Classification of seamless carbon steel pipe: seamless steel pipe is divided into hot rolled and cold rolled (DIAL) seamless steel pipe.
Hot rolled seamless 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 pipes.
Cold rolled (drawn) seamless steel pipe includes carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless steel thin-walled steel pipe, stainless thin-walled steel pipe and special-shaped steel pipe in addition to general steel pipe, low and medium pressure boiler steel pipe, high-pressure boiler steel pipe, alloy steel pipe, petroleum cracking pipe and other steel pipes.
The outer diameter of hot-rolled seamless pipe is generally greater than 32mm and the wall thickness is 2.5-75mm. The diameter of cold-rolled seamless steel pipe can be up to 6mm and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipe can be up to 5mm and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.
