Description

Technical Field

[0001] This utility model belongs to the field of pipe technology, specifically, it relates to a high molecular weight polyethylene pipe. Background Technology

[0002] High-molecular-weight polyethylene (HMWPE) pipes have excellent wear resistance and impact resistance, capable of withstanding heavy impacts and friction. They are highly resistant to acids, alkalis, and salts, do not scale or absorb water, and possess self-lubricating and non-stick properties, making them less prone to dirt adhesion and moisture absorption. Their low coefficient of friction reduces transport resistance, and their service life of up to 50 years meets long-term usage requirements. However, they have poor heat resistance and are easily affected by high temperatures and ultraviolet radiation, leading to changes in chemical properties and performance degradation. Furthermore, their low stiffness and strength make them susceptible to deformation and plastic deformation under high loads and stresses.

[0003] Chinese patent CN216618970U discloses a novel corrosion-resistant high-molecular-weight polyethylene pipe, comprising a corrosion-resistant pipe body, a threaded connecting pipe threaded to the inner wall of the corrosion-resistant pipe body, a fixed connecting pipe fixedly connected to the outer surface of the front end of the threaded connecting pipe, an annular mounting component provided on the outer surface of the front end of the fixed connecting pipe, a filter screen fixedly connected to the inner wall of the annular mounting component, a circular rotating shaft rotatably connected to the outer surface of the rear end of the filter screen, and a connecting rod fixedly connected to the outer wall of the circular rotating shaft. This design allows for the filtration of impurities in flowing water, and when the filter screen becomes clogged, it can be cleaned by the cooperation of a brush plate and the circular rotating shaft, facilitating improved filter screen throughput and enhancing the practicality of the high-molecular-weight polyethylene pipe. However, its heat resistance is poor, making it susceptible to the effects of high temperatures and ultraviolet radiation, leading to changes in chemical properties and performance degradation. Furthermore, its rigidity and strength are low, making it prone to deformation and plastic deformation under high loads and high stresses.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high molecular weight polyethylene pipe to solve the problems of poor heat resistance of existing high molecular weight polyethylene pipes, which are easily affected by high temperature and ultraviolet light, resulting in changes in chemical properties and performance decline. At the same time, the pipes have low stiffness and strength and are prone to deformation and plastic deformation under high load and high stress.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-molecular-weight polyethylene pipe, including a pipe body. The inner wall of the pipe body is bonded with a reinforcing layer. The reinforcing layer is composed of interwoven transverse reinforcing filaments and longitudinal reinforcing filaments. Both the transverse and longitudinal reinforcing filaments are composed of integrally extruded irregular glass fiber filaments and multiple carbon fiber monofilaments. The number of carbon fiber monofilaments is three. The three carbon fiber monofilaments are spirally wound on the irregular glass fiber filaments. The outer wall of the irregular glass fiber filaments is integrally formed with three grooves adapted to the carbon fiber monofilaments. The three carbon fiber monofilaments are bonded to the three grooves.

[0007] Furthermore, the inner wall of the reinforcing layer is integrally formed with an inner tube.

[0008] Furthermore, both the inner tube and the tube body are made of high molecular weight polyethylene.

[0009] Furthermore, the outer wall of the pipe body is integrally formed with an antifreeze layer, and the antifreeze layer is made of rubber and plastic sponge.

[0010] Furthermore, the outer wall of the antifreeze layer is integrally formed with a protective layer, the protective layer being made of glass cloth, which is wrapped around the outer wall of the antifreeze layer.

[0011] Furthermore, the nominal diameter of the inner tube is 6 mm, and the wall thickness is 2.0 mm.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0013] 1. In this utility model, the irregularly shaped glass fiber filament has the characteristics of being lightweight and high-strength, corrosion-resistant, wear-resistant, having excellent high-temperature performance, and being easy to process. Carbon fiber monofilament is a high-performance inorganic non-metallic material with the effects of reinforcing material, electrical insulation, and thermal insulation. Because three carbon fiber monofilaments are spirally wound on the irregularly shaped glass fiber filament and bonded to each other through grooves, the toughness of the transverse and longitudinal reinforcing filaments is increased and they are not easy to break. This makes the reinforcing layer composed of the interwoven transverse and longitudinal reinforcing filaments have good bending stiffness and strength, and can bear greater loads. This avoids the problem that existing high-molecular polyethylene pipes are prone to deformation and plastic deformation under high load and high stress.

[0014] 2. In this utility model, by setting an inner tube, the high molecular weight polyethylene pipe is composed of two pipes, an inner and an outer one, thereby increasing the rigidity and strength of the high molecular weight polyethylene pipe, enhancing the pipe body's resistance to deformation and stability, and improving the pipe's bending stiffness. This also avoids the problem of deformation and plastic deformation that existing high molecular weight polyethylene pipes are prone to under high load and high stress, thus extending the service life of the pipe body.

