Carbon steel elbow Material: carbon steel elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. Carbon steel elbow joint way: carbon steel elbow joint way: the way of the pipe coupling welded directly (the most common way) flanged, threaded coupling and coupling socket type and so on. Carbon steel elbow manufacturers of carbon steel elbow Category: carbon steel elbow in accordance with the production process can be divided into: welding elbow, pressing elbow, casting elbow. Hebei Chiho Pipe Supply large stamping large stamping elbow elbow first by its radius of curvature to points welded stainless steel elbow stamping plant, can be divided into long and short radius bend radius stamping stamping elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the pipe diameter, i.e. R = 1.5D. Short radius elbow refers to its radius of curvature equal to the pipe diameter welded steel stamping elbow manufacturers, namely R = 1.0D. (D is the bend diameter, R is the radius of curvature) when pressing force rating points, 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 304 180-degree elbow butt stamping plant, 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. Large stamping elbow statements: schxx wall thickness grade, 90e (s) for short radius 90 degree elbow; 90e (l), said long radius 90 degree elbow; 45e (l), said long radius 45 degree elbow; 45e ( s) that the short radius elbow 45 degrees; 180e (s) for short radius bend 180 degrees; 180e (l) indicates a long 180-degree bend radius; r (c), said concentric reducer fittings; r (e), said eccentric Reducing joint; t (s) expressed Tee; t (r), said reducing tee; cr (s) expressed Equal Stone; cr (r) represents Reducing Stone; c represents the large cap. elbow refers to all materials and manufacturing methods, all interface forms, all pressure levels elbow (or other fittings), including stamping elbow.
