Overview

American standard eccentric reducer is a commonly used type of ASME standard pipe fitting. The reducer, also known as the reducer head, is one of the pipeline fittings used for connecting two different pipe diameters. According to their different shapes, they can be divided into RC concentric reducers and RE eccentric reducers.

Product Details

American standard eccentric reducers, also known as reducers, are one of the American standard pipeline fittings used in fluid pipeline construction for connecting two different pipe diameters. They can be divided into RC concentric reducers and RE eccentric reducers according to their shapes. Reducing pipe/reducer is a type of pipe fitting used for pipe diameter changes. The commonly used forming processes include reducing diameter pressing, expanding diameter pressing, or reducing diameter plus expanding diameter pressing. For some small-sized reducing pipes, stamping forming can also be used.

Reducing pipes can be divided into carbon steel (20 #, A3, Q235, Q235A, Q235B, 20G, 16Mn, Q345, Q345R, ASTM A234WPB, ASTM A105, etc.) according to their manufacturing materials; Stainless steel: (304, 304L, 316, 316L, S30408, S30403, S31608, S31603, SUS304, ASTM A403, TP321, TP317L, 347, 0Cr18Ni9, 00Cr19Ni10, 00Cr17Ni14Mo2, 1Cr18Ni9Ti, 06Cr17Ni12Mo2, 022Cr17Ni12Mo2, etc.); Alloy steel: (16MnR, Cr5Mo, 12Cr1MoV, 10CrMo910, 15CrMo, 12Cr2Mo1, A335P22, St45.8/III, A10bB, etc.); Special alloy steel: (TP310S, 904L, Incoloy800, Incoloy825, Incoloy600, Incoloy625, etc.); Dual phase stainless steel: (F51, S31803, S2205, F53, 2507, S32750, F55, 2607, S32760, etc.).

Common execution standards for large and small heads: ASME/ANSI B16.9 seamless steel pipe fittings manufactured in factories, ASME/ANSI B16.11 socket welded and threaded forged fittings, ASME/ANSI B16.28 steel butt welded small radius elbows and return bends

Application of American standard eccentric reducer head: When there is a change in the flow rate of the fluid in the pipeline, such as an increase or decrease, and the flow rate requirement does not change significantly, a reducer head is required; To prevent cavitation at the inlet of the pump, a reducing pipe is required; In order to match with the joints of instruments such as flow meters and regulating valves, reducing pipes are also required. At present, most pipeline networks require the use of reducers, mainly used in petroleum, chemical, natural gas, steam pipeline networks, hydraulic machinery, etc.
