stress is the stress generated by displacement loads such as thermal expansion, contraction, and end point displacement. It is not directly balanced with external forces, but is the stress necessary to meet the displacement constraint conditions or the continuous requirements of the pipeline's own deformation. The characteristic of secondary stress is that it is self-limiting, that is, local yielding or a small amount of deformation can satisfy the displacement constraint conditions or the continuous requirements of its own deformation, so that the deformation will no longer continue to increase. Generally speaking, as long as there is no repeated loading, secondary stress will not cause pipeline damage. In other words, secondary stress mainly causes fatigue damage. It should be pointed out that when the displacement load is extremely large, local yielding or a small amount of deformation is not enough to satisfy the displacement constraint conditions or the continuous requirements of its own deformation, the pipeline may also be damaged during a single loading process.

[0043] The weight of the pipeline itself is determined by the material, diameter and thickness of the pipeline. The weight of the medium is determined by the volume, density, material and thickness of the medium in the pipeline. Temperature changes will cause changes in the length of the pipeline, and the supports and hangers need to allow sufficient expansion and contraction space for the pipeline. The vibration generated by the flow of the medium in the pipeline or the vibration caused by external mechanical equipment affects the seismic or vibration reduction design of the supports and hangers. When starting, shutting down or when water hammer occurs, the pipeline will generate instantaneous impact force, which affects the impact resistance requirements of the supports and hangers.

[0044] The expansion or contraction of the pipeline due to temperature changes will cause thermal stress in the pipeline. The weight of the pipeline and the weight of the medium acting on the support and hanger will cause gravity stress. The pressure of the medium inside the pipeline will cause stress on the pipe wall, especially high-pressure pipelines need special attention. Environmental factors such as wind loads and seismic loads will also bring stress to the pipeline system. Fluid vibration, pump impact loads, etc. may cause local vibration stress.

[0045] In pipeline stress analysis, there are key locations where stress is concentrated, which is particularly important for the selection and arrangement of supports and hangers. When conducting pipeline stress analysis, the locations to be analyzed include: pipeline elbows, pipeline tees, pipeline bends, long straight pipe sections, near heavy equipment, areas where the temperature and pressure change trends are greater than the set values, and cantilever pipe sections.

[0046] At pipe elbows, pipe tees, and pipe bends, the turning or diversion of the pipe will produce large bending stress and shear stress, so suitable supports and hangers are needed for support. Long-distance pipes are prone to large axial stress due to thermal expansion, so suitable supports and hangers are needed to release thermal expansion. Concentrated loads will be generated near heavy equipment such as valves and pumps, and supports and hangers should be strengthened. Places with large temperature or pressure changes are prone to stress concentration, and appropriate support is required to reduce stress. For cantilever pipe sections (such as branches leading from the main pipeline), since the length of the branch may be short, the suspended part of the pipe may be subjected to a large bending moment, so the supports and hangers need to be reinforced.

[0047] Step 130: Determine the type of support bracket at the corresponding position according to the stress at each position of the pipeline.

[0048] Different types of supports and hangers have different responses to displacement and force. Support and hanger types include but are not limited to: fixed supports, sliding supports, guide supports, spring supports, limit supports, hangers, seismic supports, rolling supports, lateral supports, and vibration-damping supports.

[0049] Fixed brackets are used to fix the position of pipelines and limit the displacement and rotation of pipelines. Fixed brackets are suitable for use when there is no obvious thermal expansion or displacement of pipelines. Fixed brackets are arranged at the fixed ends of pipelines, key turning points, equipment connections (such as pumps and valves), etc., mainly used to control the displacement and thermal expansion direction of pipelines. Too many or too few fixed brackets will cause stress concentration problems. Fixed brackets are generally set at the starting point, end point and branch point of each large system.

[0050] Sliding brackets allow the pipe to move freely in a certain direction. Sliding brackets are suitable for working conditions with large thermal expansion, commonly seen in steam pipes or high-temperature medium pipes, to avoid excessive deformation due to thermal stress.

[0051] Guide brackets restrict the displacement of the pipeline in one direction, but allow the pipeline to move freely in another direction. Guide brackets are suitable for long straight pipelines to prevent lateral displacement. Guide brackets are used to control the lateral displacement of the pipeline and ensure that the thermal expansion of the pipeline is freely released in the design direction.

