Metal spiral wound gasket is a semi-metal flat gasket which is made of metal and non-metallic composite materials with spiral. With good compression rebound performance, a multi-channel seal and a certain degree of self sealing feature tight, less sensitive to the surface defects of the fang surface, on-bounding flange sealing surface, easy on, therefore, easy disassembly, It can be part of the elimination of pressure, temperature change and the effects of mechanical vibration. It can keep its excellent sealing performance under the alternating cycle of various harsh conditions such as in high temperature, low temperature, high vacuum, shock and vibration etc.
Widely used in many industries piping such as petroleum, chemical, gas, machinery, metallurgy, electric power, shipbuilding etc as well as the sealing flange junction such as valves pumps pressure vessels, condensers, towers, manholes etc.
