ASME B16.9 Butt-Weld Fittings
ASME B16.9 is the standard for butt-weld fittings and covers various types and sizes of butt-weld fittings used for connection and reduction in piping systems. These fittings include elbows, tees, reducers, caps, etc. Overall dimensions, tolerances, ratings, testing, and marking for sizes NPS 1⁄2 to NPS 48 (DN 15 to DN 1200).
The term "wrought" means fittings made from seamless or welded pipe, tubing, plate, or forgings. Our company is a professional and reliable one-stop service manufacturers suppliers exporters. We not only provide stainless steel, nickel alloy pipes, tubes, plates, sheets, round bar, but also fabricated pipe spools service, of course, including pipe fittings, flanges, fasteners, etc.
ASME B16.9 Pipe Fitting Types
- Elbows: 45 and 90 degree long and short radius elbows, reducing elbows, long radius return, short radius elbows, short radius 180° return, 3D elbows.
- Tees: equal and reducing tees, reducing tees, reducing crosses.
- Reducers: concentric and eccentric reducers.
- Caps: caps to close the ends of pipes.
- Stub Ends: used with loose flanges.
