 Expansion Joint Product Testing: Hydro
Testing
Objective: The objective of this
test is 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.
|
|
After Completion: If a leak is
present, the welds will be repaired after releasing the hydro
test pressure. |
