Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a BFPE multi-ribbed reinforced pipe. Background Technology

[0002] A pipeline is a tubular system used to transport media such as gases, liquids, or solid particles. It is usually composed of pipes, fittings, valves, and auxiliary equipment. Its core function is to achieve safe and efficient transmission of media. It is widely used in energy, municipal, industrial, and construction fields. Pipeline materials include metals, plastics, and composite materials. The design must take into account pressure, temperature, corrosiveness, and environmental conditions. Modern pipeline systems also integrate intelligent monitoring technology to achieve automated management such as leak detection and flow control. It is one of the basic infrastructures that ensure the operation of society.

[0003] However, traditional pipes are mostly made of a single material, and their structure lacks composite reinforcement design, which easily leads to poor overall strength.

[0004] For example, in high-load scenarios such as municipal drainage or chemical transportation, ordinary plastic pipes are prone to excessive deformation or even rupture under soil pressure or vehicle load due to insufficient ring stiffness. Pipes made of a single material have weak impact resistance and are prone to brittleness under low temperature environment or external impact. They have high maintenance costs and short service life, making it difficult to meet the long-term stable operation requirements of complex working conditions. Utility Model Content

[0005] This utility model discloses a BFPE multi-ribbed reinforced tube, which aims to solve the technical problem that the tube made of a single material lacks a composite reinforcement design and is prone to poor overall strength.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A BFPE multi-ribbed reinforced pipe includes an outer matrix layer and an inner matrix layer, a buffer mechanism is provided between the outer matrix layer and the inner matrix layer, and a support mechanism is provided on the outer circumferential wall of the outer matrix layer. The buffer mechanism includes a buffer cavity, and an inner rib is provided on the inner wall of the buffer cavity. The inner rib is provided with a plurality of connecting ribs that are evenly distributed.

[0007] By adopting the above technical solution, the impact resistance of the pipeline is significantly improved. When the pipeline is subjected to external impact, the buffer cavity can effectively absorb and disperse the impact energy, preventing the pipeline from breaking due to excessive local stress, thereby extending the service life of the pipeline and reducing maintenance costs. In the manufacturing process, an outer matrix layer and an inner matrix layer are first made, and then a space for a buffer cavity is reserved between the two. Spiral internal ribs are set on the inner wall of the buffer cavity, and several connecting ribs are evenly distributed on the internal ribs. The connecting ribs and the internal ribs form an effective buffer structure layer, which evenly disperses the impact force on the outer wall of the pipeline.

[0008] As a further embodiment of this utility model: the inner rib has a spiral structure, the inner rib is made of glass fiber reinforced polyester, and the connecting rib is made of carbon fiber reinforced polymer.

[0009] By adopting the above technical solutions, the inner ribs are made of glass fiber reinforced polyester, which enhances the overall strength and rigidity of the pipeline. This material has high strength and corrosion resistance, which enables the pipeline to maintain stable performance under complex working conditions, improving the reliability and safety of the pipeline. The connecting ribs are made of carbon fiber reinforced polymer, which further enhances the connection strength and durability of the pipeline. The high strength of carbon fiber makes the connecting ribs less prone to breakage when subjected to tensile force, ensuring the integrity and stability of the pipeline structure.

[0010] As a further embodiment of this utility model: the support mechanism includes two outer ribs, which are disposed on the outer circumferential outer wall of the outer substrate layer.

[0011] By adopting the above technical solution, the support mechanism includes two symmetrically arranged outer ribs, which significantly enhances the ring stiffness of the pipeline. The arrangement of the outer ribs enables the pipeline to better resist deformation and maintain the stability of the pipeline shape when subjected to soil pressure or vehicle load.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a buffer mechanism, when the pipeline is impacted by external forces, the spiral inner ribs on the inner wall of the buffer cavity and the carbon fiber connecting ribs form a multi-layer energy absorption structure, which effectively disperses the impact stress, avoids local stress concentration, and the closed-cell polyethylene foam filling layer further attenuates the vibration, so that the pipeline can still maintain structural integrity under complex working conditions, significantly reduce the risk of rupture, and extend its service life.

[0013] 2. Two spiral outer ribs symmetrically arranged on the outer circumference of the outer substrate layer form a three-dimensional reinforced frame through rigid support of high-density polyethylene material. This structure can effectively resist lateral soil pressure and dynamic vehicle loads, improve the ring stiffness of the pipeline, and ensure that the circular cross-section is maintained for a long time in buried or overhead scenarios, avoiding the decrease in media transportation efficiency due to deformation.

