Carbon steel pipes are divided into two categories: 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 (dialed) carbon steel pipes, in addition to 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, also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes, and special-shaped steel pipes. Hot rolled seamless pipes generally have an outer diameter greater than 32mm and a wall thickness of 2.5-75mm. 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. Cold rolling has higher dimensional accuracy than hot rolling.
General carbon steel pipe: It is made of high-quality carbon bonded steel such as 16Mn, 5MnV, or 40Cr, 30CrMnSi, 45Mn2, and 40MnB by hot rolling or cold rolling. 10. Seamless pipes made of grade 20 low-carbon steel are mainly used for fluid transportation pipelines. Seamless pipes made of medium carbon steel such as 45 and 40Cr are used to manufacture mechanical parts, such as load-bearing parts for automobiles and tractors. Generally, carbon steel pipes need to ensure strength and flattening tests. Hot rolled steel pipes are delivered in either hot-rolled or heat-treated condition; Cold rolled and delivered in heat treated condition.
