Threaded Coupling is a short piece with screw in NPT or BSP ends or one end, which is available in stainless steel, alloy steel and carbon steel. The size range is DN6-DN100. The common grade of stainless steel coupling is A182 F304/F316.
Forged threaded pipe fittings are named by its manufacturing forging process and produced according to ASME B16.11, MSS-SP-79\83\95\97 and BS3799 standards. It is a connector in between nominal bore pipes. Their material can be made of carbon steel A105 and stainless steel SS316 & 304. Threaded fittings are mainly used for small pipe diameters, generally for piping whose nominal diameter is NPS 2 or smaller. Threaded joints probably represent the oldest method of joining piping systems.
