Chiho Hebei Industry 304 concentric reducer size tolerances shall comply with Table 4.2.2-3 of. Reducing the size of the head tube, also known as Ankang supply steel-diameter pipe, tube connected to a different size, generally it points Two pipe concentric reducers and eccentric reducers, reducer when erected after the two-port is projected concentric circles, it is called concentric reducer, eccentric reducer and a projection is within the small circle cut in .304 manufacturing process of concentric cylindrical head of the easiest to use and the thick tube as a blank, and expand one end with an equal diameter or thickness of the tube as a rough, narrow end of the aperture can be. Whether flaring or necking, it is generally used to suppress mold. The current domestic commonly used progressively eccentric mold pressing eccentric reducer produced by this process three or more eccentric reducer, eccentric small head end will have a serious gap in the inner wall from the tumor, uneven thickness and oval phenomenon. When truncated by a truncated concentric reducer eccentric reducer instead of the resulting structure, because oblique section is not round but ellipsoidal surface will exist between the wrong end and the straight edges of the problem can not be fully engaged. If a new pressing process Ankang supply steel-diameter pipe, that is, first mold pressing of a concentric concentric reducer, then press into good concentric reducer eccentric reducer eccentric pressing mold to the desired integer Ankang supply carbon steel pipe diameter pipe, its inner and outer surface smooth, flat head, uniform thickness, roundness qualified, the use of fewer raw materials Hebei Chiho Pipe; stainless steel diameter pipe size head diameter pipe, also known as . One chemical pipe fittings, for connection of two different diameters. Head size is divided into concentric and eccentric head. Diameter pipe materials including stainless steel diameter pipe (304304l316316l), alloy steel, carbon steel size head diameter pipe Ankang supply steel reducers, reducer 20 steel q234q345 like. Diameter pipe standard GB American Standard British standard and non-standard high-pressure stamping "steel plate pipe fittings" quality provisions GB / T13401-2005 of Reducer Standard reducer should be consistent with current national standard "no welded steel seam pipe "GB / T 12459-2005 standard GD0506 ~ 0507 Ministry of National Standard (GB / T9112-2000) machinery of the standard (JB81-59, JB / T74-94) OGC standards (SH3406-96) Ministry of Chemical Industry Standard ( HG5010-58, HG20592-97).
