Carbon steel pipes are divided into two types: 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. Cold rolled (dial) 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, and other
steel pipes, as well as carbon thin-walled steel pipes, alloy
thin-walled steel pipes, and stainless steel pipes. Rusty
thin-walled steel pipes, special-shaped steel pipes.
