Gasket is a kind of ring which can produce plastic deformation and has a certain strength. Most of the gaskets are cut down from non-metallic plates, or made by professional factories in accordance with the specified size, the material is asbestos rubber sheet, asbestos board, ptfe board, polyethylene board, etc. Also useful thin metal plate (iron sheet, stainless steel) asbestos and other non-metallic materials wrapped up made of metal gasket; There is also a kind of winding gasket made of thin steel belt and asbestos belt. The most commonly used is the metal winding gasket made of stainless steel belt and graphite. According to the different use environment, the winding belt can also use asbestos. Ordinary rubber gasket is suitable for the occasion of temperature below 120℃; Asbestos rubber gasket is suitable for water vapor temperature is less than 450℃, oil temperature is less than 350℃, pressure is less than 5MPa occasions, for the general corrosive medium, the most commonly used is acid resistant asbestos plate. In high pressure equipment and pipelines, the use of copper, aluminum, no. 10 steel, stainless steel made of lens type or other shape of metal gaskets. The contact width of high-pressure gasket and sealing surface is very narrow (linear contact), and the processing finish of sealing surface and gasket is high.
Low pressure small diameter threaded flange, high pressure and low pressure large diameter are welded flange, flange thickness and connecting bolt diameter and number of different pressure is different.
