Description

Technical Field

[0001] The utility model relates to the technical field of PE solid wall pipes, and particularly relates to a heat-resistant, wear-resistant and highly tough PE solid wall pipe. Background Art

[0002] A PE solid wall pipe, fully known as a polyethylene solid wall pipe, is a pipe made of polyethylene material, which is characterized by having a complete solid wall structure without internal cavities or interlayers. PE solid wall pipes are usually manufactured by an extrusion process using raw materials such as high-density polyethylene (HDPE) or medium-density polyethylene (MDPE).

[0003] When in use, when a fluid flows through the pipe, the fluid will exert pressure on the inner wall of the pipe. After long-term use, the change in the fluid pressure inside the PE solid wall pipe will cause the PE solid wall pipe to deform. The deformation will change the shape and size of the pipe, affecting the flow state of the fluid. Severe deformation will cause the pipe to rupture, leading to safety accidents. In view of this, a heat-resistant, wear-resistant and highly tough PE solid wall pipe is designed. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a heat-resistant, wear-resistant and highly tough PE solid wall pipe, which solves the problems that after long-term use, the change in the fluid pressure inside the PE solid wall pipe will cause the PE solid wall pipe to deform, the deformation will change the shape and size of the pipe, affecting the flow state of the fluid, and severe deformation will cause the pipe to rupture, leading to safety accidents.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: A heat-resistant, wear-resistant and highly tough PE solid wall pipe, including a pipe body, the cross-section of the pipe body is elliptical, and a reinforcing layer is embedded in the middle of the pipe body;

[0006] The reinforcing layer includes a first steel wire and a second steel wire. The first steel wire is spirally wound clockwise along the circumference of the pipe body inside the pipe body, and the second steel wire is spirally wound counterclockwise along the circumference of the pipe body inside the pipe body. The first steel wire and the second steel wire are cross-fixed and connected.

[0007] Further, the wall thickness of the pipe body is 1.5 - 3.5 mm.

[0008] Further, an anti-ultraviolet layer is coated on the outer surface of the pipe body, and the thickness of the anti-ultraviolet layer is 0.1 - 0.3 mm.

[0009] Further, an outer wear-resistant layer is coated on the outer surface of the anti-ultraviolet layer, and the thickness of the outer wear-resistant layer is 0.1 - 0.3 mm.

[0010] Further, the inner wall of the pipe body is coated with an inner wear-resistant layer, and the thickness of the inner wear-resistant layer is 0.2 - 0.3 mm.

[0011] Further, a positioning line is provided on the outer surface of the pipe body along its length direction.

[0012] By means of the above technical solution, the present utility model provides a heat-resistant and wear-resistant high-toughness PE solid wall pipe, which has at least the following beneficial effects:

[0013] 1. A reinforcing layer is provided inside the pipe body. The reinforcing layer can effectively disperse and bear the fluid pressure inside the pipe body, thereby reducing the deformation caused by the internal pressure change, and enhancing the strength and stiffness of the PE solid wall pipe, enabling it to better resist the external forces encountered during transportation, installation, and use. Since it enhances the overall strength of the pipeline, the PE solid wall pipe can better maintain shape stability during thermal expansion and contraction, and extends the service life of the PE solid wall pipe.

[0014] 2. For this heat-resistant and wear-resistant high-toughness PE solid wall pipe, the cross-fixed connection of the first steel wire and the second steel wire forms a stable three-dimensional skeleton structure. This structure can significantly enhance the overall strength of the PE solid wall pipe, enabling the PE solid wall pipe to withstand greater pressure and tensile force.

[0015] 3. For this heat-resistant and wear-resistant high-toughness PE solid wall pipe, an anti-ultraviolet layer is provided on the pipe body. The anti-ultraviolet layer can effectively absorb and scatter the ultraviolet rays in sunlight, preventing the ultraviolet rays from directly irradiating on the PE solid wall pipe, enabling the PE solid wall pipe to better adapt to the outdoor environment. Especially in areas with sufficient sunlight and strong ultraviolet rays, it can extend the service life of the pipeline and reduce the maintenance and replacement costs caused by aging.

[0016] 4. For this heat-resistant and wear-resistant high-toughness PE solid wall pipe, an inner wear-resistant layer is added, which reduces the roughness of the inner wall of the PE solid wall pipe, makes the flow of the fluid in the PE solid wall pipe smoother, helps to reduce fluid resistance and energy loss, improves the transportation efficiency of the PE solid wall pipe, and enhances the wear resistance of the PE solid wall pipe. Especially when transporting fluids containing solid particles or with a high coefficient of friction, it can effectively reduce the wear of the inner wall of the PE solid wall pipe, thereby extending the overall service life of the PE solid wall pipe.

[0017] 5. For this heat-resistant and wear-resistant high-toughness PE solid wall pipe, an outer wear-resistant layer is added, which can absorb and disperse the external impact received by the PE solid wall pipe, reducing the risk of damage caused by the impact. Description of the Drawings

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , a heat-resistant and wear-resistant high-toughness PE solid wall pipe, including a pipe body 1. The cross-section of the pipe body 1 is elliptical. The elliptical cross-sectional shape can complete installation in a limited space more effectively than traditional circular pipes, especially in those occasions with limited space, such as narrow corridors or equipment-intensive areas. The elliptical pipe can make better use of space and reduce space occupation. Moreover, compared with circular pipes, the elliptical PE solid wall pipe has higher pressure resistance and corrosion resistance, can better withstand high fluid pressure, and improves the overall safety performance of the pipeline system.

