Product Description

Seamless Carbon And Alloy Steel Mechanical Tubing ASTM A333 Grade 1 Carbon Steel Pipe



Carbon steel pipes are made of steel ingots or solid round steel through perforation into capillary tubes, and then made by hot rolling, cold rolling or cold drawing. Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium-pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
