Hebei Chiho Pipe High Pressure Flange: for pressure higher than 10MPa piping or equipment connected to the flange. At present, including conventional high-pressure and high-pressure self-tight flange flange. Traditional High Pressure Flange: The use of the seal (oval mats, octagonal pad, lens pad, etc.) to seal the plastic deformation effect, connected to the tube end, the tube and pipe parts connected to each other, there are eyelets on the flange studs so that the two flanges tightly connected. Hebei Chiho Pipe butt neck collar with loose flange connection defined by a pair of flanges, a gasket and a number of bolts and nuts. Spacer placed between the two flange sealing surface, tighten the nut, the pressure over the gasket surface deformation reaches a certain value, and fill the sealing surface uneven, the coupling does not leak tight. Welding neck collar with loose flange screw connection points (wire tapping) flange and welding flange. Low pressure small diameter wire flange, high pressure and low pressure are the use of large diameter high pressure carbon steel flanges welded flange thickness and bolt diameter and the number of different connection flange pressures are different. According to different levels of pressure forged steel flange, flange gasket materials are also different from the low pressure asbestos gasket, high pressure asbestos gasket to metal pads are. 1. Material classified carbon steel, cast steel, alloy steel, stainless steel flanges companies, copper, aluminum, plastic, argon Ge Lek, ppc and so on. 2. production methods can be divided into forged flanges, casting flanges, welded flanges, rolled flange (large number) 3 to produce a standard can be divided into GB (Ministry of Chemical Industry, Petroleum standard, electricity standard) , American Standard, the German standard, Japanese standard, the Russian standard and so on.
