Stainless steel pipe is a hollow long round steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchen utensils.

Galvanized steel pipe is divided into two types: hot-dip galvanizing and electric galvanizing. Hot-dip galvanizing has a thick galvanized layer, which has the advantages of uniform coating, strong adhesion and long service life.
Read moreStraight seam pipe (ERW pipe) refers to a welded pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. The straight seam pipe is made by rolling a long steel strip of a certain specification through a high frequency welding unit and welding it with a straight seam

Read morePhosphating is a process in which chemical and electrochemical reactions form a phosphate conversion film, and the formed phosphate conversion film is referred to as a phosphating film. It can play a great role in improving the rust resistance of steel pipes (such as seamless steel pipes or welded pipes). When we are phosphating steel pipes, we should pay attention to the following five points:
