Product Name: Steel Concentric Reducer, Concentric Reducer. Model NO.: DN20x10-DN1500x1400 Connection Type: Flange Cross-Section Shape: Round Medium: Liquid Diameter: 273mm Standard: ASTM, GB, API, DIN, JIS Material: Carbon Steel MPa Classfication: Medium Pressure Piping Temperature Classification: Medium Temperature Piping Trademark: none Transport Package: Wooden Paleet Specification: DN20x10-DN1500x1400 Origin: China Product Description Reducing pipe is a kind of pipe fitting used for pipeline caliber. The commonly used forming process is reduced-diameter pressing, expanded-diameter pressing or reduced-diameter plus expanded-diameter pressing, and certain specifications of different-diameter pipes can also be formed by stamping.Reducing / expanding formingThe reducing and forming process of the large and small heads is to put the tube blank equal to the large end diameter of the small and large heads into the forming mold, and press the tube along the axial direction of the tube blank to move the metal along the mold cavity and shrink the mold. According to the size of the reducer, it can be divided into one press forming or multiple press forming.StampingIn addition to using steel pipes as raw materials to produce large and small heads, some sizes of large and small heads can also be produced by using a steel plate stamping process. The shape of the die used for stretching is designed with reference to the inner surface size of the large and small heads, and the steel plate after blanking is stamped and stretched with a die.Specification:Nominal SizeBevel Outer DiameterEnd-to-EndBig EndianLittle EndianDND/mmD1/mmH/mm20x1526.921.33820x1026.917.23825x2033.726.95125x1533.721.35132x2542.433.75132x2042.426.95132x1542.421.35140x3248.342.46440x2548.333.76440x2048.326.96440x1548.321.36450x4060.348.37650x3260.342.47650x2560.333.77650x2060.326.97665x5073.060.38965x4073.048.38965x3273.042.48965x2573.033.78980x6588.973.08980x5088.960.38980x4088.948.38980x3288.942.48990x80101.688.910290x65101.673.010290x50101.660.310290x40101.648.310290x32101.642.4102100x90114.3101.6102100x80114.388.9102100x65114.373.0102100x50114.360.3102100x40114.348.3102125x100141.3114.3127125x90141.3101.6127125x80141.388.9127125x65141.373.0127125x50141.360.3127150x125168.3141.3140150x100168.3114.3140150x90168.3101.6140150x80168.388.9140150x65168.373.0140200x150219.1168.3152200x125219.1141.3152200x100219.1114.3152200x90219.1101.6152250x200273.0219.1178250x150273.0168.3178250x125273.0141.3178250x100273.0114.3178300x250323.9273.0203300x200323.9219.1203300x150323.9168.3203300x125323.9141.3203350x300355.6323.9330350x250355.6273.0330350x200355.6219.1330350x150355.6168.3330400x350406.4355.6356400x300406.4323.9356400x250406.4273.0356400x200406.4219.1356450x400457406.4381450x350457355.6381450x300457323.9381450x250457273.0381500x450508457508500x400508406.4508500x350508355.6508500x300508323.9508550x500559508508550x450559457508550x400559406.4508550x350559355.6508600x550610559508600x500610508508600x450610457508600x400610406.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 Usage:LPG pipeline engineering, natural gas pipeline engineering, chemical plants, power plants, shipyards, pharmaceuticals, dairy products, beer, beverages, water conservancy, etc.
