A socket weld fitting is used to connect pipes in high-pressure and small-diameter piping systems by inserting the pipe into a recessed area of the fitting and then welding it in place.

Purpose & Advantages:

Strong, Leak-Proof Connection – The weld around the pipe ensures a tight seal, preventing leaks in high-pressure systems.
Smooth Flow Path – The internal bore matches the pipe, reducing turbulence and improving flow efficiency.
High-Pressure Applications – Used in systems handling steam, oil, gas, and chemicals due to its strength and durability.
Less Welding Required – Compared to butt-weld fittings, only a fillet weld is needed, making installation easier.
Better Fatigue Strength – Provides better fatigue resistance than slip-on fittings, making it suitable for vibrating or high-stress environments.

Common Uses:

Oil and gas pipelines
Chemical processing plants
Power plants
High-temperature and high-pressure fluid systems
