Product specification

Specification: outer diameter of hot-rolled pipe is 32~630mm. The wall thickness is 2.5~75mm. The outer diameter of cold rolled (cold drawn) pipe is 5~200mm. The wall thickness is 2.5~12mm.
Appearance quality: the internal and external surfaces of steel pipes shall be free of cracks, folds, folds, delamination, hairlines and scabs. These defects shall be completely removed, and the wall thickness and outer diameter shall not exceed the negative deviation after removal.
Both ends of the steel pipe shall be cut at right angles and the burrs shall be removed. Gas cutting and hot saw cutting are allowed for steel pipes with wall thickness greater than 20mm. The head may not be cut after the agreement between the supplier and the supplier.

product application

Seamless pipes are widely used. Seamless pipes for general purposes are rolled by ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for conveying fluid.
Supply is divided into three types according to different purposes: a. Supply according to chemical composition and mechanical properties; B. Supply according to mechanical properties; C. Supply according to hydraulic test. The steel pipes supplied according to category a and b shall also be subjected to hydraulic test if they are used to bear liquid pressure.
There are many kinds of seamless pipes for special purposes, such as boiler seamless pipes, geological seamless pipes and petroleum seamless pipes.
