Pipe fittings are piping component that helps in changing the direction of the flow such as elbows, tees; changes the size of the pipe such as reducers, reducing tees; connect different components such as couplings and stop the flows such as caps, fittings.
Types of Pipe Fittings
Buttweld (BW) fittings : whose dimensions, dimensional tolerances et cetera is defined in the ASME B16.9 standards. Light-weight corrosion resistant fittings are made to MSS SP43.
Socket Weld (SW) fittings
