Description

Technical Field

[0001] This utility model relates to the field of stainless steel water pipe technology, specifically a high-strength stainless steel water pipe. Background Technology

[0002] Stainless steel water pipes are pipe products made primarily of stainless steel and used to transport fluids such as water. They are widely used in various fields such as construction, industry, and municipal engineering.

[0003] A Chinese patent (CN205654984U) discloses a stainless steel water pipe, including a delivery pipe and a connecting pipe. The outer diameter of the delivery pipe is adapted to the inner diameter of the connecting pipe. One end of the delivery pipe connected to the connecting pipe has an inclined inlet surface. Two annular protrusions are provided on the outer circumference of the pipe wall near the inlet surface, forming an annular groove between the two protrusions. The connecting pipe includes a connecting portion that seals with the delivery pipe and a reinforcing portion integrally formed with the connecting portion and tapering inwards radially. An annular groove matching the annular groove of the delivery pipe is provided on the inner circumference of the pipe wall at the connecting portion. A sealing strip is provided between the annular groove of the delivery pipe and the annular groove of the connecting pipe. This stainless steel water pipe is easy to process, manufacture, and install, has high tensile strength, and is energy-saving and environmentally friendly.

[0004] Currently, stainless steel water pipes on the market perform poorly in terms of pressure resistance, and the pipe body is prone to deformation when subjected to certain pressure. This deformation not only shortens the service life of the water pipe but may also cause a series of subsequent problems, increasing maintenance and replacement costs. Furthermore, due to the lack of effective structural reinforcement design during use and transportation, stainless steel water pipes are weak in resisting external pressure, and are easily deformed by even slight external forces, thus seriously affecting the normal use of the water pipes and causing numerous inconveniences and potential risks to users. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength stainless steel water pipe to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength stainless steel water pipe, comprising: a stainless steel pipe body, a spiral support strip on the inner wall of the stainless steel pipe body, annular reinforcing ribs on the outer wall of the stainless steel pipe body, a plurality of annular reinforcing ribs, the plurality of annular reinforcing ribs being arranged at equal intervals on the outer wall of the stainless steel pipe body, a fiber cloth wrapped around the outer wall of the stainless steel pipe body, an inner sleeve on the outer side of the fiber cloth, an outer sheath on the outer side of the inner sleeve, and a buffer adhesive filling the space between the outer sheath and the inner sleeve.

[0007] Furthermore, a sealing sleeve is provided on the outer side of the inner sleeve, and the buffer rubber is located between the outer sleeve and the sealing sleeve.

[0008] Furthermore, the stainless steel pipe body is provided with flanges at both ends, and mounting holes are provided inside the flanges. Reinforcing ribs are provided between the flanges, and there are multiple reinforcing ribs, which are evenly arranged circumferentially between the flanges.

[0009] Furthermore, the fiber cloth is either glass fiber cloth or carbon fiber cloth, and resin adhesive is provided on the side of the fiber cloth near the stainless steel tube body.

[0010] Furthermore, the inner sleeve is a PE sleeve, and the sealing sleeve is made of rubber.

[0011] Furthermore, the outer sheath is made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the design of spiral support bars, annular reinforcing ribs, and fiber cloth, achieves a continuous spiral reinforcement system when stainless steel water pipes are used. The spiral support bars are tightly bonded to the pipe wall, forming a continuous spiral reinforcement system that enhances the overall pressure resistance of the pipe. The annular reinforcing ribs can suppress local indentation of the pipe wall under high pressure. The high-strength fiber cloth is wrapped around the outside of the pipe with resin adhesive to form a protective layer, enhancing the pipe's pressure resistance and corrosion resistance. The inner sleeve, sealing sleeve, buffer rubber, and outer sheath resist external impact, corrosion, and wear, while simultaneously improving the pipe's pressure resistance and bending resistance, ensuring the safety and reliability of the stainless steel water pipe.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a high-strength stainless steel water pipe, comprising: a stainless steel pipe body 1, with a spiral support strip 2 provided on the inner wall of the stainless steel pipe body 1, the spiral support strip 2 being tightly integrated with the pipe wall of the stainless steel pipe body 1 to form a continuous spiral reinforcement system. This structure can disperse the radial or axial force on the pipe into a shear force in the spiral direction, thereby significantly improving the overall pressure resistance of the pipe and reducing the risk of pipe wall deformation under high pressure.