[0052] For sliding brackets and guide brackets, the expansion direction and displacement direction of the pipeline must be considered to ensure that the bracket can freely release the thermal expansion displacement of the pipeline.

[0053] Spring brackets are used to absorb the thermal expansion displacement or dynamic loads (such as vibration) of the pipeline. Spring brackets are usually used in high temperature, heavy pipelines, equipment connections or hanging pipelines. Spring brackets can compensate for the vertical displacement of the pipeline and reduce stress concentration. In the direction of thermal expansion, choose sliding brackets or spring brackets to avoid stress concentration caused by fixed brackets.

[0054] Limit brackets are used to limit the displacement of pipes in a specific direction, such as to avoid excessive displacement due to thermal expansion. Limit brackets are usually installed at the end or middle of the thermal expansion direction to prevent excessive expansion of pipes due to thermal stress.

[0055] Hangers provide flexible support, allowing the pipe to move freely with thermal expansion or contraction. Hangers are mainly used to suspend pipes to bear vertical loads. For example, hangers are used for long-distance pipes that need to be suspended on roofs or high-altitude pipes, especially in pipe systems with large temperature differences. Hangers usually only bear the weight of the pipe and the vertical load of the medium, but through flexible design, they can provide sufficient support for the pipe while allowing the pipe to have free thermal expansion.

[0056] Seismic brackets are used to resist the impact of external environmental loads such as earthquakes or wind loads on pipelines, ensuring that the pipelines will not fall off or be severely deformed under earthquakes or strong winds. Seismic brackets are suitable for pipeline systems installed in earthquake-prone areas, especially those located in buildings or areas susceptible to environmental impacts. Seismic brackets can provide additional impact resistance in specific directions and ensure the safety of pipelines through structural reinforcement design.

[0057] The rolling bracket allows the pipe to roll freely along its axis to compensate for the axial thermal expansion of the pipe. The rolling bracket is suitable for long straight pipe sections, especially in areas with large temperature differences, or pipe sections that require large displacement compensation. The rolling bracket reduces friction resistance by setting rollers, allowing the pipe to easily move along the axial direction.

[0058] Lateral supports limit the lateral displacement of the pipeline, especially at elbows to prevent lateral bending or displacement of the pipeline. Lateral supports are usually used in unstable locations such as elbows or tees to ensure the stability of the pipeline. Lateral supports allow partial free movement while ensuring that the displacement of the pipeline does not exceed the preset range, and are often used in combination with other types of supports and hangers.

[0059] Vibration-damping brackets are used to reduce vibrations in piping systems caused by fluid flow, equipment operation, etc. Vibration-damping brackets can be used near vibration sources such as pumps and compressors to reduce the impact of vibration on the pipeline. Vibration-damping brackets can absorb or reduce pipeline vibrations through damping design to protect the stable operation of the system.

[0060] In an optional implementation of an embodiment of the present invention, the type of supports and hangers at corresponding positions is determined based on the stress at various positions of the pipeline, including: obtaining application characteristics of each type of supports and hangers in a preset support and hanger library; and matching the stress at various positions of the pipeline with the application characteristics to determine the type of supports and hangers at corresponding positions.

[0061] Based on the application characteristics of the above-mentioned types of supports and hangers, as well as the stress at various locations of the pipeline, the types of supports and hangers at different locations of the pipeline can be determined.

[0062] Step 140: Calculate the span between the supports and hangers based on the target design parameters and the stress at each position.

[0063] The span of the pipeline support and hanger refers to the horizontal distance between two adjacent supports. Determining the appropriate span is very important for the stability, safety and stress control of the pipeline. The main functions of the span include: supporting the weight of the pipeline, controlling the deflection of the pipeline, reducing thermal expansion stress, reducing vibration and dynamic loads, preventing structural damage, meeting regulatory requirements, and preventing local failure of the support and hanger.

[0064] In terms of supporting the weight of the pipeline, the span determines the extent to which the pipeline is supported by the supports and hangers. Through reasonable span design, the supports and hangers can effectively support the weight of the pipeline and the medium inside it, preventing the pipeline from sagging or bending due to its own weight or the gravity of the medium.

