What is a flange gasket?


A flange gasket is a ring made of a material that is plastically deformed and has a certain strength. It is resistant to high temperatures, high pressure, corrosion, and has good compression and rebound rates. Most gaskets are cut from non-metal plates, or asbestos rubber sheets, asbestos sheets, PTFE sheets, and polyethylene sheets, which are produced by professional manufacturers. They can also be used for thin metal sheets (white metal, stainless steel). ) Non-metallic materials such as asbestos are wrapped into metal packaging gaskets; there are thin steel belts and asbestos tape wound gaskets, the most commonly used are stainless steel belts and graphite wound into metal spiral wound gaskets, depending on the environment, the winding tape can also be used. asbestos. Ordinary rubber gasket temperature is lower than 120 ° C; asbestos rubber gasket water vapor temperature is less than 450 ° C, oil temperature is below 350 ° C, pressure less than 5 MPa, for the general corrosive medium, the most commonly used acid-resistant asbestos board. In high pressure equipment and piping, other types of metal or gaskets made of copper, aluminum, 10 steel, stainless steel lenses are used. The contact width of the high pressure gasket and the sealing surface is very narrow (line contact), and the sealing surface and the gasket are processed with high quality. Low-voltage small-diameter wire flanges, high-pressure low-pressure large diameters are welded flanges, flange pressure and connecting bolt diameter and number are different. It is often used in other joints of petroleum, chemical, electric, metallurgical, shipbuilding, paper, pharmaceutical and plumbing, valves, pumps, manholes, pressure vessels and heat sealing equipment.
