For cs seamless pipes, the three elements of solution treatment are temperature, holding time and cooling rate. The solution temperature is mainly determined according to the chemical composition.

The straightening process of the cold drawn seamless tubing determines the geometry of the cold drawn seamless tubing and also affects its mechanical properties.

Whether the quality of black steel seamless pipe is defective is an important criterion for uating whether the quality of the product meets the standard.

Understanding the defects of cs seamless pipes and knowing how to avoid them can reduce a lot of unnecessary losses, thereby promoting the rational use of resources.

The galvanizing of seamless pipes is divided into cold galvanizing and hot galvanizing, and the steel pipes we commonly use now are basically hot galvanized steel pipes, and cold galvanized steel pipes are no longer advocated.

Cs seamless pipes generally use three hardness indicators of Brinell, Rockwell and Vickers to measure their hardness.
