Introduction
Forged pipe fittings are critical components in high-pressure, high-temperature piping systems common in oil & gas, petrochemical, power generation, and industrial plants. Unlike cast fittings, forged fittings have a denser grain structure, fewer internal defects, and superior mechanical properties, making them the preferred choice for demanding service conditions. This guide provides procurement engineers with practical steps to specify, evaluate, and purchase forged fittings that meet project requirements.
Key Standards to Confirm
Before issuing an RFQ, ensure the required standard is clearly defined. The most common standards for forged fittings include:
- ASME B16.11 – Forged fittings, socket-welding and threaded
- ASME B16.9 – Factory-made wrought buttwelding fittings (applies to some forged fittings)
- MSS SP-79, SP-83, SP-95 – Additional specifications for socket-welding reducer inserts, etc.
- ASTM A105 / A182 – Material standards for carbon and alloy steel fittings
