Threaded & Socket Welded Steel Fittings - Pressure Classes vs. Schedules
Pressure classes, schedules and weights of pipes for threaded & socket welded fittings.
Pressure Class | 2000 | 3000 | 6000 | 9000 |
---|---|---|---|---|
Threaded Fittings | 80/XS | 160 | XXS | |
Socket-welded Fittings | 80/XS | 160 | XXS |
- Standard (STD), Extra Strong (XS) and Double Extra Strong (XXS)
- Schedule - numbers assigned to different wall thickness of pipe (i.e. schedule 80)
Threaded fittings are available in pressure classes 2000, 3000 and 6000.
