A53 Gr. A & A53 Gr. B Seamless Carbon Steel Pipe Fluid Tansmission
Carbon steel pipes are made by perforating steel ingots or solid round steel to form capillaries, and then hot rolling, cold rolling or cold drawing. Carbon steel has a carbon content of less than 2.11%, and its hardness is much higher than stainless steel, but it is heavier and less malleable, and it is usually "too hard and easy to fold" and rust easily. The raw material of carbon steel pipe is round tube billet. The round tube blank is cut by a cutting machine to form a blank about 1 meter in length, and then the blank is sent to the furnace and heated by the conveyor belt. The billet is fed into the furnace and heated at a temperature of approximately 1200 degrees Celsius. 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, medium and low 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.

Generally, carbon steel pipes are made of 10, 20, 30, 35, 45 and other high-quality carbon steels such as 16Mn, 5MnV and other low-alloy structural steels or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steels by hot rolling or cold rolling. Seamless pipes made of low carbon steel such as 10 and 20 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 stressed parts of automobiles and tractors. Carbon steel pipes are generally used to ensure strength and flattening tests.
