Carbon steel tubes are made of ingot or solid round steel that is perforated into wool tubes and then hot rolled, cold rolled or cold drawn. Carbon steel pipes are divided into hot rolled and cold rolled (drawn) steel pipes. Hot rolled carbon steel pipe is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipe.
