Size of the first major applications of carbon steel industry in Hebei Chiho Pipe; 1 steel head size suitable for chemical, petroleum, metallurgy, light industry, electricity, plumbing, food, medicines, fibers, inks and other industries of water, gas, steam The control of oil and corrosive media. 2. The sanitary valves, fluid pipe fittings, steel diameter pipe size head, special industry-specific fittings and mechanical equipment can be used for dairy products, pharmaceuticals, beer, drinks, cooking oil and other industries to meet their professional requirements. 3. According to different standards of products, it can be adapted to the corresponding equipment standards, carbon reducers wholesale, and users can request the production of non-standard products for special purposes. As the name suggests the use of carbon steel size head made of carbon steel, the main representatives have 20 #, Q235, Q345,16Mn like. It is used to connect two different pipe diameters between. According to different shape, divided into concentric and eccentric head size of the first two sizes. Concentric is well understood that the center of the circle at both ends of the tube on the same line is called concentric size head, otherwise it is eccentric head. [1] The main implementation of standardized and Industry Standards (HG / T5010-1958, HG / T20592-2009 machinery of the standard (JB / T81-1959, steel-diameter pipe manufacturer, JB / T74-1994) OGC standards ( SH3406-1996) National Standard (GB / T9112-2000) Chiho Hebei Industry; concentric reducer (concentric size head) does not produce corrosion, pitting, corrosion or wear can fully play a good role in the industry and. performance. concentric reducer (concentric size head) show in certain industries and sectors important role and performance, display certain advantages and characteristics in use, concentric reducer or metallic materials used in construction materials of the highest intensity I. concentric reducer (concentric size head) resistance of air, steam, water and other corrosive medium and weak acid, alkali, salt and other chemical etching medium corrosion of steel. Also known as acid-resistant stainless steel. practical applications, often weak corrosion medium corrosion of steel called a concentric reducer, and the chemical resistance of steel known as acid corrosion of steel. As the two differences in the chemical composition, the former is not necessarily resistant to chemical corrosion, while the latter are generally a stainless steel. concentric reducer (concentric size head) of reduced diameter forming process is equal to the diameter of the large end diameter pipe tube into the forming die, along the axial direction of the tube pressing the metal Movement along the mold cavity and a contracted form. Depending on the size reducer adjustable, divided into one or more press-forming press forming. concentric reducer forming is expanding the use of less than the diameter of the tube diameter pipe big end, Shaanxi carbon steel-diameter pipe, along with the inner tube inner diameter expanding die forming. concentric reducer (concentric size head) expanding process mainly to solve easily adjustable too large diameter pipe formed by necking the case, sometimes depending on the material and Product forming desired, expanding and necking methods used in combination. In the reduced diameter or expanding deformation pressing process, depending on the material and adjustable, to determine the use of cold or hot. In general, try to use cold , but the situation for many adjustable and cause severe hardening of the wall thickness of partial thickness of the case or alloy material should adopt hot carbon steel reducer steel reducer Shaanxi wholesale _ _ by the Hebei Chiho Chiho Hebei Industry Limited.
