Diameter pipe materials including stainless steel diameter pipe (304304l316316l), alloy steel, carbon steel size head diameter pipe diameter pipe 20 steel q234q345 like. Diameter pipe Standard: GB American Standard British standard and non-standard high-pressure press. This product is made of carbon steel. Hebei Chiho Pipe Co., Ltd. was established in 2006, specializing in the production of carbon steel concentric reducers, reducer stainless steel, alloy steel DN25 diameter pipe diameter pipe prices, etc., which are widely used in petroleum, chemical, metallurgy , shipbuilding, paper, power, aerospace, pharmaceuticals, water treatment, chemical, construction and machinery and equipment industries, fully meet the needs of pipe connections. The company has passed ISO9001 quality system certification, and has import and export operation rights. Hebei Chiho Pipe; pipe diameter high-pressure pipe connections of different sizes, different for different industries. High pressure reducer before bonding steel-diameter pipe, use a dry cloth and lateral jack socket wiping process, when the surface of the sticky oil must wipe clean with acetone, the following points should be noted: 1. Control caliber: DIN standard (DN10-DN150), 3A / IDF standard (1 / 2'-6 '), ISO standard (Ф12.7-Ф152.4); 2, international industry standards: DIN, ISO, SMS, 3A, IDF, etc. ; 3. Material: Stainless steel 304,316,316L; 4, quality and use: the size of the inner and outer head with a high-grade polishing equipment, which will reach the surface precision requirements; this product is suitable for dairy, food, beer, beverage, pharmaceutical, cosmetics, etc. industry; 5, the external processing: according to user requirements to map, sample processing non-standard products; 6, Connection: Clamp (quick), welded, threaded (union) formula. The reduced diameter high-pressure reducers or expanding deformation pressing process, depending on the material and adjustable, to determine the use of cold or hot. Forming process commonly used to suppress necking, expanding suppress or necking plus expanding pressing DN200 steel diameter pipe manufacturers specifications on certain diameter pipe may also be stamping. Expanding process mainly to solve easily adjustable too large diameter pipe shaped by circumstances necking DN100 steel-diameter pipe, forming sometimes need to materials and products, will be expanding and necking methods combined. High Pressure reducers characteristic is the intensity was significantly higher than the same amount of carbon carbon steel, has good toughness and ductility and good weldability and corrosion resistance. Diameter carbon steel pipe manufacturers, integrity first (certified), carbon steel reducer by Chiho Hebei Industry Co., Ltd. Hebei Chiho Pipe Co., Ltd.
