Purpose:

The use of large diameter stainless steel can be divided into oil well pipe (casing, tubing and drill pipe, etc.), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic support pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure fertilizer pipe, oil cracking pipe) and ship pipe. In addition, the bending and torsional strength are the same, and the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures
