Product Description
Butt Welding ReducerButt welding reducer is one of pipe fittings, which is used to connect two different diameters. According to the different shapes, it can be divided into (RC concentric diameter pipe) and (RE eccentric diameter pipe). Butt welded pipe with different diameters (big and small heads) is a kind of pipe fittings used in pipe with different diameters. Usually, the forming process is shrinkage pressing, expanding pressing or shrinkage and expanding pressing. Stamping forming can also be used for some specifications of different diameter tubes. The Material of Butt welding reducerButt welding reducer is divided into carbon steel, stainless steel, stainless steel, alloy steel, alloy steel, special alloy steel, dual-phase stainless steel according to manufacturing material; carbon steel: (20#, A3, Q235A, Q235B, 20G, 16Mn, ASTM A234WPB, ASTM A10505, etc.); stainless steel: (304, 304304L, 316L, 316L, 316L, 316L, 316L, S304080808, S30403, 31608S31608, S31603, S31603, S31603, S31603, SUS31603, SUS304S304S304S304S304, ASTM, ASTM A403, TPTM 403, TP321, TP317L 14M 1Cr18Ni9Ti, 1Cro2, 1Cr18Ni9Ti, 06Cr17Ni12Mo2, 06Cr17Ni12Mo2, 022Cr17Ni12Mo2, 022Cr17Ni12Mo2, etc.); alloy steel: (16MnR, Cr5Mo, 12Cr1MoV, 10CrMo910, 15CrMo, 12Cr2Mo1, 12Cr2Mo1, A335P22, St45.8/III, A10bB, etc.); special alloy steel: (TP310S, 904L, Incoloy800, Incoloyoyoyoy800, Incoloy825, Incoloy600, Incoy625, etc.); dual-phase stainless steel: (F51, S31803, S31803, S231803, S231805, S2805, S220F55, 2607, S32760, etc.Technology of Butt welding reducer Variable-diameter pipe (big and small head) is a kind of pipe fittings used in the variable-diameter pipe. Usually, the forming process is shrinkage pressing, expanding pressing or shrinkage and expanding pressing. Stamping forming can also be used for some specifications of different diameter tubes.(1) Reduction/Expansion FormingThe shrinkage forming process of different diameter tube is to put the tube blank with the same diameter as the big end of the tube into the forming die, and by pressing along the axial direction of the tube blank, the metal moves along the die cavity and shrinks to form. According to the size of diameter change of different diameter pipe, it can be divided into one pressing forming or multiple pressing forming. Diameter enlargement is formed by using a blank smaller than the diameter of the large end of the pipe with an internal punching die along the inner diameter of the tube blank. The expanding process mainly solves the problem that it is not easy for the large diameter pipe to be formed by shrinking. Sometimes, according to the need of material and product forming, the methods of expanding and shrinking are combined. In the process of reducing or expanding deformation and pressing, cold or hot pressing is adopted according to different materials and changing sizes. Usually, cold pressing should be used as far as possible, but hot pressing should be used for severe work hardening caused by multiple diameter changes, thick wall or alloy steel materials.(2) StampingIn addition to using steel pipe as raw material to produce different-diameter pipe, some specifications of different-diameter pipe can also be produced by stamping process of steel plate. The die used for drawing is designed according to the dimension of inner surface of different diameter pipe, and the steel plate after cutting is stamped and stretched by the die.(3) Application of different diameter pipe (big and small head)1. When the flow rate of the fluid in the pipeline changes, such as increasing or decreasing, and the flow rate requirement does not change much, it is necessary to use different diameter pipe.2. In order to prevent cavitation at the inlet of the pump, it is necessary to use different diameter pipe.3. In order to cooperate with instruments such as flowmeters and control valves, different diameter pipes are also needed.BUTT-WELDING PIPE FITTINGS DETAILS
