What Are Pipe Fittings?
Per ASME B16.9 and ASME B16.11, pipe fittings are pre-manufactured components that connect, redirect, reduce, or terminate pipe runs in industrial and infrastructure piping systems. At RP Sales, we supply both buttweld fittings (ASME B16.9) for larger-diameter process piping and forged fittings (ASME B16.11) for smaller branch connections and instrumentation lines. Our inventory covers carbon steel (ASTM A234 WPB), stainless steel, and alloy steel grades to match every pipe specification in your project BOQ.
- Buttweld fittings: 45°/90°/180° elbows, equal/reducing tees, concentric/eccentric reducers, end caps
- Forged fittings: socket weld & threaded elbows, tees, unions, couplings, plugs, bushings
- Sizes: 1/2" to 48" (buttweld), 1/8" to 4" (forged)
- Schedules: Matching pipe schedules — Sch 40, 80, 160, XXS
