Stainless Steel Bellows are extensively utilised where either temperature, pressure or media prevent the use of Rubber Bellows. As with Stainless Steel Hose assemblies, Stainless Steel Bellows are produced from thin wall tube with the number of convolutions determining the available movement.
With a Bellows unit, only a comparatively small number of convolutions can be safely engineered before the unit becomes unstable under pressure. For greater movement requirements, either additional bellows must be installed, or an alternative system design must be employed.
As specific design criteria is generally the case with each expansion problem, each Bellows is produced to customers requirements, including length, pressure, end termination and movement requirements.
