The normal temperature of graphite spiral wound gasket is between -200 to 650 ℃. if in a vacuum or oxygen-free environment, the temperature can reach 800~900 ℃. But the long-term use temperature of graphite spiral wound gasket, also known as the continuous use temperature is 450 ℃. Compared with graphite gasket, graphite metal wound gasket is more resistant to high pressure, corrosion, and high temperature. Metal graphite spiral wound gasket adopts SUS304, SUS316 metal tape, graphite and other soft materials , through alternating, overlapping, twisted and fixed by welding at the beginning and end of the metal belt, the product is made. Thus, it has good elasticity.
