Stainless steel flanges are pipe connectors made from stainless steel materials, primarily used in construction, power, plumbing, and industrial sectors, featuring corrosion resistance and high-temperature resistance.
Material and Characteristics
Common materials include 304 (containing 19% chromium, 8.25-10.5% nickel), 316 (containing 16-18% chromium, 10-14% nickel, 2.5% molybdenum), etc., with carbon content ≤0.08%. 316 stainless steel flanges, due to their molybdenum content, offer superior corrosion resistance and high-temperature strength, making them suitable for harsh working conditions; 304L (containing 8.25-10.5% nickel) focuses more on corrosion resistance and formability.
Widely used in chemical equipment, food processing, petroleum pipelines, pharmaceuticals, and energy sectors, they can withstand high-pressure and high-temperature environments, ensuring pipeline sealing.
