Socket Weld Pipe Fittings

Socket Weld Pipe Fittings

A Socket Weld 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) 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. Fatigue resistance is lower than that in butt-welded construction due to the use of fillet welds and abrupt fitting geometry, but it is still better than that of most mechanical joining methods.

Socket Weld 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.
     

Advantages

  •  The pipe need not be bevelled for weld preparation.
  •  Temporary tack welding is no needed for alignment, because in principle the fitting  ensures proper alignment.
  •  The weld metal cannot penetrate into the bore of the pipe.
  •  They can be used in place of threaded fittings, so the risk of leakage is much smaller.
  •  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.
