[0002] Stainless steel pipes are pipes made of stainless steel and are widely used in many fields due to their excellent corrosion resistance, high temperature resistance, and strength. They are commonly used for transporting liquids and gases, as well as as structural materials.

[0003] In the existing technology, if the surface of a steel pipe is in a humid environment after long-term use, it is easy for the steel pipe surface to be corroded and eroded, which can easily affect the structural strength of the steel pipe.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN103727316A) discloses a novel stainless steel pipe with a hollow tube body made of stainless steel; the outer wall of the tube body is covered with a flexible protective layer, and the inner wall of the tube body is attached with an inner lining layer made of plastic or iron; the flexible protective layer is made of plastic or rubber; the tube body is a seamless or welded tube. It has a simple structure, is easy to manufacture, and its corrosion resistance is even more outstanding when the application environment is suitable for plastic or iron.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, if the length of the steel pipe is insufficient, workers need to weld it before use, which is cumbersome and does not save workers' time. The installation and connection of the steel pipe are also inconvenient. Utility Model Content
