[0002] The main material of steel-plastic composite chemical pipes is ultra-high molecular weight polyethylene (UHMW-PE). UHMW-PE is a thermoplastic engineering plastic with an average molecular weight greater than 2 million, polymerized from ethylene and butadiene monomers under the action of a catalyst. It boasts superior comprehensive performance, with wear resistance, low-temperature resistance, corrosion resistance, self-lubrication, and impact resistance being the highest among all plastics. Its wear resistance surpasses that of polytetrafluoroethylene (PTFE), nylon, and carbon steel, allowing it to operate continuously in conditions ranging from -269 degrees Celsius to +80 degrees Celsius, earning it the title of "amazing plastic."

[0027] In this embodiment, the outer protective cylinder 7 is a rigid pipe 1. The outer protective cylinder 7 can protect the outside of the pipe 1 and reduce the weathering of the exterior of the pipe 1.

[0028] like Figures 1-3 As shown, the built-in pipe is fitted to the inner wall of the pipe 1. The built-in pipe includes a fitting ring 3 and a fitting splicing plate 4. Fitting rings 3 are fitted to both sides of the inside of the pipe 1. The fitting splicing plate 4 is set inside the pipe 1. There are multiple fitting splicing plates 4. Multiple fitting splicing plates 4 are spaced apart on one side of the fitting ring 3. The fitting splicing plates 4 on the fitting rings 3 on both sides of the inside of the pipe 1 are cross-fitted.

[0029] like Figure 3 As shown, a U-shaped sealing gasket 5 is fitted on the outside of the interlocking splicing plate 4 to seal the gap between adjacent interlocking splicing plates 4.

[0030] The interlocking splicing plates 4 are interlocked to form the internal pipe of the pipe 1, which allows for easy replacement of the internal wall components of the pipe 1 in the event of internal cracks. In other words, by replacing the damaged interlocking splicing plates 4, the damaged parts of the pipe 1 can be repaired in a timely manner.

[0031] like Figures 1-3 As shown, the sealing assembly includes a connecting ring 2, a first sealing ring 6, and a second sealing ring 15. Connecting rings 2 are provided on both sides of the pipe opening 1. One end of the connecting ring 2 is fixedly connected to the insertion ring 3. The second sealing ring 15 is sleeved on the outside of the insertion ring 3 and is located between the connecting ring 2 and the pipe 1. The two sides of the second sealing ring 15 are respectively attached to the connecting ring 2 and the pipe 1. The first sealing ring 6 is attached to the other side of the connecting ring 2.

[0032] In this embodiment, the other side of the first sealing ring 6 is fitted with the connecting ring 2 at the side end of another adjacent pipe 1.

[0033] The second sealing ring 15 and the first sealing ring 6 can seal both sides of the connecting ring 2, thereby sealing both sides of the pipe 1.

[0038] The working principle of this utility model is as follows: In use, the interlocking splicing plates 4 on both sides are interlocked to form the internal pipe of the pipe 1. In the case of internal cracks in the pipe 1, the interlocking splicing plates 4 can be used to protect the pipe 1 and repair the damaged parts of the pipe 1 in a timely manner. The second sealing ring 15 and the first sealing ring 6 can be used to seal both sides of the connecting ring 2, thereby sealing both sides of the pipe 1. The clamp 8 can be used to fix the two pipes 1 on both sides in the sealed state and connect the two pipes 1 on both sides. The outermost outer protective cylinder 7 protects the outside of the pipe 1 and reduces the weathering of the outer facade of the pipe 1. When fixing, the interlocking block 9 is inserted into the interlocking groove 10, and the clamp 8 is used to fix the two outer protective cylinders 7, thereby realizing the auxiliary connection and fixation of the pipe 1.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
