Exhaust Spiral Wound Gasket is your good choice.The choice of gasket material mainly depends on the following three factors: temperature and pressure medium. 1. Metal gasket material. 1. Carbon steel: It is recommended that the maximum working temperature does not exceed 538℃, especially when the medium is oxidizing. High-quality thin carbon steel plates are also not suitable for use in equipment manufacturing inorganic acids, neutral or acid salt solutions. If carbon steel is subjected to stress, the equipment accident rate under hot water conditions is very high. Carbon steel gaskets are usually used for high-concentration acids and many alkaline solutions. The Brinell hardness is about 120. 2. 304 stainless steel 18-8 (chromium 18-20%, nickel 8-10%), it is recommended that the maximum working temperature does not exceed 760°C. In the temperature range of -196~538℃, stress corrosion and grain boundary corrosion are prone to occur. Brinell hardness 160. 3. The carbon content of 304L stainless steel does not exceed 0.03%. It is recommended that the maximum working temperature does not exceed 760°C. Corrosion resistance is similar to 304 stainless steel. The low carbon content reduces the precipitation of carbon from the crystal lattice, and the resistance to intergranular corrosion is higher than that of 304 stainless steel. Brinell hardness is about 140. 4. 316 stainless steel 18-12 (chromium 18%, nickel 12%), about 2% molybdenum is added to 304 stainless steel. When the temperature increases, its strength and corrosion resistance will increase. When the temperature increases, it has higher creep resistance than other ordinary stainless steels. It is recommended that the maximum working temperature does not exceed 760℃. Brinell hardness is about 160. 5. 316L stainless steel recommends that the continuous working temperature does not exceed 760℃~815℃. The carbon content does not exceed 316 stainless steel, which has better resistance to stress and grain boundary corrosion. Brinell hardness is about 140. 6. 20 alloy 45% iron, 24% nickel, 20% chromium and a small amount of molybdenum and copper. It is recommended that the maximum working temperature does not exceed 760℃~815℃. It is especially suitable for manufacturing equipment that is resistant to corrosion by sulfuric acid, with a Brinell hardness of about 160. 7. Aluminum aluminum (content not less than 99%).Exhaust Spiral Wound Gasket is your good choice.
