Gb5310-2008 standard seamless steel tubes are divided into two categories: hot rolled and cold rolled (dialed) seamless steel tubes.
Hot-rolled seamless steel tubes are divided into general steel tubes, low and medium pressure boiler steel tubes, high pressure boiler steel tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological steel tubes and other steel tubes.Gb5310-2008 seamless steel tube is one of the key sales products of tianjin baiyitong steel co., LTD., the main material has 20G 15CrMog 12Cr1MovG seamless steel tube and so on!
Seamless steel pipe in addition to the general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, other steel pipe, but also including carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless steel pipe, stainless steel pipe, non-rust thin-walled steel pipe, special-shaped steel pipe.The outer diameter of hot-rolled seamless tube is generally greater than 32mm, the wall thickness is 2.5-75mm, the diameter of cold-rolled seamless tube can be up to 6mm, the wall thickness can be up to 0.25mm, the outer diameter of thin-walled tube can be up to 5mm, the wall thickness is less than 0.25mm, the dimension precision of cold-rolled than hot-rolled is high.
