6000# forged fittings, properly called Class 6000 fittings, are forged steel fittings made to ASME B16.11 (socket weld and threaded) and used for high-pressure small-bore piping on SCH 160 and XXS pipe. The class is not a pressure in psi: it tells you which pipe wall the fitting matches, and the fitting is then rated the same as that pipe.
Raaj Fittings forges and machines Class 6000 fittings at our two plants in India in carbon, low-temperature, alloy and stainless steel, duplex and nickel alloys, and exports them across the Middle East, Europe and the Americas.
| End connection | Matching pipe |
|---|---|
| Socket weld | SCH 160 |
| Threaded | XXS |
Choose the fitting class from the pipe schedule, not from the operating pressure: a Class 6000 fitting on the matching pipe is at least as strong as the pipe itself, and the joint is rated as the pipe.
Every Class 6000 fitting is made from PMI-verified material, dimensionally inspected against the ordered standard and marked with material, size, rating and heat number. Orders are supplied with EN 10204 3.1 certificates; EN 10204 3.2 certification and inspection by the buyer's nominated third-party agency are available on request.
It is the ASME B16.11 class designation, Class 6000. It is not a pressure rating in psi; it matches the fitting to a pipe wall thickness, and the fitting is rated the same as that pipe.
Socket weld Class 6000 fittings match SCH 160 pipe. Threaded Class 6000 fittings match XXS pipe.
When the pipe is SCH 160 (socket weld) or XXS (threaded), usually because of high pressure, heavy corrosion allowance or mechanical strength requirements.
Carbon steel A105, low-temperature A350 LF2 and LF3, alloy steel F11 / F22 / F91, stainless steel F304L / F316L and others, duplex F51 / F53 / F55 and nickel alloys.