[0022] The outer wall of the stainless steel pipe body 1 is provided with annular reinforcing ribs 4. There are multiple annular reinforcing ribs 4, which are arranged at equal intervals on the outer wall of the stainless steel pipe body 1. The annular reinforcing ribs 4 can suppress local indentation of the pipe wall under high pressure. By arranging them at equal intervals, the stress is evenly distributed on the pipe wall, reducing the risk of cracking caused by stress concentration and further improving the pressure resistance of the pipeline.

[0023] The outer wall of the stainless steel pipe body 1 is wrapped with fiber cloth 5, which is tightly wrapped with resin adhesive to form an additional protective layer. This not only enhances the pipe's pressure resistance but also effectively resists the erosion of external corrosive media, extending the pipe's service life. An inner sleeve 6 is provided outside the fiber cloth 5. The inner sleeve 6 acts as a protective layer for the fiber cloth 5, further enhancing the pipe's structural strength and preventing damage to the fiber cloth 5 from external impacts. Simultaneously, the inner sleeve 6 also provides some heat insulation and sound insulation. An outer sheath 9 is provided outside the inner sleeve 6, with a buffer adhesive 8 filling the space between the outer sheath 9 and the inner sleeve 6. The buffer adhesive 8, filling the space between the outer sheath 9 and the inner sleeve 6, acts as a buffer and shock absorber, absorbing external impact forces and reducing damage to the pipe. The outer sheath 9 provides additional mechanical protection, preventing physical damage to the pipe.

[0024] A sealing sleeve 7 is provided on the outside of the inner sleeve 6, and a buffer rubber 8 is located between the outer sheath 9 and the sealing sleeve 7. The sealing sleeve 7 fits tightly against the outside of the inner sleeve 6, forming a sealing system together with the buffer rubber 8 and the outer sheath 9. This not only enhances the sealing performance of the pipeline and prevents leakage of the buffer rubber 8, but also further resists external corrosion and wear, improving the overall durability of the pipeline.

[0025] The stainless steel pipe body 1 has flanges 3 at both ends. Each flange 3 has internal mounting holes. As a crucial component for pipe connection, the flange 3 connects to other pipes or equipment through these mounting holes, ensuring the stability and sealing of the pipeline system. The design of the flange 3 also facilitates pipe installation and maintenance. Multiple reinforcing ribs 10 are evenly distributed circumferentially between the flanges 3. This circumferential distribution of the reinforcing ribs 10 enhances the pipe's strength and reduces the risk of deformation under external forces. This helps maintain the overall stability of the pipeline system and extends its service life.

[0026] The fiber cloth 5 can be either glass fiber cloth or carbon fiber cloth, and resin adhesive is applied to the side of the fiber cloth 5 closest to the stainless steel pipe body 1. Glass fiber cloth or carbon fiber cloth is characterized by high strength, lightweight, and corrosion resistance. It is tightly bonded to the outer wall of the stainless steel pipe body 1 with resin adhesive, forming a robust protective layer. This not only enhances the pipe's pressure resistance but also effectively resists external corrosion and wear, ensuring the pipe's safety and reliability.

[0027] The inner sleeve 6 is a PE sleeve, and the sealing sleeve 7 is made of rubber. The PE sleeve, as the inner sleeve 6, features good flexibility, excellent low-temperature resistance, and high chemical stability, enabling it to adapt to various complex environments. The rubber sealing sleeve 7 provides good sealing and elasticity, ensuring the sealing and stability of the piping system.

[0028] The outer sheath 9 is made of stainless steel. The thin-walled stainless steel outer sheath 9 possesses excellent corrosion resistance and high strength, enabling it to withstand long-term erosion and impact from the external environment, protecting the pipeline system from damage. At the same time, stainless steel also offers good aesthetics and durability, enhancing the overall quality of the pipeline.

[0029] When stainless steel water pipes are used, the spiral support strips are tightly bonded to the pipe wall to form a continuous spiral reinforcement system, which improves the overall pressure resistance of the pipe. The annular reinforcing ribs 4 can suppress local indentation of the pipe wall under high pressure. The high-strength fiber cloth 5 is wrapped with resin glue on the outside of the pipe to form a protective layer, which improves the pressure resistance and corrosion resistance of the pipe. The inner sleeve, sealing sleeve, buffer rubber and outer sheath 9 resist external impact, corrosion and wear, while improving the pressure resistance and bending resistance of the pipe, ensuring the safety and reliability of stainless steel water pipes.

[0030] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
