Socket weld fitting is a widely used pipe fitting. Do you know the advantages and disadvantages of socket weld fittings? Today we will have a discussion on the advantages and disadvantages of socket weld fittings.

Advantages of socket weld fittings

#1 The pipe needs to be beveled for preparation of weld;

#2 Temporary tack welding generally no need be required for alignment. This is because the principle in fitting would help to make sure that alignment is proper.

#3 The socket weld metal is not able to penetrate the bore of the pipe;

#4 Costs of construction have been found to be lower than butt-welded joints. Due to the elimination of special machines and the lack of exact fit-up requirements.

Disadvantages of socket weld fittings

#1 The welder should make sure that the expansion gap between the shoulder of the socket and the pipe should be 1.6mm;

#2 The internal crevices and expansion gap in socket weld systems would promote corrosion. It would be because of this reason that they have been deemed to be less suitable for radioactive or corrosive applications;

#3 These kinds of fittings would also be unacceptable for UltraHigh Hydrostatic Pressure in food industries. This is because, in addition to not allowing full penetration, it would also leave crevices and gaps that would then become very difficult to clean.
