API 5L ASME A53 GR B Carbon Steel Seamless Pipe Tube for Application of Boiler Superheater
Product Picture
Product Details
Seamless carbon steel pipe is made of steel ingot or solid tube blank, which is perforated into a blank, and then hot-rolled, cold-rolled or cold drawn. Seamless carbon steel pipe plays an important role in China's steel pipe industry.
Specification of seamless steel pipe is indicated by outer diameter * wall thickness in mm.
Classification of seamless carbon steel pipe: seamless steel pipe can be divided into hot rolling and cold rolling (drawing) 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, oil cracking pipe, geological steel pipe and other steel pipes.
Cold rolled (drawn) seamless steel pipe includes general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe and other steel pipes, as well as carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless thin-walled steel pipe and special-shaped steel pipe. The outer diameter of the hot-rolled seamless pipe is generally greater than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe.
