Description

Technical Field

[0001] This utility model relates to the field of pressure-resistant pipe technology, and in particular to a steel wire mesh reinforced pipe. Background Technology

[0002] Steel wire mesh reinforced plastic composite pipe uses high-strength overmolded steel wire mesh skeleton and thermoplastic polyethylene as raw materials. The steel wire mesh serves as the skeleton reinforcement of the polyethylene plastic pipe, with high-density polyethylene as the matrix. High-performance HDPE modified bonding resin is used to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene, giving it an excellent composite effect. Because the high-strength steel wire reinforcement is covered in continuous thermoplastic plastic, this composite pipe overcomes the shortcomings of both steel pipes and plastic pipes while retaining their respective advantages.

[0003] Existing steel wire mesh reinforced pipes have poor external pressure adaptability. In order to improve their external pressure adaptability, a layer of steel strip is generally laminated to the outside of the steel wire mesh skeleton. However, the peel resistance is poor and the production cost of the pipe is increased.

[0004] The existing patent (publication number: CN213871498U) discloses a steel wire mesh skeleton pipe. In this utility model, the steel wire skeleton has an inner steel wire ring that supports the steel wire mesh, while the outer steel wire ring tightens the steel wire mesh, thus forming an external force-bearing body supported by the inner steel wire ring, which greatly improves the external pressure resistance of the pipe body.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the composite stability of the steel wire mesh and plastic layer in existing steel wire mesh reinforced pipes is poor, and delamination is likely to occur under long-term use, temperature changes, or pressure fluctuations, which seriously threatens the reliability of the pipeline during use. Furthermore, when faced with extreme high and low temperatures, strong acid and alkali corrosion, and frequent pressure shocks, its overall performance is difficult to maintain stability, which greatly limits its application range.

[0006] Therefore, a steel wire mesh reinforced pipe is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a steel wire mesh reinforced pipe that can solve the problems of poor composite stability of the steel wire mesh and plastic layer in existing steel wire mesh reinforced pipes, which are prone to delamination under long-term use, temperature changes or pressure fluctuations, thus seriously threatening the reliability of the pipeline during use. Furthermore, when facing extreme high temperature, low temperature, strong acid and alkali corrosion and frequent pressure impact conditions, its overall performance is difficult to maintain stability, which greatly limits its application scope.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a steel wire mesh skeleton pipe, including an inner lining pipe, a support mesh assembly is provided on the outside of the inner lining pipe, and a weather-resistant protective pipe is bonded to the outside of the support mesh assembly;

[0009] The branch mesh assembly includes an inner transition adhesive layer bonded to the outside of the inner liner tube. A protective mesh structure is provided on the outside of the inner transition adhesive layer. An outer transition adhesive layer is bonded to the outside of the protective mesh structure. An impact-resistant protective layer is bonded to the outside of the outer transition adhesive layer. The outside of the impact-resistant protective layer is bonded to the inside of the weather-resistant protective tube.

[0010] Preferably, the protective mesh structure includes a main steel wire mesh support layer bonded to the outside of the inner transition adhesive layer, and the main steel wire mesh support layer is located on the outside of the inner liner tube.

[0011] Preferably, a secondary wire mesh auxiliary layer is provided on the outside of the main wire mesh support layer. The secondary wire mesh auxiliary layer and the main wire mesh support layer are laid in a 45-degree cross-weaving manner, and the outside of the secondary wire mesh auxiliary layer is bonded to the inside of the outer transition bonding layer.

[0012] Preferably, a micro-damping rubber block is embedded in the inner side of the main wire mesh support layer and the secondary wire mesh auxiliary layer, and the micro-damping rubber block is located at the intersection node of the main wire mesh support layer and the secondary wire mesh auxiliary layer.

[0013] Preferably, the inner liner is made of polyetheretherketone (PEEK) material, and the thickness of the inner liner is 8-12 mm.

[0014] Preferably, the inner transition adhesive layer is made of modified polyurethane resin material, and the outer transition adhesive layer is made of silicone-modified epoxy resin material.

[0015] Preferably, the main wire mesh support layer is made of high-strength alloy steel wire, and the secondary wire mesh auxiliary layer is made of high-strength stainless steel wire.

[0016] Preferably, the impact-resistant protective layer is made of a composite material of polycarbonate and an impact modifier, and the thickness of the impact-resistant protective layer is 4-7 mm.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up a support mesh component, the inner transition bonding layer acts like strong glue, tightly connecting the inner liner tube and the protective mesh structure, greatly improving the composite stability of the protective mesh structure and the inner liner tube, effectively eliminating the risk of delamination under long-term use, temperature fluctuations and pressure changes, and ensuring stable use. At the same time, the outer transition bonding layer seamlessly connects the protective mesh structure and the impact-resistant protective layer, so that each layer can work together to bear the force. When facing complex external impacts, it can quickly disperse energy, comprehensively strengthen the overall mechanical properties, and greatly expand its application range.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A steel wire mesh skeleton pipe includes an inner liner pipe 1, a support mesh assembly 2 is provided on the outside of the inner liner pipe 1, and a weather-resistant protective pipe 3 is bonded to the outside of the support mesh assembly 2.

