Detailed Product Description: | Seamless carbon steel elbow elbow is used as a common material, cheap, easy to use. Material: 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, American standard, British standard elbow. The raw material is carbon steel seamless steel seamless elbow, the main production processes for the round tube perforation → → heating → three-roll rolling, rolling or extrusion → detached → sizing (or reducing) → cooling → straightening → hydrostatic test (or testing) → mark → storage. schxx wall thickness grade, 90e (s) indicates short radius carbon steel elbow 90 degrees; 90e (l) represents long radius 90 degree elbow; 45e (l) represents long radius 45 degree elbow; 45e (s) indicates short radius 45 degree elbow; 180e (s) indicates short radius 180 degree steel elbow; 180e (l) represents 180 degrees long radius elbows; 1 manufacturing process can be divided into pushing, pressing, forging, casting and so on. 2 to manufacturing standards can be divided into GB, electricity standard, standard ship, chemical, water standard, American standard elbow, German standard, Japanese standard, Russia and other standard. 3 by its radius of curvature of points: can be divided into long radius elbows and short radius elbows. It refers to a long radius elbow radius of curvature equal to 1.5 times the outer diameter of the pipe, i.e., R = 1.5D; refers to its short radius elbow radius of curvature equal to the pipe diameter, i.e. R = 1.0D. Carbon steel seamless elbow in the process should pay attention to the problem of carbon steel elbow to determine the principles of heating temperature austenitizing temperature is above the material, and the inner wall of the main stress elbow to push the system when the material at this temperature is less than the yield limit. Material austenitizing temperature, the higher the heating temperature; higher material yield limit of the high temperature, the heating temperature is higher |