[0065] In terms of controlling pipeline deflection, deflection is the amount of deformation of the pipeline under the action of gravity. If the span between the supports is too large, the pipeline may have excessive deflection, causing the pipeline to sink or bend, which in turn affects the flow of the medium in the pipeline, increases the stress of the pipeline, and may even cause leakage or other structural damage.

[0066] In terms of reducing thermal expansion stress, the pipeline will expand or contract when the temperature changes. Reasonable span design can limit the thermal expansion stress of the pipeline and avoid excessive elongation or compression of the pipeline due to temperature difference. Through appropriate support and hanger spacing, the bracket can effectively distribute the stress caused by thermal expansion and prevent pipeline damage.

[0067] In terms of reducing vibration and dynamic loads, long-span pipelines are prone to dynamic loads due to vibration, especially when conveying high-pressure fluids or gases. Reasonable spans help reduce pipeline vibration, increase the stability and reliability of the pipeline system, and extend the service life of the pipeline.

[0068] In terms of preventing structural damage, if the span between supports and hangers is not designed properly, the pipeline may be damaged due to excessive deflection or stress. Excessive spacing between supports and hangers may cause excessive stress on weak links such as pipeline welding points and connecting flanges, thereby causing damage to the pipeline structure.

[0069] In terms of meeting regulatory requirements, the span design of supports and hangers can be carried out according to industry or national standards related to pipeline design (such as ASME, GB, SH specifications, etc.). These standards put forward specific requirements for the span of pipeline supports and hangers under different materials and different working conditions. Designing a reasonable span of supports and hangers is one of the important steps to ensure project compliance.

[0070] In terms of preventing local failure of supports and hangers, if the span between supports and hangers is too large, the supports and hangers may bear too much load, resulting in local failure, such as deformation or falling off of the support. By reasonably designing the span, local overload can be avoided, ensuring that the entire support and hanger system bears the load evenly and prolonging its service life.

[0071] The span design of pipe supports and hangers is to ensure the safe, stable and long-life operation of the pipeline system. The span of the supports and hangers not only determines how the pipeline bears its own weight and the weight of the medium inside, but also controls the impact of thermal expansion stress, vibration and other external forces on the pipeline system. By calculating and designing a reasonable span, the pipeline can maintain good performance and reduce the failure rate in long-term use.

[0072] The calculation of span requires comprehensive consideration of the following factors: pipeline material, pipeline diameter, pipeline wall thickness, medium in the pipeline, pipeline operating temperature, external load, pipeline weight, allowable pipeline deflection, and standard specifications, etc.

[0073] The greater the stiffness of the pipeline material (the higher the E value), the allowable span can be appropriately increased. The yield strength of the material affects the maximum stress that the pipeline can withstand, which in turn affects the maximum span of the pipeline. The weight of the pipeline itself (including the weight of the pipeline material, insulation layer and conveying medium, etc.) directly affects the amount of pipeline sag, so it is necessary to calculate a reasonable span through load. The larger the pipeline diameter, the greater the pipeline weight. Therefore, for pipelines with large diameters, the span is generally shortened to avoid excessive bending or sagging of the pipeline. Pipes with thicker pipe walls are more rigid and can allow for larger spans. The medium conveyed in the pipeline will increase the total weight of the pipeline. Therefore, the heavier the medium, the smaller the span should be. Denser media (such as liquids) will generate greater forces relative to light gases. Pipeline material properties change with pipeline temperature. For example, the stiffness of some materials decreases with increasing temperature, which will limit the maximum allowable span. At high temperatures, the pipeline will generate additional stress due to thermal expansion, which affects the stiffness of the pipeline and requires a reduced span. External loads include wind loads, snow loads, earthquake forces, etc., especially in open-air or high-altitude pipelines, the impact of these factors on the span of supports and hangers needs to be considered. Deflection is the maximum allowable deformation of the pipeline under load. Usually, the deflection allowed in pipeline design is 1 / 400 to 1 / 500 of the pipeline length, and the specific value can be adjusted according to the design specifications and project requirements. Different regions have different specifications for pipeline design. Common specifications include: ASME B31.3 (Process Piping), which is usually used for industrial process piping; ASME B31.1 (Power Piping), which is used for power piping systems; and GB50316 (Industrial Metal Pipeline Design Specifications), SH-T3073 (Petrochemical Pipeline Support and Hanger Design Specifications), etc. These specifications usually provide empirical formulas or recommended values ​​for calculating spans.

[0074] For example, for carbon steel pipelines, when the working temperature is at room temperature and when transporting liquids, the common support and hanger spans are: pipe diameter is less than 25mm: support and hanger span is about 1.5 meters; pipe diameter is between 25-100mm: support and hanger span is 2-3 meters; pipe diameter is between 100-250mm: support and hanger span is 3-4.5 meters; pipe diameter is greater than 250mm: support and hanger span is 4.5-6 meters.

[0075] In an optional implementation of an embodiment of the present invention, the span between each support and hanger is calculated according to the target design parameters and the stress at each position, including: obtaining a preset mapping relationship for calculating the span of the support and hanger; wherein the preset mapping relationship includes: a preset span calculation formula and / or a preset span determination table; and calculating the span between each support and hanger according to the target design parameters, the stress at each position, and the preset mapping relationship.

[0076] For example, the spacing between supports and hangers can be determined by formulas or empirical tables. For example, for the pipe span under simple conditions, the stiffness condition and strength condition of a three-span continuous beam bearing uniformly distributed load can be used to calculate, and the smaller value of the stiffness condition and strength condition calculation results is used as the support and hanger span. Among them, the stiffness condition is The strength condition is Where, L is the span of the pipe support bracket (m), E t is the elastic modulus of the pipeline material at the design temperature (Mpa), I is the section inertia moment of the pipeline after deducting the corrosion allowance and negative deviation (mm 4 ), W is the bending section modulus of the pipeline after deducting the corrosion allowance and negative thickness deviation (mm 3 ), q is the uniformly distributed load per meter of pipeline (including pipeline deadweight, medium weight, etc.), unit is N / m; [σ] t It is the allowable stress (Mpa) of the pipeline material at the design temperature. The preset span determination table can be determined based on factors related to the span of the support and hanger, and the correlation between the factors and the span.

[0077] When arranging supports and hangers, try to keep them uniform to avoid stress concentration. Especially in long straight pipe sections, arrange sliding supports to balance the load. Fixed supports can be set for key locations. For example, fixed supports should be set at elbows, branch points, and equipment connections to control the displacement direction of the pipeline and ensure the stability of the system. When arranging supports and hangers, too many fixed supports should also be avoided. Too many fixed supports will limit the thermal expansion of the pipeline and cause excessive thermal stress. Therefore, the number of fixed supports should be reasonably controlled.

[0078] Step 150: construct a pipeline support and hanger arrangement structure based on the support and hanger type and span, and generate a pipeline support and hanger selection result.

[0079] According to the load calculation results, pipeline size and displacement, you can select the appropriate support and hanger model and specification in the selection table. The maximum load capacity range of each support and hanger. The pipe size applicable to different supports and hangers. The maximum displacement allowed by the supports and hangers. According to the material, diameter, weight and other parameters of the pipeline, calculate the reasonable installation spacing of the supports and hangers to ensure the stability of the pipeline. Determine the telescopic freedom of the supports and hangers based on the thermal expansion and contraction of the pipeline when heated or the displacement caused by other factors. Determine the installation position of the supports and hangers based on the available support structures (such as beams, walls or ground) around the pipeline system. Supports and hangers should be arranged at key locations such as turning points, connection points, heavy load areas, thermal expansion control points, etc. of the pipeline to ensure the stability of the pipeline system.

[0080] After the initial selection is completed, the selection results of the supports and hangers can be checked to ensure that the load capacity, displacement compensation capacity, etc. of the supports and hangers meet the design requirements. Especially in large-diameter, high-temperature (low-temperature), and high-pressure pipelines, the selection of supports and hangers is crucial to pipeline safety and requires design verification. For complex pipeline systems, especially long-distance pipelines or high-temperature (low-temperature) and high-pressure pipelines, professional pipeline stress analysis software can be used to accurately design the support and hanger system. Through these software, the thermal expansion, displacement, and stress conditions of the pipeline can be simulated, thereby optimizing the layout and selection of supports and hangers.