[0027] Existing high-molecular-weight polyethylene pipes have poor heat resistance and are easily affected by high temperatures and ultraviolet radiation, leading to changes in chemical properties and a decline in performance. At the same time, they have low stiffness and strength and are prone to deformation and plastic deformation under high loads and high stresses.

[0028] Depend on Figure 1-5 This utility model provides a high molecular weight polyethylene pipe.

[0029] Specifically, by Figure 2-5 The pipe body 1 is provided. The inner wall of the pipe body 1 is bonded with a reinforcing layer 2. The reinforcing layer 2 is composed of interwoven transverse reinforcing filaments 3 and longitudinal reinforcing filaments 4. Both the transverse reinforcing filaments 3 and the longitudinal reinforcing filaments 4 are composed of integrally extruded irregular glass fiber filaments 5 and multiple carbon fiber monofilaments 6. There are three carbon fiber monofilaments 6, which are spirally wound on the irregular glass fiber filaments 5. The outer wall of the irregular glass fiber filaments 5 is integrally formed with three grooves 7 that are adapted to the carbon fiber monofilaments 6. The three carbon fiber monofilaments 6 are bonded to the three grooves 7.

[0030] In this invention, the irregularly shaped glass fiber filament 5 is lightweight and high-strength, corrosion-resistant, wear-resistant, has excellent high-temperature performance, and is easy to process. The carbon fiber monofilament 6 is a high-performance inorganic non-metallic material with the effects of reinforcing material, electrical insulation, and thermal insulation. Because three carbon fiber monofilaments 6 are spirally wound on the irregularly shaped glass fiber filament 5 and bonded to each other through the groove 7, the toughness of the transverse reinforcing filament 3 and the longitudinal reinforcing filament 4 is increased, and they are not easy to break. This makes the reinforcing layer 2 composed of the interwoven transverse reinforcing filament 3 and longitudinal reinforcing filament 4 have good bending stiffness and strength, and can bear greater loads. This avoids the problem that existing high-molecular polyethylene pipes are prone to deformation and plastic deformation under high load and high stress.

[0031] Furthermore, as a specific embodiment of this utility model, this utility model provides a high molecular weight polyethylene pipe.

[0032] Specifically, by Figure 1 and 5 It is given that the inner wall of the reinforcing layer 2 is integrally formed with an inner tube 8.

[0033] In this invention, by setting an inner tube 8, the high molecular weight polyethylene pipe is composed of two tubes, an inner and an outer tube, thereby increasing the rigidity and strength of the high molecular weight polyethylene pipe and avoiding the problem of deformation and plastic deformation that existing high molecular weight polyethylene pipes are prone to under high load and high stress.

[0034] Furthermore, as a specific embodiment of this utility model, this utility model provides a high molecular weight polyethylene pipe.

[0035] Specifically, by Figure 1 and 5 It is stated that both the inner tube 8 and the tube body 1 are made of high molecular weight polyethylene.

[0036] In this invention, ultra-high molecular weight polyethylene (UHMWPE) has a low coefficient of friction and can self-lubricate. In harsh environments with a lot of mud and sand, the UHMWPE pipe can move freely, ensuring that related workpieces will not be worn or scratched. It is non-toxic and odorless, and its wear resistance is 4-7 times higher than that of ordinary steel pipes and 27.3 times that of stainless steel. Due to its low coefficient of friction and non-polarity, it has a non-adhesive surface and is resistant to low temperatures, allowing it to be stored for a long time between -269°C and 80°C. Because there are very few unsaturated molecules in the molecular chain, it has high stability, so its aging rate is particularly slow. Within a certain temperature and concentration range, many corrosive media and organic solvents are also helpless against it, thus extending the service life of the inner tube 8 and the pipe body 1.

[0037] Furthermore, as a specific embodiment of this utility model, this utility model provides a high molecular weight polyethylene pipe.

[0038] Specifically, by Figure 5 It is given that the outer wall of the pipe body 1 is integrally formed with an antifreeze layer 9, and the material of the antifreeze layer 9 is rubber and plastic sponge.

[0039] In this invention, the rubber-plastic sponge has a low thermal conductivity, enabling it to achieve the same insulation effect as other insulation materials while being more than half the thickness under the same external conditions. This saves space after pipe installation and reduces investment. It also has good flame retardant properties, is exceptionally soft, and is easy and convenient to install. It can be installed by slipping it on or by cutting it lengthwise and then gluing it together. Because the rubber-plastic sponge has high elasticity, it can minimize the vibration and resonance of chilled and hot water pipes during use. It is also safe to use, will not harm human health, will not irritate the skin, and is resistant to acids and alkalis, thus effectively protecting the pipe body 1.

