Also called flange constructed or axon rim.
Make the pipe and tube connected parts. Connecting at the pipe. Flange have holes, can wear bolt, make two flanges are closely linked. The flange gasket seal in between. Flange flanged fittings pipe fittings (with flange (axon) refers to the pipe flanges or receive). It can be made into left vacant for the time being cast (FIG), also can constitute by threaded connections or welding. Flange connection (flange, by a pair of flange, has) a gasket and several bolts, nuts, composition. Shim between the two flanges, put after sealing gasket surface, tighten nut on the pressure up to a certain value than deformation, and after filling seal surface uneven place, make connecting closely not leak. Flange connection is a detachable connection. According to the connection parts can be divided into containers flange and pipe flanges. According to the structure type points, a whole flange, live set of flange and threaded flange. Common overall flange are plain welding flanges and butt weld ends flanges. Flat rigid poorer welding flanges, suitable for pressure p 4MPa circumstance; More than Butt flange and says high neck flange, rigid bigger, suitable for pressure high temperature of the occasion. Flange seal face type has 3 kinds: Flat-screen seal face, suitable for pressure is not high, medium non-toxic circumstance; The bump seal face, suitable for pressure slightly high circumstance; Tenon chamfer seal face, apply to inflammable, explosive, toxic medium and pressure higher occasion. Gasket is a kind of can produce plastic deformation, and has a certain intensity of materials ring. Most gaskets from non-metallic plate cutting down, or by professional factory size, its material for asbestos rubber sheet, asbestos board, polyethylene plate; Useful also thin metal plate (tin, stainless steel) will wrap up and etc. Nonmetal material asbestos made of metal-coated gasket; Still have a kind of use BoGang band and asbestos belt around the system a together coil type washers. Ordinary rubber gaskets apply to the temperature below 120circumstance; Asbestos rubber gaskets suitable for steam temperature below the 450, to oil temperature is below 350, the pressure below 5MPa occasions, for the average corrosive medium, the most common is acid asbestos board. In high pressure equipment and pipe, copper, aluminum, steel, stainless steel makes 10, the lens type or other shape metal gasket. High-pressure gaskets and sealing surface contact width is very narrow (line contact), seal face and gaskets processing finish higher.
Flange points threaded connections (pick) flange and welding wire flange. Low voltage small diameter have silk, high voltage and low voltage pick flange of large diameter are using welding flanges flanges, the thickness of the different pressure and connecting bolts is different diameters and quantity.
According to the different grades, pressure also have different flange pad materials from low-pressure asbestos gasket, high-pressure asbestos gasket to metal mat.
1. Materials to partition carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum, plastics, argon luo drain, PPC, etc.
2. Divided by making method can be divided into pushed system, suppress, forging system, casting and so on.
3. Divided by manufacturing standards can be divided into GB, electricity standard, water standard, American standard, DIN, Japanese standard, Russian standard etc
