Socket weld (SW) pipe fittings have plain spigot ends, allowing for being directly inserted into a recessed area of pipes or flanges to make a tight connection. Socket welded joint construction provides benefits of zero leakage and high structural strength. Compared to butt weld fittings, socket weld fittings feature more compact design, which makes them mainly be used for small pipe diameters, generally for piping whose nominal diameter is NPS 2 or smaller.
NFF can provide you with a wide selection of SW pipe fittings in various shapes and sizes, including socket weld fitting elbows, socket weld crosses, socket weld tees, socket weld end caps, socket weld pipe couplings, socket weld pipe unions, etc. Steel bars or ingots are heated, forged and then machined by CNC lathes to make socket weld pipe fittings with precise size and high strength, enabling to satisfy your demanding piping application requirements.