[0040] Furthermore, as a specific embodiment of this utility model, this utility model provides a high molecular weight polyethylene pipe.

[0041] Specifically, by Figure 1 and 5 It is shown that the outer wall of the antifreeze layer 9 is integrally formed with a protective layer 10, the material of the protective layer 10 is glass cloth, and the glass cloth is wrapped around the outer wall of the antifreeze layer 9.

[0042] In this invention, the glass cloth has a wide range of applications and can be used to protect various pipes and equipment, such as water pipes, gas pipes, oil, gas, and water pressure vessels and steel storage tanks. It has strong resistance to acids and alkalis and corrosion and can be used in a variety of harsh environmental conditions, such as high humidity, high temperature, and high pressure. At the same time, the glass cloth has dense and uniform fiber distribution, good tensile properties, and high tensile strength, which can effectively prevent water and moisture from seeping into the pipe, thereby extending the service life of the pipe. The glass cloth is flexible and easy to cut, paste, fold, and wrap around the outer wall of the antifreeze layer 9, making construction convenient and effectively protecting the antifreeze layer 9 and ensuring its antifreeze effect.

[0043] Furthermore, as a specific embodiment of this utility model, this utility model provides a high molecular weight polyethylene pipe.

[0044] Specifically, by Figure 5 It is given that the nominal diameter of the inner tube 8 is 6 mm and the wall thickness is 2.0 mm.

[0045] In this invention, by setting an inner tube 8, the thickness of the pipe body 1 is increased, thereby enhancing the pipe body 1's resistance to deformation and stability, and thus improving the pipe's bending stiffness.

[0046] Working principle:

[0047] The irregularly shaped glass fiber filament 5 is lightweight, high-strength, corrosion-resistant, wear-resistant, has excellent high-temperature performance, and is easy to process. The carbon fiber monofilament 6 is a high-performance inorganic non-metallic material with the effects of reinforcement, electrical insulation, and thermal insulation. Because three carbon fiber monofilaments 6 are spirally wound on the irregularly shaped glass fiber filament 5 and bonded to each other through the groove 7, the toughness of the transverse reinforcing filament 3 and the longitudinal reinforcing filament 4 is increased and they are not easy to break. This gives the reinforcing layer 2, composed of the interwoven transverse reinforcing filament 3 and longitudinal reinforcing filament 4, good bending stiffness and strength, which can bear greater loads. This avoids the problem of deformation and plastic deformation that existing high molecular weight polyethylene pipes are prone to under high load and high stress.

[0048] By incorporating an inner tube 8, this high-molecular-weight polyethylene (HMWPE) pipe is composed of two tubes, an inner and an outer tube, thereby increasing its rigidity and strength. This enhances the pipe body 1's resistance to deformation and stability, improving its bending stiffness. Furthermore, it avoids the problem of deformation and plastic deformation that existing HMWPE pipes are prone to under high loads and stresses. HMWPE has a low coefficient of friction and self-lubrication, allowing for free movement even in harsh environments with abundant sediment, ensuring that related workpieces are not worn or damaged. It is non-toxic, odorless, and has wear resistance 4-7 times higher than ordinary steel pipes and 27.3 times higher than stainless steel. Due to its low coefficient of friction and non-polarity, it has a non-adhesive surface and is resistant to low temperatures, allowing for long-term storage between -269℃ and 80℃. Because its molecular chain contains very few unsaturated molecules, it has high stability and therefore ages very slowly. Within a certain temperature and concentration range, many corrosive media and organic solvents are ineffective against it, thus extending the service life of the inner tube 8 and the pipe body 1.

[0049] Rubber and plastic foam has a low thermal conductivity, allowing it to achieve the same insulation effect with less than half the thickness of other insulation materials under the same external conditions. This saves space after pipe installation and reduces investment. It also has good flame retardant properties, is exceptionally soft, and is easy to install. It can be installed by slipping it on or by cutting it lengthwise and then gluing it together. Because of its high elasticity, rubber and plastic foam minimizes vibration and resonance in chilled and hot water pipes during use. It is safe to use, does not harm human health, does not irritate the skin, and is resistant to acids and alkalis, exhibiting superior performance and effectively protecting the pipe itself. 1.

At the same time, the fiber cloth has dense and uniform fiber distribution, good tensile properties and high tensile strength, which can effectively prevent water and moisture from penetrating into the pipeline, thereby extending the service life of the pipeline. The fiber cloth is flexible and easy to cut, paste and fold, and wrap around the outer wall of the antifreeze layer 9, which is convenient for construction and effectively protects the antifreeze layer 9, ensuring the antifreeze effect of the antifreeze layer 9.
