The HPQFF3 has all the features and advantages of the standardHPFF3compensator with the addition of nickel-plated guides for quiet operation. This is the ideal compensator to use near occupied spaces.The HPQFF3 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. Quiet comps are ideally paired withPGQquiet guides.All in-line bellows expansion joints develop anchor loads and require guiding. Additionally, the HPQFF3 is often installed in risers. Risers develop additional loads compared to horizontal pipe runs. For riser applications refer toUnderstanding The Dynamic Of Riser Design In Skyscrapers, or consult Metraflex or your local representative for more information.