[0029] The branch mesh assembly 2 includes an inner transition adhesive layer 201 bonded to the outside of the inner liner tube 1. A protective mesh structure 202 is provided on the outside of the inner transition adhesive layer 201. An outer transition adhesive layer 203 is bonded to the outside of the protective mesh structure 202. An impact-resistant protective layer 204 is bonded to the outside of the outer transition adhesive layer 203. The outside of the impact-resistant protective layer 204 is bonded to the inside of the weather-resistant protective tube 3.

[0030] In this embodiment: By setting the branch mesh component 2, when the medium is transported in the inner liner pipe 1, its inner wall is smooth, the friction of the fluid is small, and the medium flows smoothly, which can not only speed up the transportation efficiency but also reduce energy consumption, laying a solid foundation for stable transportation operation. Subsequently, the inner transition bonding layer 201 plays its role, tightly adhering the protective mesh structure 202 to the outside of its inner liner pipe 1. In the face of temperature changes and pressure fluctuations, this connection is stable and reliable, ensuring the stability of the protective mesh structure 202 adhering to the outside of the inner liner pipe 1, preventing delamination, and allowing each layer to work together. The protective mesh structure 202, with its excellent tensile, torsional, and shear resistance, easily copes with external forces from different directions. When the pipeline encounters external impact, the bonded to the outer liner pipe remains intact. The outer impact-resistant protective layer 204 of the outer transition bonding layer 203 responds immediately. It is made of special composite material and has a high elastic modulus. It absorbs and disperses the impact energy instantly, which can effectively buffer the impact and resist damage such as accidental impact, construction collision or ground subsidence. It ensures the continuity and stability of the inner liner pipe 1 during transportation. The weather-resistant protective pipe 3, as the outermost line of defense, is made of ethylene-vinyl acetate copolymer with added ultraviolet absorbers, antioxidants and other additives. The ultraviolet absorber blocks ultraviolet rays from damaging the pipe and the antioxidant inhibits the oxidation reaction and prevents the pipe from aging and deteriorating. In outdoor or harsh weather conditions, the weather-resistant protective pipe 3 protects the internal structure and greatly extends the service life of the pipeline.

[0031] Specifically, such as Figure 3 As shown, the protective net structure 202 includes a main steel wire mesh support layer 2021 bonded to the outside of the inner transition adhesive layer 201, and the main steel wire mesh support layer 2021 is located on the outside of the inner liner tube 1.

[0032] Specifically, such as Figure 3 As shown, a secondary wire mesh auxiliary layer 2022 is provided on the outside of the main wire mesh support layer 2021. The secondary wire mesh auxiliary layer 2022 and the main wire mesh support layer 2021 are laid in a 45-degree cross weaving manner. The outside of the secondary wire mesh auxiliary layer 2022 is bonded to the inside of the outer transition bonding layer 203.

[0033] Specifically, such as Figure 3As shown, a micro damping rubber block 2023 is embedded inside the main wire mesh support layer 2021 and the secondary wire mesh auxiliary layer 2022. The micro damping rubber block 2023 is located at the intersection of the main wire mesh support layer 2021 and the secondary wire mesh auxiliary layer 2022.

[0034] In this embodiment: By setting up a protective net structure 202, the main wire mesh support layer 2021 is bonded to the outside of the inner transition bonding layer 201 and located on the outside of the inner liner tube 1, providing solid radial support for the inner liner tube 1. The secondary wires are set on the outside of the main wire mesh support layer 2021. The two are laid in a 45-degree cross weaving method. This unique weaving method makes the protective net structure 202 have excellent tensile, torsional and shear resistance in all directions, easily coping with external forces in different directions. Moreover, the inner sides of the main wire mesh support layer 2021 and the secondary wire mesh auxiliary layer 2022 are embedded with micro damping rubber blocks 2023 at the intersection nodes. When the inner liner tube 1 is subjected to slight vibration or stress change, the micro damping rubber blocks 2023 can effectively buffer, further enhancing the stability of the protective net structure 202. The outer side of the secondary wire mesh auxiliary layer 2022 is bonded to the inner side of the outer transition bonding layer 203 to ensure the overall stability of the protective net structure 202.

[0035] Specifically, such as Figure 2 , Figure 4 As shown, the inner liner tube 1 is made of polyetheretherketone material, and the thickness of the inner liner tube 1 is 8-12 mm.

[0036] Specifically, such as Figure 2 As shown, the inner transition adhesive layer 201 is made of modified polyurethane resin material, and the outer transition adhesive layer 203 is made of silicone-modified epoxy resin material.

[0037] In this embodiment: the inner liner tube 1 is made of polyetheretherketone material, which can effectively resist the erosion of the inner layer by acid, alkali, organic and inorganic media, ensuring that the transported material is pure and uncontaminated. In addition, the inner transition bonding layer 201 is made of modified polyurethane resin material, which tightly adsorbs the protective net structure 202 and adheres to the outside of the inner liner tube 1. This strong adsorption force ensures that the connection is stable and reliable when facing temperature changes and pressure fluctuations, ensuring the stability of the protective net structure 202 adhering to the outside of the inner liner tube 1, effectively preventing delamination, and enabling each layer to work together.

[0038] Specifically, such as Figure 3 As shown, the main wire mesh support layer 2021 is made of high-strength alloy steel wire, and the secondary wire mesh auxiliary layer 2022 is made of high-strength stainless steel wire.

[0039] Specifically, such as Figure 2As shown, the impact-resistant protective layer 204 is made of a composite material of polycarbonate and impact modifier, and the thickness of the impact-resistant protective layer 204 is 4-7 mm.

[0040] In this embodiment: the main wire mesh support layer 2021, made of high-strength alloy steel wire, and the secondary wire mesh auxiliary layer 2022, made of high-strength stainless steel wire, work together to ensure ultra-high radial support strength. In addition, the impact-resistant protective layer 204 is made of a composite material of polycarbonate and impact modifier, with a thickness of 4-7 mm. With its high elastic modulus, it can absorb and disperse impact energy instantly, effectively buffering the impact and resisting damage such as accidental impact, construction collision or ground subsidence, ensuring the continuity and stability of the inner liner pipe 1 during transportation.

[0041] Working Principle: During the use of the steel wire mesh reinforced pipe, various acidic, alkaline, organic, and inorganic media can be transported through the inner liner pipe 1. Its pipe wall effectively resists media erosion, ensuring that the transported substances are not contaminated and remain in a pure state, thus providing a reliable foundation for the entire transport process. Furthermore, the exceptionally smooth inner wall of the inner liner pipe 1 minimizes frictional resistance during media flow, allowing the media to move quickly and smoothly. This not only significantly improves transport efficiency but also substantially reduces energy consumption, laying a solid foundation for the stable and continuous operation of the inner liner pipe 1. Next, the inner transition bonding layer 201 plays a crucial connecting role. Made of modified polyurethane resin, it utilizes its strong adsorption properties to tightly adhere and bond the wire mesh structure 202. Fitted to the outside of the inner liner 1, this stable connection will not loosen regardless of fluctuations in ambient temperature or pressure inside the pipe. This effectively ensures the stability of the tight fit between the protective mesh structure 202 and the inner liner 1, completely eliminating delamination and creating favorable conditions for the coordinated operation of all components. The core components of the protective mesh structure 202 include a main wire mesh support layer 2021 and a secondary wire mesh auxiliary layer 2022. The main wire mesh support layer 2021 is carefully crafted from high-strength alloy steel wire and is tightly bonded to the outside of the inner transition bonding layer 201. Precisely positioned on the outside of the inner liner 1, it acts like a solid skeleton, providing strong radial support for the inner liner 1, effectively resisting radial pressure and preventing deformation of the inner liner 1. The secondary wire mesh auxiliary layer 2022... 022 is made of high-strength stainless steel wire and is laid on the outside of the main wire mesh support layer 2021. The two are laid in a 45-degree cross weave. This unique structure gives the net structure 202 excellent tensile, torsional, and shear resistance in all directions, easily coping with external forces from any direction. At the same time, at the inner intersection of the main wire mesh support layer 2021 and the secondary wire mesh auxiliary layer 2022, micro-damping rubber blocks 2023 are cleverly embedded. When the inner liner tube 1 is subjected to conditions such as fluid impact, slight vibration, or small stress changes, the micro-damping rubber blocks 2023 can quickly play a buffering role, absorbing and dissipating these unstable energies, further enhancing the overall stability of the net structure 202. Finally, the outer side of the secondary wire mesh auxiliary layer 2022 is firmly bonded to the inner side of the outer transition bonding layer 203, ensuring that the protective mesh structure 202 forms a stable whole. Meanwhile, the outer transition bonding layer 203, made of silicone-modified epoxy resin, plays a crucial role in connecting the protective mesh structure 202 with the impact-resistant protective layer 204. In the event of a sudden external impact, the impact-resistant protective layer 204, bonded to the outer side of the outer transition bonding layer 203, responds instantly. With its high elastic modulus, it can quickly absorb and disperse impact energy in the event of accidental impacts, construction collisions, or ground subsidence, effectively buffering external forces and ensuring that the inner liner pipe 1's transport process remains undisturbed, maintaining a continuous and stable state.Weather-resistant protective pipe 3, serving as the outermost robust protective layer, is made from ethylene-vinyl acetate copolymer blended and modified with UV absorbers, antioxidants, and other additives. Under long-term outdoor exposure or harsh weather conditions, the UV absorbers act like a shield, precisely blocking UV rays from corroding the pipe, while the antioxidants continuously inhibit oxidation reactions, effectively preventing aging and deterioration, protecting the internal structure, and significantly extending the overall service life of the steel wire mesh reinforced pipe.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
