Threaded joints probably represent the oldest method of joining piping systems. Like Socket Weld fittings, threaded fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller.
Threaded piping is commonly used in low-cost, noncritical applications such as domestic water, fire protection, and industrial cooling water systems.
Threaded fittings are normally made of cast gray or malleable iron, cast brass or bronze, or forged alloy and carbon steel.
They are available in three pressure ratings: Class 2000, 3000 and 6000.
The threaded pipe fittings included elbow 90°,tee,cross,elbow 45°，full-coupling,cap(end cap),half-coupling,square head plug,hex head plug,round head plug,hex head bushing,union.
The advantages of threaded pipe fittings
Installation productivity is moderately high, and specialized installation skill requirements are not extensive.
Leakage integrity is good for low-pressure, low-temperature installations where vibration is not encountered.
