Marine flange gasket
Marine flange gasket is a kind of ring made of material which can produce plastic deformation and has certain strength. Most gaskets are cut from non-metallic sheets, or are manufactured by specialized factories according to specifications: size, the materials are asbestos rubber sheets, asbestos sheets, tetrafluoro sheets, polyethylene sheets and so on; and metal-clad gaskets are made by wrapping asbestos and other non-metallic materials with thin metal sheets (white iron sheets, stainless steel). There is also a kind of winding gasket made of thin steel strip and asbestos strip. The most commonly used flange gasket is the metal winding gasket made of stainless steel strip and graphite. According to the use environment, the winding strip can also be made of asbestos.
Metallic gaskets
Ordinary rubber gaskets are suitable for situations with temperature lower than 120 C; asbestos rubber gaskets are suitable for situations with steam temperature lower than 450 C, oil temperature lower than 350 C and pressure lower than 5 MPa. For general corrosive media, acid-resistant asbestos board is the most commonly used. In high-pressure equipment and pipelines, lenticular or other shaped metal gaskets made of copper, aluminium, steel No. 10 and stainless steel are used. The contact width between the high pressure gasket and the sealing surface is very narrow (line contact), and the processing smoothness between the sealing surface and the gasket is relatively high.
