Flat welding flange standards shall apply

　　Flat welding flange of the poor rigidity, suitable for pressure p 4 mpa occasions or less; Butt welding flange is also called the high neck flange, large rigidity, suitable for the occasion of high pressure and temperature. There are three kinds of flange sealing surface model: planar seal face, is suitable for the occasion of pressure is not high, medium non-toxic; Concave-convex sealing surface, suitable for pressure slightly higher occasion; Mortise sealing surface, suitable for flammable, explosive, toxic medium and high pressure situation.

　　Flange gasket is a kind of can produce plastic deformation, and has certain strength rings made of materials. Most of the non-metallic plate flange gasket from cutting down, or by a professional factory size produced by the regulation, its material for asbestos rubber sheet, asbestos board, PE board, etc.; Also useful sheet metal (tin, stainless steel) will be made of asbestos etc. Nonmetal material wrapped metal gasket.

　　We have adopted advanced production equipment and technologies to manufacture our blind flanges and threaded flanges,which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion
