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, 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 operating contribution, in strict accordance with certain criteria form 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; the size of the head is divided into concentric and eccentric head in two sizes. The size of the head pipe for a pipe reducer at. Forming process commonly used to suppress necking, expanding repression or suppression of necking plus expanding national standard steel pipe diameter spot on certain specifications reducer valve can also 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 Chinese standard steel diameter pipe dn80, along the axial direction of the tube pressing the metal along the cavity movement and shrink forming. Reducing the size of the head according to the size, divided into one or more press-forming press forming. After the plane surrounded by measuring the width of the basic frame for standard size ± 0.2mm, wood moisture in 8-10%, based on the production process less moisture measure humidity and the south gate position, the door will be more than the width of a standard size + 0.5 ~ + 1.0mm.
