Seamless Steel Pipe Categories: Seamless steel pipes are divided into three types: hot-rolled, cold-rolled, and cold drawn seamless pipes. Hot-rolled seamless steel pipes include general steel pipes, low and medium-pressure boiler pipes, high-pressure boiler pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes, and other steel pipes.
Cold Rolled Seamless Steel PipeIn addition to general steel pipes, low and medium pressure boiler pipes, high-pressure boiler pipes, alloy pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, we also offer carbon steel thin-walled pipes, alloy thin-walled pipes, stainless thin-walled pipes, and shaped pipes. Hot-rolled seamless pipes have an outer diameter generally greater than 32mm, wall thickness ranging from 2.5 to 75mm. Cold-rolled seamless steel pipes can have an outer diameter of up to 6mm and a wall thickness of up to 0.25mm, while thin-walled pipes can have an outer diameter of up to 5mm and a wall thickness less than 0.25mm.
