ASTM A182 F53, UNS S32750, 1.4410 Super Duplex Stainless Steel Weld Neck RF Flange B16.5
ASTM A182 F53(UNS S32750) Weld Neck Flanges are made from a super duplex stainless steel grade that has 24% chromium, 3% molybdenum, 6% nickel and carbon, manganese, silicon, sulfur, phosphorus, nitrogen and iron in the composition. ASTM A182 F53(UNS S32750) Super Duplex Stainless Steel Flange comes under the ASTM A182 specification for high temperature and high pressure services.
ASTM A182 F53 is a super duplex stainless steel material that is commonly used for high-pressure and high-temperature applications in various industries. A weld neck RF (raised face) flange is a type of flange that has a neck that is welded to the pipe, providing a strong and leak-proof connection. This type of flange is commonly used in critical applications where leakage is not acceptable. The ASTM A182 F53 weld neck RF flange is specifically designed to meet the requirements of this high-performance material and provide a reliable connection for demanding applications. It is important to ensure that the flange is properly installed and welded by qualified personnel to prevent any leaks or failures.
Super Duplex Stainless Steel Weld Neck Raised Face Flange is a type of flange made from a high-quality duplex stainless steel material that offers superior corrosion resistance and strength. The weld neck design provides a strong connection between pipes or fittings, reducing the risk of leaks or failures. The raised face (RF) design ensures a tight seal between the flange and the mating surface, preventing fluid or gas leakage. This type of flange is commonly used in high-pressure and high-temperature applications in industries such as oil and gas, chemical processing, and offshore drilling. It is designed to withstand harsh environmental conditions and provide long-lasting performance.
