Precision seamless steel pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipe, no leakage under high pressure, high precision, high finish,

A straight seam steel pipe is a steel pipe with a weld parallel to the longitudinal direction of the steel pipe. It is usually divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe, etc. The production process of straight

Spiral seam submerged arc welded steel pipe is formed by bending hot-rolled strip steel into a spiral shape, and the inner and outer seams are welded by submerged arc automatic welding to form a spiral seam steel pipe (also called spiral welded pipe, spiral

Seamless steel pipe is an important industrial material and is widely used in petroleum, natural gas, chemical industry, electric power, shipbuilding, bridge building, military industry and other fields. Its unique properties and diverse uses make it an indispensable part of modern engineering. standard The production