[0081] Therefore, pipe supports and hangers with different support forms are selected at different positions of the pipeline, and the span between the pipe supports and hangers is calculated in combination with the acquired pipeline information to meet the intelligent construction of pipe supports and hangers for complex pipelines.

[0082] In addition, the design parameters of the pipeline, stress analysis results, cost-effectiveness, and construction convenience can be comprehensively considered. Through intelligent algorithms, multi-parameter optimization and selection of pipeline supports and hangers can be performed to obtain the optimal pipeline support and hanger configuration plan, build the pipeline support and hanger layout structure, and generate pipeline support and hanger selection results. When selecting appropriate support and hanger materials and design solutions, it is necessary to ensure that the cost is lowest while meeting technical requirements. When determining the support and hanger parameters, the construction difficulty should also be considered to ensure that the design solution can be smoothly installed and maintained on site.

[0083] In an optional implementation of an embodiment of the present invention, a support and hanger arrangement structure for a pipeline is constructed according to the support and hanger types and spans, including: determining the parts components of the supports and hangers according to the material, working pressure, temperature, medium properties and environmental information in the target design parameters; constructing a support and hanger arrangement structure for the pipeline according to the support and hanger types and spans; structurally coordinating the parts components according to the support and hanger arrangement structure, and adding the coordinated parts components to the support and hanger arrangement structure.

[0084] External environmental conditions will also affect the design of supports and hangers, especially the material selection and structural design. For example, extreme temperature environments (such as high temperature and high-cold areas) may affect the selection of support and hanger materials. Therefore, according to the temperature of the pipeline, the high temperature or low temperature resistance of the supports and hangers is considered, and parts and components are added. For another example, if the pipeline and the supports and hangers are in an environment where corrosive gases, moisture or chemicals are in contact, the supports and hangers need to use corrosion-resistant parts and components, or the supports and hangers need to be treated with anti-corrosion. For another example, in earthquake-prone areas, pipeline supports and hangers must meet seismic requirements to ensure their stability during vibration. For another example, for outdoor installed piping systems, especially high-altitude pipelines, wind force may affect the design of supports and hangers. Consider the thermal expansion and contraction of the pipeline caused by temperature differences, and determine the type of supports and hangers that need to absorb thermal stress (such as sliding supports or spring supports).

[0085] For example, for sliding brackets or spring brackets, it is necessary to select a suitable model according to the displacement of the thermal expansion of the pipeline. The material of the support and hanger (such as carbon steel, stainless steel, etc.) and its surface parts and components (such as hot-dip galvanizing, spray painting, etc.) need to adapt to the environmental conditions to prevent corrosion. According to the working environment of the pipeline, select appropriate anti-corrosion or heat-insulating measures for the support and hanger parts and components. If the pipeline medium is a high-temperature medium, the support and hanger needs to be equipped with heat-insulating parts and components to prevent the support and hanger from being directly subjected to high temperatures, causing material aging or failure. For pipelines outdoors or in corrosive environments, the support and hanger also needs to be equipped with parts and components for anti-corrosion treatment, such as anti-rust paint, hot-dip galvanizing, etc.

[0086] On the basis of the above implementation mode, optionally, before obtaining the application characteristics of each support and hanger type in the preset support and hanger library, it also includes: collecting support and hanger information, and classifying each support and hanger according to the application characteristics in the support and hanger information to generate a preset support and hanger library; in response to the information adding instruction, adding the corresponding part components, support and hanger parameters and support and hanger performance description in the preset support and hanger library.

[0087] For example, through market research, manufacturer information, engineering practice and other channels, we can obtain information on various types of pipe supports and hangers. We can classify pipe supports and hangers according to their design characteristics and applicable scenarios. Each type of support and hanger has detailed technical parameters and performance descriptions in the library, providing sufficient reference for the subsequent selection process.

