What do you mean by flange?
Most ring gasket is from non metal plate cutting down, or by professional plant size, the material for asbestos rubber Board, asbestos board, polyethylene plate; also useful thin metal plate (Bai Tiepi, stainless steel) asbestos nonmetal materials such as wrapping made of metal gasket; and a belt winding and asbestos tape with thin steel and the spiral wound gasket. The ordinary rubber gasket for temperature below 120 DEG C applications; asbestos rubber gasket is suitable for steam temperature lower than 450 DEG C, the oil temperature is below 350 DEG C, the pressure is lower than the 5MPa of the occasion, for general corrosive medium, is the most commonly used acid asbestos board. In high pressure equipment and piping, metal gasket with lens type copper, aluminum, stainless steel, No. 10 made of or other shapes. High pressure gasket and sealing surface of the contact width is very narrow (line contact), finish machining and gasket sealing surface of high degree.
According to the connected components can be divided into container flange and pipe flange. According to structure type, integral flange, loose flange and threaded flange. Integral flange are common flange and butt welding flange. Less rigid flange, suitable for pressure P is less than or equal to 4MPa occasion; also called high neck flange flange, rigidity, suitable for high pressure and high temperature conditions. The flange sealing surface of the three types: planar sealing surface for the pressure is not high, medium non-toxic occasions; uneven sealing surface, suitable for higher pressure situations; the sealing surface of the tenon, for Yu Yiran, explosive, toxic medium and high pressure the occasion. Gasket is a can produce made of plastic deformation, and has a certain strength of the material.
1. flange flange connection flange (flange) connection is an important connection pipeline construction. Flange connection is the two pipes, fittings or equipment, each first fixed on a flange on the flange between the two, and flange pad, fastened together with bolts, completed some fittings and connected. Equipment have built flange, flange connection also belongs. Sub threaded flange connection (wire) flange and welding flange. Low voltage and small diameter wire flange, high pressure and low pressure are the use of large diameter welded flange, different pressure flange thickness and bolt diameter and the number is different according to different levels of pressure. The flange pad also has a variety of materials, from the low pressure and high pressure asbestos asbestos pad pad to the metal pads are flanged. Easy to use, able to withstand greater pressure. In the industrial pipeline, flange connection is very wide Pan. Within the family, the small diameter of the pipe and low pressure, see flange connection. If a boiler room or a production site, everywhere is the flange connection of pipes and equipment. Also called flange or flange. The pipe and pipe interconnected parts. The holes are connected to the pipe end. Flange wear, bolt, so that the two flange abuts. The flange gasket seal. Flanged fittings (flanged pipe fittings) with a flange (flanged or disk) pipe. It can be cast into a (figure not available), may also be threaded or welded flange connection (flange,. Joint) composed of a pair of flanges, a gasket and a plurality of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, so that does not leak tight connection. The flange connection is a removable contact Answer.
