[0002] Seamless stainless steel pipe is a long, seamless steel strip with a hollow cross-section. Materials and Classification: Seamless stainless steel pipe is primarily made of stainless steel and can be categorized by rolling method into hot-rolled, hot-extruded, and cold-drawn (rolled) stainless steel pipe. Based on the metallographic structure of the stainless steel, it can also be classified into semi-ferritic and semi-martensitic stainless steel seamless pipes, martensitic stainless steel seamless pipes, austenitic stainless steel seamless pipes, and austenitic-ferritic stainless steel seamless pipes.

[0003] Although the seamless steel pipe in the existing technology has an integrally formed structure and can meet the strength standards, when transmitting fluid or gas with fine particles inside, the inside is easily scratched and causes unnecessary wear, which can easily shorten the service life of the device. Therefore, a high-strength, wear-resistant seamless stainless steel pipe is needed to improve this problem. Utility Model Content

[0007] Preferably, connecting flanges are fixedly provided at both ends of the steel pipe body, and mounting holes are provided on the outer surface of the connecting flanges. The two steel pipe bodies can be conveniently installed together through the connecting flanges and the mounting holes. After the two steel pipe bodies are installed together, the sealing rings can be squeezed and the first sealing ring and the second sealing ring are respectively embedded in the first sealing groove and the second sealing groove, thereby ensuring the sealing between the plastic lining and the steel pipe body.

[0008] Preferably, the plastic lining is made of polyethylene plastic material, which has good wear resistance and impact resistance, and can replace the inner side wall of the steel pipe body to accept the impact of impurities in the fluid, while the steel pipe body can ensure the overall structural strength of the device; and this device can also use polyvinyl chloride as needed, which has good chemical corrosion resistance.

[0009] Preferably, the plastic liner is fixed inside the steel pipe body by interference fit, so that the plastic liner is tightly embedded in the steel pipe body through interference fit, thereby ensuring the sealing between the plastic liner and the steel pipe body.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model adds an additional protective structure inside the traditional steel pipe body. This protective structure is a plastic lining. The plastic lining replaces the steel pipe body in contact with impurities inside the fluid. This can significantly improve the corrosion resistance and wear resistance of traditional seamless stainless steel pipes, thereby increasing the service life of traditional seamless stainless steel pipes.

[0012] 2. When the utility model is used, the two steel pipe bodies can be conveniently installed together through the connecting flange and the mounting hole. After the two steel pipe bodies are installed together, the sealing ring can be squeezed and the first sealing ring and the second sealing ring are respectively embedded in the first sealing groove and the second sealing groove, thereby ensuring the sealing between the plastic lining and the steel pipe body.
