Defination:
The total number of complete cycles which can be expected from the Expansion Joint based on data tabulated from tests performed at room temperature under simulated operating conditions.
Fatigue life is dependent upon the maximum stress range to which the bellows is subjected, the maximum stress amplitude being a far less significant factor.
Influencing Factors:
Operating pressure, Operating temperature, Bellows material , the movement per convolution, the thickness of the bellows, the convolution pitch, and the depth and shape of the convolution.
EHASEFLEX ensures rigorous testing and design optimization to maximize fatigue life under varying operational conditions.
