Description
The HPFF2 is an externally pressurized expansion compensator that has several advantages over other in-line bellows joints. Since the pressure is on the outside of the bellows, more corrugations can be added to the design resulting in a joint capable of more movement. The design features pipe that acts as a liner and a casing that acts as a cover to protect the bellows from damage. An internal guide makes this a stable, rugged joint. All in-line bellows expansion joints develop anchor loads and require guiding. Refer to the design guide or consult Metraflex or your local representative for more information.
Highlights:
- Conforms to MIL-DTL-17813H
- Maximum Working Temperature 400°F
- Maximum Working Pressure 150 PSI
- Maximum Test Pressure 225 PSI at 70°F
- Body 304 Stainless Steel
- Bellows 2-Ply 304 Stainless Steel
- End fittings Copper Female Sweat Ends
- CAUTION: Silver brazing used in construction. Do not exceed 1000°F during installation. Avoid flux exposure to the stainless steel components of the HPFF2.
