What’s advantages of socket weld 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 butt weld pipe fittings, socket weld pipe fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 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.

Advantages of socket weld fittings:

Pipes need not be beveled for weld preparation.

Temporary tack welding no need for 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.

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.Email:sales@haihaogroup.com
