Description

Technical Field

[0001] The present disclosure relates to the technical field of support and hanger arrangement, and in particular to a pipe support assembly. Background Art

[0002] The installation of supports and hangers for thermal pipes is crucial to ensuring the safe and stable operation of the piping system. On the one hand, temperature changes during operation cause thermal pipes to expand and contract. Supports and hangers provide reasonable constraints and guidance, allowing the pipes to expand and contract within a certain range, preventing deformation and rupture caused by excessive accumulation of thermal stress, and ensuring the integrity of the pipe structure. Furthermore, the medium within the pipes is high temperature and high pressure, and the supports and hangers withstand various loads, firmly supporting the pipes and avoiding accidents such as leaks caused by pressure overload, thereby ensuring the safety of personnel and equipment. On the other hand, supports and hangers can reduce pipe vibration caused by factors such as medium flow, reduce the risk of pipe damage and noise, improve operational stability and reliability, and ensure the normal supply of heat. At the same time, they bear weight and limit displacement, preventing excessive deformation and stress concentration, protecting the pipes, extending their lifespan, and ensuring the efficiency and safety of the heating system.

[0003] Currently, computer programs are commonly used to perform stress analysis on thermal pipe supports and hangers to determine the optimal installation location. Traditional computer stress calculations for thermal pipes have many drawbacks. Stress calculations are highly complex. Constructing a calculation model requires considering the precise geometry of the pipe, various connecting components, and support forms. This requires a large number of input parameters, and the process of describing the pipe direction and setting component characteristics is cumbersome and prone to errors. At the same time, a wide range of calculation parameters must be considered, including material properties, temperature changes, and various loads. These parameters are closely related, making it difficult to determine their exact values. A small deviation can cause the results to be inaccurate. Utility Model Content

[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0029] This solution provides a pipe support assembly, which includes a pipe 1, an accessory 2 arranged on the pipe 1, and a bracket arranged on both sides of the accessory 2 for supporting the pipe 1, the weight MA of the accessory 2 is greater than twice the weight MB of the pipe 1 with a length of the maximum allowable span, and the distance between the bracket and the accessory 2 is less than the nominal diameter DN of the pipe 1.

[0030] The span refers to the length of the pipe between two brackets (or other supports), the maximum allowable span is the maximum length of the pipe 1 between the two brackets, and the maximum permissible span is the maximum length of the pipe 1 when the accessory 2 is installed on the pipe 1.

[0031] When other accessories 2 are installed on the pipeline 1, the weight of the accessories 2 is greater at the same length, which results in an increase in the overall weight of the pipeline 1. Therefore, the span of the pipeline 1 needs to be adjusted accordingly.

[0032] When the weight of accessory 2 exceeds twice the weight MB of the maximum allowable span of pipeline 1, the weight of accessory 2 is relatively large, so brackets are set on both sides of it to support it. The distance between the two brackets and accessory 2 is less than the nominal diameter DN of pipeline 1 to avoid the distance between the brackets and accessory 2 being too large to provide sufficient support.

[0033] There are two methods for determining the maximum allowable span: calculation and table lookup. The more commonly used method is the table lookup, as shown in the table below.

[0034] Recommended maximum allowable span of pipeline

[0035]

[0036]

[0037] In this solution, for accessories with heavier weight, two brackets can be used to support the accessories, ensuring that the distance is less than the nominal diameter to avoid insufficient support. There is no need to consider calculation parameters such as material properties, temperature changes, and multiple loads, which simplifies the calculation of pipeline span and improves the installation efficiency of the pipeline while ensuring the load-bearing capacity and reliability of the pipeline under static and dynamic loads.

