At present, PE pipe is not good in high temperature resistance, which limits its use in high temperature environment. At the same time, the inner wall of PE pipe is prone to erosion, which not only shortens the service life of the pipeline, but also may affect the quality of the transported fluid. In addition, the bearing strength of PE pipe is relatively low, especially when used underground, it is easily affected by the pressure of road vehicles, resulting in damage or deformation.
[0003] Therefore, it is necessary to propose a PE pipe that is easy to assemble to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides Figure 1 - Figure 5 The PE pipe shown is easy to assemble, comprising a pipe body 1 , wherein the interior of the pipe body 1 has a plurality of reinforcing ribs 4 arranged equidistantly, which can effectively improve the bearing and pressure resistance of the pipe body 1 .
[0024] It should be noted that the reinforcing ribs 4 may be a wire frame structure, which is spliced to form a cylindrical mesh structure and then placed in a mold, and the pipe body 1 is formed by casting, which is a prior art and is not limited here.
[0025] The inner wall of the pipe body 1 is coated with a reinforcement layer 2 for enhancing the pipe body 1's resistance to high temperatures and chemical corrosion, thereby improving the overall performance and service life of the pipe body 1 .
[0026] Specifically, the reinforcement layer 2 includes a sintered epoxy powder coating 201, which is arranged on the inner wall of the pipe body 1. The sintered epoxy powder has the advantages of excellent insulation performance, high mechanical strength, resistance to temperature changes, resistance to chemical corrosion, etc., and can increase the high temperature resistance and chemical corrosion resistance of the pipe body 1.
[0027] Taking into account that the sintered epoxy powder coating 201 is easily separated from the surface of the structural layer as the use time increases, a microscopic convex-concave structural surface 101 is formed on the inner wall of the pipe body 1 by grinding before applying the sintered epoxy powder coating 201. The sintered epoxy powder coating 201 is coated and arranged on the microscopic convex-concave structural surface 101, which can ensure that there is more contact area between the sintered epoxy powder coating 201 and the pipe body 1, and the adhesion is higher and it is not easy to separate.
[0028] Furthermore, the surface of the fused epoxy powder coating 201 remains smooth, ensuring that the water inside the pipe body 1 flows smoothly.
[0029] The inner wall of the fused epoxy powder coating 201 is provided with a spiral structure 202 to guide the water flow in a spiral shape, thereby reducing the impact and damage to the inner wall of the pipe body 1.
[0030] In the prior art, when water flows inside the pipe body 1, the flow speed fluctuates within a range, sometimes fast and sometimes slow. When the water is sometimes fast and sometimes slow, for example, when a large amount of water flow at the rear impacts a small amount of water flow at the front, it will form an impact on the inner wall of the pipe body 1 or a water hammer phenomenon. Therefore, the spiral structure 202 guides the water so that the water flows in a spiral shape. When the water flow speed is unstable, the water will unload the force along the spiral flow, thereby reducing the impact on the inner wall of the pipe body 1 and increasing the service life of the pipe body 1.
[0031] During specific use, the spiral structure 202 may be a spiral groove or a spiral strip, which can be processed and set according to actual use requirements and is not limited here.
[0032] It should also be noted that a glass wool layer 203 is provided on the outside of the pipe body 1, which has excellent high temperature resistance and high temperature stability, and is suitable for a high temperature environment of 200°C. The glass wool layer 203 also has good thermal shock resistance and chemical stability, making it less susceptible to interference or influence from the surrounding environment. A polyurethane layer 204 is provided on the outer wall of the glass wool layer 203, and the inner wall of the polyurethane layer 204 is arranged in a strip shape; the inner wall of the polyurethane layer 204 is arranged in a strip shape, has good wear resistance and corrosion resistance, is light in weight, and has low installation and maintenance costs. The inner wall of the polyurethane layer 204 adopts a strip structure design, which can more effectively disperse and withstand external pressure, thereby improving the overall compressive strength of the pipe body 1.
[0033] The outer wall of the polyurethane layer 204 has multiple equidistantly arranged protrusions 3, which not only enhance the friction of the pipeline, but also improve the adhesion ability of the pipeline body 1 during transportation. If these protrusions 3 are worn during the transportation or installation of the pipeline, they will first contact and wear, thereby protecting the pipeline body 1 and further reducing the wear effect on the pipeline during transportation and installation.
