Description: Externally pressurised bellows are offered by Flexican Bellows & Hoses. When large amounts of axial deflection are required in piping systems of relatively high pressure, bellows that are internally pressurised have limitations due to the phenomenon called squirm. The externally pressurised expansion joint, in which the bellows elements are arranged so that they are exposed to the media on their external surface, and are therefore externally pressurised, is an ideal unit. Externally pressurising a bellows eliminates squirm as a limitation to the design and permits the safe acceptance of large amounts of axial thermal expansion.
