Hebei Bohai Tube Co., Ltd. specializes in producing carbon steel elbow 20. Buy 20 carbon steel elbow went to Hebei Bohai Sea. The basic process of carbon steel elbow 20: According to its radius of curvature can be divided into long radius elbows and short radius elbows. It refers to the long radius elbow is equal to 1.5 times the radius of curvature of 20 # carbon steel elbow pipe diameter, namely R = 1.5D. Short radius elbow refers to its radius of curvature equal to the pipe diameter 20 # carbon steel elbow factory in Xinjiang, namely R = 1.0D. (D is the bend diameter, R is the radius of curvature) when pressing the pressure rating to points 20 # steel elbow manufacturers, about seventeen kinds, and U.S. standard pipes are the same, there are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, which is the most common STD and XS two kinds. According to the angle of bend points, 45 ° elbow, there are 90 ° and 180 ° elbow bend. Implementation of standards GB / T12459-2005, GB / T13401-2005, HG / T21635-1987, D-GD0219 and so on. Seamless carbon steel elbow elbow is very common to use a material, inexpensive, easy to use. Material is divided into: low-carbon steel, carbon steel, high carbon steel, 20 steel (20g), q235a, q235b etc., is characterized by a relatively high carbon content; divided by the standard: GB, non-standard, the international standard : German standard, Japanese standard 20 # carbon steel seamless elbow Hebei factory, American Standard, the British standard elbow. Seamless carbon steel elbow seamless steel raw materials are the main production processes for round tube → heating → perforation → three-roll rolling, rolling or extrusion → → set off pipe diameter (or reducing) → cooling → straightening → hydrostatic test (or testing) → mark → storage. schxx wall thickness grade, 90e (s) for short radius 90 degree carbon steel elbow; 90e (l), said long radius 90 degree elbow; 45e (l), said long radius 45 degree elbow; 45e (s) for short radius 45 degree elbow; 180e (s) for short radius of 180 degrees carbon steel elbow; 180e (l), said long radius bend 180 degrees; 20 # carbon steel long radius elbow plant | Cangzhou Bohai (certified) | 20 # carbon steel elbow pipe fittings provided by Cangzhou Bohai Limited.
