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.

The purpose of annealing cs seamless pipe is mainly to eliminate and improve the organizational defects and internal stress left in the previous process, and to make preparations for the structure and performance of the subsequent process.

The rust removal of the cs seamless pipe is one of the key factors determining the anti-corrosion service life of the pipeline, and it is the premise of whether the anti-corrosion layer and the cs seamless pipe can be firmly combined.
