Stainless steel pipe is a material with good seawater corrosion resistance, but in practical engineering application, various corrosion damages often occur in the stainless steel connection, especially in the welding area, resulting in great losses. After adopting the new welding process, the microstructure and properties of the weld area are improved, and the corrosion resistance is greatly improved.

The production scale of stainless steel pipe is expanding. The use of road transportation is a distinct market advantage of stainless steel pipe and has become one of the classic pipe materials.
