There is no difference between carbon steel pipes and black steel pipes. Black steel pipes are a common name for carbon steel pipes.
Carbon steel pipes are made of steel ingots or solid round steel perforated into capillary tubes, which are then hot rolled, cold rolled or cold drawn. Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. 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. In addition to general steel pipes, low- and medium-pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (rolled) carbon steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, and stainless steel pipes. Rusty thin-walled steel pipes, special-shaped steel pipes.
