Carbon steel pipes are made from steel ingots or solid round steels through perforation into capillaries, which are then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe occupies an important position in my country's steel pipe industry

Classification

Carbon steel pipes are divided into hot-rolled and cold-rolled (drawn) steel pipes

Hot-rolled carbon steel pipes are divided into ordinary 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 (dial) carbon steel pipes are divided into ordinary steel pipes, medium and low pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, other steel pipes, as well as carbon thin-walled steel pipes, alloy thin-walled steel pipes and stainless steel pipes. Rusty thin-walled steel pipes, special-shaped steel pipes. The outer diameter of the hot-rolled seamless pipe is generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of the cold-rolled seamless pipe can reach 6mm, and the wall thickness can reach 0.25mm. The outer diameter of the thin-walled tube can reach 5mm, and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling

Ordinary carbon steel pipe: Use 10, 20, 30, 35, 45 and other high-quality carbon steel such as 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel to be hot-rolled or cold-rolled. Seamless pipes made of low carbon steel such as 10 and 20 are mainly used for fluid transportation pipelines. Seamless pipes made of 45, 40Cr and other medium carbon steels are used to manufacture mechanical parts, such as the stressed parts of automobiles and tractors. Carbon steel pipes are generally used for guaranteed strength and flattening tests. Hot-rolled steel pipes are delivered in hot-rolled or heat-treated state; cold-rolled steel pipes are delivered in heat-treated state
