The first main layer 201 is the middle layer of the inner wall layer 2. The first reinforcing layer 202 is disposed below the first main layer 201, and the inner coating layer 203 is disposed below the first reinforcing layer 202. A first fusion layer 204 is disposed between the bottom surface of the first main layer 201 and the top surface of the first reinforcing layer 202.

[0022] The pipe body 1 comprises an inner wall layer 2 and an outer wall layer 3. The pipe body 1 is a corrugated pipe. The thickness of the inner wall layer 2 is greater than the thickness of the outer wall layer 3. A connecting layer 4 is provided between the inner wall layer 2 and the outer wall layer 3. The inner wall layer 2, the outer wall layer 3, and the connecting layer 4 form the overall structure of the pipe body 1. The outer wall layer 3 includes a second main layer 301, a second reinforcing layer 302, a third fusion layer 303, and a fourth fusion layer 304. The second main layer 301 is the middle layer of the outer wall layer 3. Above the second main layer 301, there is a... The top surface of the second reinforcing layer 302 and the bottom surface of the second main layer 301 are bonded together by the third fusion layer 303.

[0023] The working principle of this practical application is as follows:

[0024] Refer to the instruction manual appendix Figures 1-4For this type of impact-resistant PVC hose, the hose features a multi-layered structure, including an inner wall layer 2, an outer wall layer 3, and a connecting layer 4, as well as reinforcing and fusion layers within each layer. This multi-layered structure effectively disperses and resists impact forces, protecting the fluid or cables inside from damage. The inner wall layer 2 and outer wall layer 3 are primarily made of polyvinyl chloride resin, which possesses flexibility, stability, and pressure resistance. Meanwhile, the reinforcing layer uses nitrile rubber, further enhancing the hose's strength. With its flexibility and impact resistance, the modified polyvinyl chloride coating, used as an inner coating material, not only improves the hose's impact resistance but also ensures that the fluid or cables inside the hose are not corroded or damaged. The fusion layer, including the first fusion layer 204, the second fusion layer 205, the third fusion layer 303, and the fourth fusion layer 304, plays a crucial role in the hose structure. They are firmly bonded together by a special adhesive, ensuring the integrity and stability of the hose. This bonding method not only improves the hose's tear resistance but also makes it less prone to interlayer separation when subjected to external forces.

[0025] Before installing PVC hoses, first check that the hoses are intact and free from cracks, breaks, or deformation. Select the appropriate hose length and specifications according to actual needs to ensure that they meet the usage requirements. During use, avoid subjecting the hoses to excessive external impact or compression to prevent damage to their structure or performance. This impact-resistant PVC hose, through its unique multi-layer structure and high-quality material selection, ensures its stability and durability in various harsh environments.
