Expansion Joint Product Testing: Hydro-Testing
Objective: The objective of this test is to check for leakage or cracks in the welding.
What We Do: The bellows is completely filled with a liquid such as water. Pressure is slowly applied to the liquid until the required pressure is reached. This pressure is held for at least 30 minutes at which point the component is inspected visually to locate leaks.
Completion: If a leak is present, the welds will be repaired after releasing the hydro test pressure.
