A182 F53 Socket Weld Elbow , UNS S32750 Super Duplex Steel Forged Fitting
Overview
A182 F53 / UNS S32750 pipe fittings is occupation of installing or repairing piping or tubing systems that transfer liquid, gas, and occasionally solid materials. It requires preparing or selecting pipe or tubing, joining it together by various means, and the location and repair of leaks. Super Duplex pipe fittings are very highly resistant to general corrosion and to pitting and crevice corrosion in high chloride, hot environments. It is not recommended for temperatures below -50°C or above +300°C, because of reduced toughness outside this range. Super Duplex Fittings has high resistance to intergranular corrosion and very high resistance to stress corrosion cracking in both chloride and sulphide environments. It can be fabricated by the process of cutting, bevelling, and welding. If Super Duplex Stainless Steel Pipe Fittings becomes embrittledit can only be rectified by a full solution annealing treatment. It can't be hardened by thermal treatment.
What is socket weld fitting?
SW Fittings are family of high pressure fittings are used in various industrial processes.
- They are used for lines conveying flammable, toxic or expensive material where no leakage can be permitted, and for steam 300 to 600 PSI.
- They are used only in conjunction with ASME Pipe and are available in the same size range.
- They are used in areas where pipe-work is permanent and are designed to provide good flow characteristics.
- They are are produced to several ASTM standards and are manufactured in accordance with ASME B16.11. The B16.11 standard covers pressure-temperature ratings, dimensions, tolerances, marking, and material requirements for forged carbon and alloy steel. Acceptable material forms are forgings, bars, seamless pipe, and seamless tubes which conform to the fittings chemical requirements, melting practices, and mechanical property requirements of ASTM A105, A182, or A350.
- They are available in three pressure ratings.. Class 3000, 6000 and 9000.
