What Are SS 347 Tube Fittings?
SS 347 Tube Fittings connect tubes and pipes in industrial systems. Manufacturers make these fittings from Super Duplex Stainless Steel grade 347, identified as UNS S34750 or ASTM A182 F53. The material combines the properties of austenitic and ferritic stainless steel, providing superior strength and excellent corrosion resistance.
Super Duplex 347 Tube Fittings serve demanding industrial applications where standard stainless steel may fail due to aggressive chemicals, seawater exposure, or high-pressure conditions. These fittings create secure and leak-proof connections in piping systems used for fluid transfer, gas handling, and instrumentation control.
SS 347 Tube Fittings are available in different configurations such as compression fittings, ferrule fittings, elbows, tees, unions, connectors, reducers, and adapters. Their robust design allows them to operate efficiently in extreme temperatures and corrosive environments.
Industries in Turkey prefer SS 347 Tube Fittings because of their low maintenance requirements, long service life, and excellent mechanical properties. Offshore drilling platforms, petrochemical plants, marine installations, desalination systems, and chemical processing facilities use these fittings.
