Reducing flange technical parameters: Reducing flange execution quality standards in accordance with national standards: in strict accordance with the relevant standards formulated by the state manufacturing diameter flange specifications: DN15-DN300 diameter flange Packaging: wooden or other diameter flange Color: Metallic White Reducing Flange Feature: Anti-corrosion acid and long life, reasonable prices, smooth, acid and alkali, high temperature, reasonable prices, good appearance, texture and strong performance diameter flange production. Technology: Professional overall forging, forging manufacturing, and other processing methods: high-precision CNC lathe, lathe finishing, welding and other processing diameter flange nominal sch5s, sch10s, sch20s, sch30s, sch40s diameter flange manufacturing, etc. Standard: GB, American standard, the Russian standard, Japanese standard, such as diameter flange material: 304.316.316L.0Cr18Ni9.321.202 etc. Reducing flange Uses: Widely used in water conservancy, electricity, power plants, pipe fittings, industry, pressure vessels, etc. Reducing flange: flange nuts, bolts connection. Flange (Flange) also known as the flange or flange. Tube and pipe flanges are so interconnected parts, connected to the pipe end. Flange connection or flange joint, is defined by flanges, gaskets and bolts of the three connected to each other as a group combined seal structure removable connection pipe flange means conduit means piping flanges, used in equipment means the outlet flange on the device. There are holes on the flange, so that the two flange bolts tightly connected. Between flange sealing gasket. Flange threaded connection points (wire tapping) flange and welding flange. Flange standard system 1, DIN standard 1) common pressure rating: PN6, PN10, PN16, PN25, PN40, PN64, PN100, PN160, PN250 2) flange sealing surface:. Raised face DIN2526C face flange grooued acc DIN2512N tenon groove surface 2, ANSI standard 1) common pressure rating: CL150, CL300, CL600, CL900, CL1500 2) flange sealing surface: ANSI B 16.5 RF flanges face flange 3, JIS standard: not used 1) common pressure rating: 10K, 20K spare time, happy. . . . . . Usually when a child in the home for crop fertilizer is manure, usually side dig a hole in the ground filled with manure, after the sun a long time to catch the foot like a dried dung same. So very curious, stepped up, and the results I dragged a fecal odor of feces and embarrassed to go home, go home was also beaten. . Well I tend to me!
