Production process of seamless steel tube precision seamless steel pipe:
DIN series tubes, cold drawn and bright annealed precision seamless steel tube is used as the tube to be galvanized. The outer wall of tube is electroplated. The caps are covered at two ends of tube to prevent it from dust.

Main Features for precision carbon steel tube:
White galvanized, color galvanized (yellow galvanized),olive green. After galvanization, the outer wall of tube has good brightness, good property for antirust and anticorrosion. 

Main Application of cold drawn precision steel tube:

This kind of tube is used in auto parts industry, in the occasion where the requirement for precision, surface finish, antirust and anticorrosion of outer wall is relatively high.

Automotive industry, Diesel engine, Engineer Machinery and other industry equipment hydraulic system, railway locomotive, aerospace, marine, and wind power equipment, heat exchanger, metal processing, etc.
