• A Socket Weld Fitting is a pipe attachment detail in which a pipe is inserted into a recessed area of a valve,fitting or flange.
• In contrast to buttweld fittings, socket weld fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 4 or smaller.
• To join pipe to valves and fittings or to other sections of pipe, fillet-type seal welds be used. Socket-welded Joints construction is a good choice wherever the benefits of high leakage integrity and great structural strength are important design considerations.

Details Of Socket Weld Fittings:

• 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 fittings. Acceptable material forms are forgings, bars, seamless pipe, and seamless tubes which conform to the fittings chemical compositions, melting practices, and mechanical property requirements of ASTM A105, A182, or A350.

Advantages:

• The pipe need not be beveled for weld preparation. Temporary tack welding is not needed for alignment, because in principle the fitting ensures proper alignment.
• The weld metal can not penetrate into the bore of the pipe.They can be used in place of threaded fittings, so the risk of leakage is much smaller.
• 3. Radiography is not practical on the fillet weld; therefore correct fitting and welding is crucial. 
• The fillet weld may be inspected by surface examination, magnetic particle (MP), or liquid penetrant (PT) examination methods. Construction costs are lower than with butt-welded joints due to the lack of exacting fit-up requirements and elimination of special machining for butt weld end preparation.

• The welder should ensure for a expansion gap of 1/16 inch (1.6 mm) between de pipe and the shoulder of the socket. 
• The expansion gap and internal crevices left in socket-welded systems promotes corrosion and make them less suitable for corrosive or radioactive applications where solids buildup at the joints may cause operating or maintenance problems. 
• Generally require butt welds in all pipe sizes with complete weld penetration to the inside of the piping.
• Socket welding are unacceptable for UltraHigh Hydrostatic Pressure (UHP) in Food Industry application since they do not permit full penetration and leave overlaps and crevices that are very difficult to clean, creating virtual leaks.
• The purpose for the bottoming clearance in a socket weld is usually to reduce the residual stress at the root of the weld that could occur during solidification of the weld metal, and to allow for differential expansion of the mating elements.