[0088] On this basis, users can add various parts components for each pipe support and hanger. These parts components can be pre-set standard parts, or other pipe supports and hangers can be used as components to form a more complex structure. When adding parts components, you can select specific pipes and pipe support and hanger components, and set constraints to ensure that the components can only be used on qualified pipes. This flexible component addition function can build the most suitable pipe support and hanger structure according to specific engineering needs.

[0089] Each component can have specific functions and roles, such as enhancing the support capacity of the pipeline, providing additional equipment installation points, or improving the stability of the pipeline in a specific environment. These functions can be intuitively configured and managed through the system's graphical user interface, ensuring that users can flexibly adjust and optimize the pipe support and hanger structure during the design process. The establishment of the pipe support and hanger library is not limited to the current types of pipe supports and hangers, but also includes possible new types of pipe supports and hangers and technological advances in the future. The pipe support and hanger library can be continuously updated and improved based on user feedback and needs in actual applications to ensure that it can always provide the latest and most suitable pipe support and hanger selection solutions.

[0090] In an embodiment of the present invention, after the selection result of the pipe support and hanger is generated, a three-dimensional rendering display can be performed to present the position, quantity and type of the pipe support and hanger on the pipe in a clear and intuitive manner. The form of drawing directly on the pipe is not only intuitive and easy to understand, but also convenient for designers to quickly understand the selection logic and results of the algorithm. When displaying, necessary text descriptions and explanations can also be provided, such as the reasons for the selection of the pipe support and hanger type, the analysis of the rationality of the layout, and the consideration of performance optimization.

[0091] After the display, it can also support fine-tuning of the position of pipe supports and hangers, optimization of the support structure, and suggestions for material selection, etc. For example, it can obtain the user's fine-tuning instructions to adjust the support and hanger layout to further improve the performance and stability of the pipe supports and hangers, while ensuring the overall coordination and aesthetics with the pipeline system.

[0092] The technical solution of the embodiment of the present invention can automatically identify the parameter information of the constructed pipeline, and determine the design parameters of the pipeline support and hanger through intelligent analysis of these data, and improve the accuracy, efficiency and overall design quality of the selection with the help of the intelligent support provided by the computer-aided system. Through the stress analysis of the pipeline, the span of the pipeline support and hanger construction is calculated, and the optimal configuration scheme of the pipeline support and hanger is determined, which reduces the influence of human subjective factors on the construction of the pipeline support and hanger, and greatly reduces the probability of errors in the process of constructing the pipeline support and hanger.

[0093] An exemplary use case of the method provided by the embodiment of the present invention is: for a carbon steel pipeline transporting steam, the parameters are: the outer diameter of the pipeline is 500mm, the wall thickness of the pipeline is 10mm, the material of the pipeline is carbon steel, the medium is high-temperature steam, the working pressure is 5MPa, and the working temperature is 350°C. According to the above pipeline parameters, the dead weight of the pipeline and the weight of the steam are calculated to determine the static load of the pipeline. According to the temperature difference of 350°C, the thermal expansion of the pipeline is calculated, and then the displacement of the support and hanger is determined. Due to the flow of high-temperature steam in the pipeline, it is determined to select a sliding bracket that can compensate for thermal expansion. Fixed brackets are set at some key positions to control the displacement. At the same time, it is determined to select a suitable spring bracket to balance the thermal stress. Since the pipeline works in a high-temperature environment, the support and hanger should be made of high-temperature resistant materials, and consider adding thermal insulation gaskets at the contact point between the bracket and the pipeline. Determine the most suitable type and quantity of support and hanger according to the above steps to ensure that the design meets the pipeline operation requirements.

[0094] The technical solution of the embodiment of the present invention obtains the design parameters of the pipeline and performs data analysis based on the design parameters to determine the target design parameters that affect the layout of supports and hangers; performs pipeline stress analysis based on the target design parameters to determine the stresses at different positions of the pipeline; determines the type of supports and hangers at corresponding positions based on the stresses at various positions of the pipeline; calculates the span between various supports and hangers based on the target design parameters and the stresses at various positions; constructs a support and hanger layout structure for the pipeline based on the support and hanger types and spans, and generates a pipeline support and hanger selection result, thereby solving the problem of automatic selection of pipeline supports and hangers, reducing manpower consumption, and improving support and hanger design efficiency and accuracy.
