orange squares Expansion Joint Product Testing: Fatigue Testing


Objective: The objective of the fatigue testing is essentially to verify how many cycles a bellows can withstand before failing.
What we do: The bellows is placed on the "cycle-test machine" and bolted to a hydraulic plunger. Each cycle is counted as the bellows is compressed and returned to neutral.

Fatigue Testing / Cycle Testing



This video shows an expansion joint bellows being subjected to a cycle test as required by the customer. The expansion joint is compressed and expanded through its specified design movement of 1 and 1/4 inches to verify the calculated lifespan of 30,000 cycles. The number of completed cycles is recorded throughout the duration of the test.
