A182 F53 Socket Weld Elbow , UNS S32750 Super Duplex Steel Forged
Fitting
Overview
A182 F53 / SAF 2507 / 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.
