Introduction
Forged pipe fittings are essential components in heavy industry, including power generation, oil & gas, petrochemicals, and shipbuilding. Their high strength and durability make them ideal for high-pressure, high-temperature, and corrosive environments. This guide provides a practical framework for procurement engineers to source forged fittings effectively, ensuring safety, reliability, and cost-efficiency.
Key Standards to Confirm
When procuring forged pipe fittings, verify compliance with international standards:
- ASME B16.11: Forged fittings (socket-weld and threaded)
- ASTM A105 / A105N: Carbon steel for general use
- ASTM A182: Alloy and stainless steel grades (F304, F316, F11, F22, etc.)
- MSS-SP-79, SP-83, SP-95: Additional dimensional and test requirements
For specific heavy industry applications (e.g., nuclear, offshore), also check standards like ASME Section III or NACE MR0175 for sour service.
