Product Description
Carbon steel pipes are made of steel ingots or solid round steels through perforation into capillary tubes, which are then hot-rolled, cold-rolled or cold-drawn.
Seamless steel pipes are made from a single piece of metal with no seams on the surface. According to the production method, seamless steel pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, pipe jacking, etc.
According to the cross-sectional shape, seamless steel pipes are divided into round pipes and special-shaped pipes. Special-shaped tubes have many complex shapes, such as square, oval, triangular, hexagonal, melon-shaped, star-shaped and finned tubes, etc.
Seamless steel pipes are mainly used as petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, bearings, automobiles, tractors, aviation steel pipes and high-precision structural steel pipes.
Usually made of high-quality carbon steel, such as 10, 20, 30, 35, 45, etc., such as low-alloy steel, such as 16Mn, 5MnV, etc., etc., made of hot-rolled or cold-rolled steel, such as 40Cr, 30CrMnSi, 45Mn2 , MOMnB, etc. Mainly made of low carbon steel, Buch as0 and 20 seamless pipes. The seamless machining of medium carbon steels such as 45cr and 40Cr is used to make mechanical parts such as car and tractor parts. Seamless steel pipes are generally used to ensure strength and flattening tests. Hot-rolled steel pipes are in a hot-rolled state or a heat-treated state. A combination of cold and heat for heat treatment. Low and medium pressure Boiler Seamless Steel Pipe: used to manufacture various low and medium pressure boiler booster steam pipes, water supply pipes, water wall pipes and other locomotive boiler superheated steam pipes, arch brick pipes, small pipes, etc.
