Flange sealing surface of the type three: planar sealing surface for the pressure is not high, medium, and is non-toxic occasions; uneven sealing surface, suitable for occasions to pressure slightly higher; tongue and groove sealing surface for flammable, explosive, toxic, medium and high pressure situations.
Flange gaskets are placed in between the cover of the two laws Lanmi, tighten the nut, the gasket surface pressure reaches a certain value the deformation, and filled with dense cover on the surface uneven, thus making the connection does not leak tight. In the high pressure equipment and piping, the use of copper, aluminum, 10 stainless steel, stainless steel made of lens or other shaped metal gasket. High pressure gasket and sealing surface of the contact width is very narrow (line contact), sealing surface and the processing of the gasket is higher. Ordinary rubber gasket for temperature lower than 120 DEG C; asbestos rubber gasket are applicable to the water vapor temperature below 450 DEG C, the oil temperature below 350 DEG C, the pressure is 5MPa below the occasion, for general corrosive medium, the most commonly used is acid asbestos board.
Flange piece (disc) is a part of the connection between the pipe and the pipe. Connected to the pipe end, the holes are generally wear on the flange, bolts, the two flange connect. Flange gasket seal. Flanged fittings (pipe) refers to a flange (flange or connection) of the pipe fittings. It can be formed by casting and (figure not available), may also be threaded or welded together. The flange is made of a pair of flanges, a gasket and a plurality of bolts and nuts.
Flange gasket is a kind of material can produce plastic deformation, and has a certain strength of the ring. Most of the gasket is from non metal plate cutting down, or by professional plant according to the size of the provisions made, the material for asbestos rubber sheet, asbestos board, polyethylene plate; also useful thin metal plate (galvanized iron sheet, stainless steel) will be asbestos nonmetal material wrapped up made of metal gasket; and a with thin steel strip and asbestos band together winding and winding gasket.
Hebei Shengtian pipe fittings Group Co., Ltd. is the main distribution of flange, elbow, three-way, four-way, elbow, intubation, different diameter pipe, high-pressure pipe seamless steel pipe products such as distribution of manufacturers. Our products in the oil, chemical, metallurgy, machinery to enjoy a higher status, the company sincerely welcome friends from all circles at home and abroad to visit the guidance, and seek common development.
