Fatigue Testing to Calculate a Life Span of 30,000 Cycles
The video shows an expansion joint bellows being cycle tested through a specified design movement of 1-1/4″ to verify the calculated life span of 30,000 cycles. The number of completed cycles is recorded throughout the duration of the test. U.S. Bellows routinely performs this test to confirm designs and ensure a high quality product. We do extensive expansion joint product testing such as x-ray, burst, hydrostatic, ultrasonic, radiography, fatigue, PMI, pneumatic, magnet particle and helium leak testing depending on customer specifications. Each bellows and expansion joint unit goes through in-process quality control using a system of travelers, and a final in-house dimensional inspection is performed prior to shipping.