[0026] The material of the pipe body 1 is made of high-temperature-resistant polyethylene material. The high-temperature-resistant polyethylene material has excellent thermal stability. In a high-temperature environment, the high-temperature-resistant polyethylene material can maintain the stability of its physical and chemical properties, is not prone to deformation, melting or generating harmful substances. This enables the PE solid wall pipe to still maintain its original shape and function under high-temperature conditions, ensuring the normal operation of the pipeline system. Secondly, the high-temperature-resistant polyethylene material also has good heat-aging resistance. The PE solid wall pipe made of high-temperature-resistant polyethylene material can effectively resist the influence of heat aging and maintain long-term stability and reliability. In addition, the high-temperature-resistant polyethylene material also has relatively high strength and toughness, which enables the PE solid wall pipe to maintain good compressive capacity while withstanding high temperatures, preventing problems such as pipeline rupture or leakage caused by temperature changes.

[0027] In the middle of the inside of the pipe body 1, a reinforcing layer 2 is embedded; the reinforcing layer 2 can effectively disperse and bear the fluid pressure inside the pipe body 1, thereby reducing the deformation caused by the internal pressure change, and enhancing the strength and stiffness of the PE solid wall pipe, enabling it to better resist the external forces encountered during transportation, installation, and use. Due to its enhancement of the overall strength of the pipeline, the PE solid wall pipe can better maintain shape stability during thermal expansion and contraction, extending the service life of the PE solid wall pipe.

[0028] The reinforcing layer 2 includes a first steel wire 201 and a second steel wire 202. The first steel wire 201 is spirally wound clockwise along the circumferential direction of the pipe body 1 inside the pipe body 1, and the second steel wire 202 is spirally wound counterclockwise along the circumferential direction of the pipe body 1 inside the pipe body 1. The first steel wire 201 and the second steel wire 202 are cross-fixed and connected. The cross-fixed connection of the first steel wire 201 and the second steel wire 202 forms a stable three-dimensional skeleton structure, which can significantly enhance the overall strength of the PE solid wall pipe, enabling the PE solid wall pipe to withstand greater pressure and tensile force. Since the first steel wire 201 and the second steel wire 202 are wound in a spiral manner inside the pipe body 1, they can effectively absorb and disperse the forces from different directions, thereby significantly improving the anti-deformation ability of the PE solid wall pipe, enabling the PE solid wall pipe to maintain better shape stability when subjected to external forces or internal pressure changes.

[0029] The wall thickness of the pipe body 1 is 1.5 - 3.5 mm. The appropriate wall thickness can be selected according to specific application scenarios and requirements. For example, in occasions where greater pressure or external force needs to be borne, a thicker wall thickness can be selected; while in some occasions with higher cost requirements, a thinner wall thickness can be selected.

[0030] The outer surface of the pipe body 1 is coated with an anti-ultraviolet layer 3. The material of the anti-ultraviolet layer 3 is cross-linked polyethylene, and the thickness of the anti-ultraviolet layer 3 is 0.1 - 0.3 mm. The anti-ultraviolet layer 3 can effectively absorb and scatter the ultraviolet rays in sunlight, preventing the ultraviolet rays from directly irradiating the PE solid wall pipe. Ultraviolet rays are a kind of electromagnetic radiation with higher energy, and long-term irradiation will cause the pipeline material to age, discolor, and become brittle, thereby reducing the service life of the PE solid wall pipe. The anti-ultraviolet layer 3 can protect the PE solid wall pipe from the damage of ultraviolet rays and maintain its good physical and chemical properties. Secondly, by coating the anti-ultraviolet layer 3, the PE solid wall pipe can better adapt to the outdoor environment, especially in areas with sufficient sunlight and strong ultraviolet rays, which can extend the service life of the pipeline and reduce the maintenance and replacement costs caused by aging. In addition, the anti-ultraviolet layer 3 can also improve the weather resistance of the PE solid wall pipe, enabling it to maintain stable performance under different climate conditions. Whether in the hot summer or the cold winter, the anti-ultraviolet layer 3 can provide additional protection for the pipeline to ensure its normal operation.

[0031] The outer surface of the ultraviolet-resistant layer 3 is coated with an outer wear-resistant layer 5, and the thickness of the outer wear-resistant layer 5 is 0.1 - 0.3 mm. It can absorb and disperse the external impact received by the PE solid-wall pipe, reducing the risk of damage caused by impact.

[0032] The inner wall of the pipe body 1 is coated with an inner wear-resistant layer 4, and the thickness of the inner wear-resistant layer 4 is 0.2 - 0.3 mm. This reduces the roughness of the inner wall of the PE solid-wall pipe, making the flow of fluid in the PE solid-wall pipe smoother, helping to reduce fluid resistance and energy loss, improving the conveying efficiency of the PE solid-wall pipe, and enhancing the wear resistance of the PE solid-wall pipe. Especially when conveying fluids containing solid particles or with a high coefficient of friction, it can effectively reduce the wear of the inner wall of the PE solid-wall pipe, thereby extending the overall service life of the PE solid-wall pipe.

[0033] The outer surface of the pipe body 1 is provided with a positioning line 6 along its length direction. The positioning line 6 provides a clear reference mark for the installation of the PE solid-wall pipe. During the installation process, construction workers can quickly and accurately determine the position and direction of the PE solid-wall pipe according to the positioning line 6, ensuring the alignment and connection of the PE solid-wall pipe with other components or structures are accurate, improving the installation efficiency, reducing installation errors, and ensuring the stability and reliability of the entire pipeline system.
