Hebei Chiho-diameter pipe stainless steel pipe industry Specifications: 3/4 'X1 / 2' --- 48 'X 40' [DN 20 X 15 - 1200 X 1000]. Wall thickness:. Sch 5s --160 stainless steel eccentric reducer according to the national standard, American Standard (ANIS), Japanese Standard (JIS), British standard (BS), German standard (DIN), Italy superscript (UNI) and other standards . Material: carbon steel reducer 304, stainless steel, alloy steel. 11 Hebei Chiho Pipe size of the first generation produced in connection with the use of the pipeline in a good performance and operational contribution, in strict accordance with the standard form of certain ball use, divided into different categories and types in a specific use, full of important operating contribution. The size of the head (ie diameter pipe), one case of pipe fittings for pipe diameters of two different pipe valve connection; divided into concentric eccentric head size and the size of the first two. Head size is adjustable for a tube at the pipeline. Forming process commonly used to suppress necking, expanding suppress or necking plus expanding suppress certain specifications reducer valve can also be used stamping. The reduced size of the first valve diameter forming process is the size of the head with a diameter equal to the big end of the tube into the forming die, along the axial direction of the tube pressing the metal along the cavity forming motion and contraction. Reducing the size according to the size of the head diameter pipe, into one or more press-forming press forming. After the plane door width measuring four basic standard size ± 0.2mm, wood moisture 8-10%, based on the production process, measures moisture less than valve position and south humidity, door widths occur than the standard size + 0.5 ~ + 1.0mm. Hebei Chiho tube industry; concentric reducer (concentric size head) at both ends of the center line should coincide, their eccentricity tolerance of ± 5mm. Concentric reducer should not have the appearance of cracks, heavy leather wall thickness greater than the thickness of the large diameter end of the tube segment. Concentric reducer size tolerances should be specified. Reducing the size of the head tube, also known as punching diameter pipe used to connect pipes of different sizes; generally it is divided into concentric reducer and eccentric reducer two, two-port when the projector stand up after Reducer concentric when it is called concentric reducer (concentric size head), and eccentric reducer projection is cut in small round cylindrical inner eccentric reducers, reducer, Hebei Chiho (view) from Hebei Chiho Industry Limited.