[0014] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A BFPE multi-ribbed reinforced pipe includes an outer matrix layer 1 and an inner matrix layer 3. A buffer mechanism is provided between the outer matrix layer 1 and the inner matrix layer 3. A support mechanism is provided on the outer circumferential outer wall of the outer matrix layer 1. The buffer mechanism includes a buffer cavity 4. An inner rib 5 is provided on the inner wall of the buffer cavity 4. Several connecting ribs 6 are provided on the inner rib 5 at equal intervals.

[0022] The outer matrix layer 1 is made of modified polypropylene, and the inner matrix layer 3 is made of polytetrafluoroethylene.

[0023] The outer matrix layer 1 is made of modified polypropylene, which has excellent chemical corrosion resistance and heat resistance, enabling the pipeline to operate stably for a long time under harsh environmental conditions and reducing the frequency of pipeline damage and replacement caused by environmental factors. The inner matrix layer 3 is made of polytetrafluoroethylene, which has an extremely low coefficient of friction and excellent chemical corrosion resistance, enabling the pipeline to reduce energy loss when transporting media, while resisting the erosion of various chemical substances and ensuring the long-term performance of the pipeline.

[0024] In the specific implementation process, by setting up a buffer mechanism, the impact resistance of the pipeline is significantly improved. When the pipeline is subjected to external impact, the buffer cavity 4 can effectively absorb and disperse the impact energy, preventing the pipeline from breaking due to excessive local stress, thereby extending the service life of the pipeline and reducing maintenance costs. In the manufacturing process, the outer matrix layer 1 and the inner matrix layer 3 are first made, and then the space of the buffer cavity 4 is reserved between the two. The inner wall of the buffer cavity 4 is provided with a spiral structure inner rib 5, and several connecting ribs 6 are evenly distributed on the inner rib 5. The connecting ribs 6 and the inner rib 5 form an effective buffer structure layer, which evenly disperses the impact force on the outer wall of the pipeline.

[0025] Reference Figure 4 In a preferred embodiment, the inner rib 5 has a spiral structure and is made of glass fiber reinforced polyester, while the connecting rib 6 is made of carbon fiber reinforced polymer.

[0026] Specifically, the inner rib 5 is made of glass fiber reinforced polyester, which enhances the overall strength and rigidity of the pipeline. This material has high strength and corrosion resistance, which enables the pipeline to maintain stable performance under complex working conditions, improving the reliability and safety of the pipeline. The connecting rib 6 is made of carbon fiber reinforced polymer, which further enhances the connection strength and durability of the pipeline. The high strength of carbon fiber makes the connecting rib 6 less prone to breakage when subjected to tensile force, ensuring the integrity and stability of the pipeline structure.

[0027] Reference Figure 2 In a preferred embodiment, the buffer cavity 4 is filled with closed-cell polyethylene foam. The closed-cell polyethylene foam filling the buffer cavity 4 can effectively absorb and disperse the impact energy of external forces on the pipeline, avoid pipeline rupture caused by local stress concentration, and prevent water penetration, avoid material corrosion and performance degradation caused by humid environment, extend pipeline service life and reduce maintenance costs.

[0028] Reference Figure 1 and Figure 3 In a preferred embodiment, the support mechanism includes two outer ribs 2, which are disposed on the outer circumferential outer wall of the outer substrate layer 1. Both outer ribs 2 are spiral structures and are symmetrically arranged. The outer ribs 2 are made of high-density polyethylene.

[0029] It should be noted that the outer reinforcing bar 2 adopts a spiral structure and is symmetrically arranged, and high-density polyethylene is selected as the outer reinforcing bar 2. This design enables the pipeline to distribute stress more evenly when subjected to uneven external forces, avoids the risk of rupture caused by local stress concentration, and improves the overall resistance to damage of the pipeline.

[0030] In particular, the support mechanism includes two symmetrically arranged outer stiffeners 2, which significantly enhance the ring stiffness of the pipeline. The arrangement of the outer stiffeners 2 enables the pipeline to better resist deformation and maintain the stability of the pipeline shape when subjected to soil pressure or vehicle load.

[0031] Working principle: When in use, the two symmetrically arranged spiral outer ribs 2 can resist soil or vehicle loads and prevent pipeline deformation. When the pipeline is subjected to strong external impact, the outer base layer 1 first bears the impact force, the closed-cell polyethylene foam in the buffer cavity 4 absorbs part of the energy, and the spiral inner ribs 5 and carbon fiber connecting ribs 6 disperse the remaining stress to ensure stable pipeline operation.

[0032] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
