Stainless steel flanges are mainly used for connecting pipes, fittings, or equipment, achieving sealing through bolt connections. They are widely used in industries such as chemical, petrochemical, fire protection, and drainage to ensure tight and safe pipeline connections. Stainless steel flanges have excellent corrosion resistance and oxidation resistance, and can maintain structural integrity in various corrosive environments, making them particularly suitable for fields such as chemical, fertilizer, fuel, and medical machinery manufacturing.
Stainless steel flanges are connected to two flat surfaces by bolts and sealed with gaskets. Common gasket materials include polytetrafluoroethylene, metal, and silicon. This connection method is not only practical, but also ensures a tight and secure connection. The material of stainless steel flanges is usually carbon steel, low-alloy steel, or stainless steel. Depending on the pressure and usage environment, the thickness and bolt specifications of the flange may also vary.