[0038] In some embodiments, the two brackets are respectively a first fixed bracket 4 and a first guide bracket 3. Figure 3 As shown, the two brackets are respectively a fixed bracket and a guide bracket, wherein the pipe 1 is relatively fixed to the first fixed bracket 4, and the pipe 1 cannot move axially relative to the first fixed bracket 4. The pipe 1 is supported on the first guide bracket 3 and can move axially relative to the first guide bracket 3. The pipe 1 and the accessory 2 have a certain degree of expansion and contraction deformation. One of the brackets is relatively fixed to the pipe 1, which can limit the accessory 2 within a certain range and provide stable support for the accessory 2 and the pipe 1. The other bracket can allow the expansion and contraction deformation of the accessory 2 and the pipe 1, as shown in FIG. Figure 1 and Figure 3 The guide bracket may include a sleeve for accommodating the pipe 1 to pass through.

[0039] In some embodiments, the next span unit adjacent to the first guide bracket 3 is a straight pipe, and the next span unit is supported by the second guide bracket 6. The next span unit refers to another section of the pipe located between the two brackets and adjacent to a section of the pipe between the two brackets. For example, the next span unit adjacent to the first guide bracket 3 is the pipe 1 between the first guide bracket 3 and the second guide bracket 6. Since this section of the pipe 1 is a straight pipe, it can be supported by a bracket in the form of a guide bracket, which only needs to limit the lateral movement of the pipe 1, while allowing the pipe 1 to deform in a telescopic manner, such as Figure 1 shown.

[0040] In addition, in some embodiments, the next span unit adjacent to the first guide bracket 3 is a curved pipe, which is supported by the second fixed bracket 7. The next span unit, which is a curved pipe, is supported by the first guide bracket 3 and the second fixed bracket 7. Since the extension direction of the pipeline 1 changes, that is, it forms a curved pipe, it needs to be supported by a fixed bracket to limit its relative movement in all directions and ensure the stability of the pipeline 1.

[0041] In some embodiments, the next span unit includes a first straight pipe section 8 adjacent to the second fixed support 7 and a second straight pipe section 9 adjacent to the first guide support 3, and the length ratio of the first straight pipe section 8 to the second straight pipe section 9 is: l1 / l2≤1.5. Figure 2 As shown, the distance between the turning point of the curved pipe and the attachment 2 (and the second guide bracket 6) is basically determined. Due to the existence of the turn, the position of the second fixed bracket 7 needs to be designed accordingly, that is, the ratio of the distance between the second fixed bracket 7 and the turning point (the length of the first straight pipe 8) and the distance between the first guide bracket 3 and the turning point (the length of the second straight pipe 9) is less than or equal to 1.5, l1 / l2≤1.5, that is, the distance between the second fixed bracket 7 and the turning point should not be too large, and the second fixed bracket 7 provides support for the curved pipe to reduce the load at the first guide bracket 3.

[0042] In some embodiments, the angle of the bend is a right angle. Figure 2 As shown, the shape of the bent pipe is a right angle, and the first section of the straight pipe 8 is perpendicular to the second section of the straight pipe 9, wherein the second section of the straight pipe 9 can extend horizontally and the second section of the straight pipe 8 extends vertically. Therefore, as described above, the second fixed bracket 7 provides support for the second section of the straight pipe 9, reducing the load at the first guide bracket 3.

[0043] In some embodiments, the accessory 2 is a valve including a control rod 5, wherein the eccentric mass of the valve satisfies the following condition: h·MA>5.7I / D0, and the control rod 5 is supported by a support frame, where h is the distance from the pipe axis to the valve's center of gravity, MA is the valve weight, D0 is the outer diameter of the pipeline 1, and I is the moment of inertia of the pipeline 1. In other words, when the eccentric moment of the valve is large, an additional support frame can be added to support the control rod 5 of the valve to prevent the eccentric force of the valve from causing the pipeline 1 to deviate.

[0044] In some embodiments, the joystick 5 extends horizontally, and the support frame extends horizontally or vertically. The pipeline 1 can extend horizontally, the joystick 5 extends horizontally, and the support frame can extend horizontally or vertically. The support frame can be set on the ground or on a wall.

[0045] In addition, in some other embodiments, the joystick 5 extends vertically and the support frame extends horizontally. The joystick 5 is arranged in a vertical direction, and the support frame extends horizontally and supports the joystick 5, which can be arranged on a wall.

[0046] In some embodiments, the accessory 2 is a valve, a flange, or a measuring instrument.
