High pressure flange refers to its working pressure is much higher than the general flange.So it thicker flange thickness, bolt hole and aperture than the average number of flange.Transportation to withstand higher pressure.High pressure flange are generally butt welding flange, also called the high neck flange.Larger rigidity, suitable for the occasion of high pressure and temperature.


High pressure flange sealing surface generally choose two kinds: 1. The concave and convex sealing surface, suitable for pressure slightly higher occasion;2. Grooved seal face, applicable to flammable, explosive, toxic medium and high pressure.Seal face flange gasket between the two.


Gasket is a kind of can produce plastic deformation, and has certain strength rings made of materials.Most gaskets from non-metallic plate cutting down, or produced by professional factory in accordance with the provisions, the size, the material of 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 package cushion;Another with steelskin belt with asbestos tape winding of spiral wound gasket.High pressure flange gasket used above, is to use 10 copper, aluminum, steel, stainless steel type lens or other shaped metal gasket.High pressure washer and sealing surface contact width is very narrow (line contact), processing with gasket sealing surface roughness is higher, this design has a seal.
