Some water may remain in the Bellows convolutions after the test. If this is detrimental to the Bellows or system operation, work out the ways to remove such water.
Do not subject the Expansion Joint to test pressure higher than the specified.
Use water for pressure test free of chloride.
If the system has been designed for a gas, and to be tested with water, Check whether any provision has been made to support the dead weight.
