Cangzhou Bohai Pipe Fittings Co., Ltd. specializes classification 20 # carbon steel stamping elbow elbow, according to its radius of curvature to points 20 # carbon steel elbow, can be divided into long radius elbows and short radius elbows. Long bend radius refers to its radius of curvature equal to 1.5 times the pipe diameter 20 # carbon steel elbow manufacturers, namely R = 1.5D. short radius elbow refers to its radius of curvature equal to the pipe diameter, ie R = D. Where D is the diameter of the elbow, R is the radius of curvature. If the pressing force rating points, approximately seventeen kinds of produce 20 # carbon steel elbow, and the United States is the same as the standard tube. Advantages of steel stamping elbow production process mainly in the following aspects: First, steel stamping elbow for petroleum, natural gas, chemicals, utilities, construction and boiler piping system industries. Second, the need for raw materials tube, pipe saving equipment and tooling costs, and get arbitrarily large diameter and wall thickness of the relatively thin carbon steel elbow. Third, the blank plate or developable surface for wholesale 20 # carbon steel elbow, so simple cutting, easy to ensure accuracy, easy assembly and welding. Fourth, because of these two reasons, you can shorten the manufacturing cycle, the production cost is greatly reduced. Because does not require any special equipment, especially for on-site processing of large carbon steel elbow. Material from steel elbow include: carbon steel, alloy steel, stainless steel, copper, aluminum ,,,, points from the production process, including: stamping, push the system, butt, forged from the specification points ,,,, include: 90 degrees, 45 degrees, 180 degrees, 1D, 1.5D, 2D, 2.5D, 3D ,,,,, from use Category include: high pressure elbow, low elbow, elbow thick, welded elbow seamless seamless, straight seam elbow, adjustable elbow, elbow chicane across elbow, socket elbow, elbow trenches, concrete pump elbow, wear elbow, elbow insulation, corrosion bend head, sanitary elbow, ship standard 20 # carbon steel elbow, 20 # carbon steel elbow, Ltd.
