LINE TESTING

Inspect the entire system to ensure proper installation of anchors, guides and pipe supports in strict accordance with piping system drawings.

Remove shipping bars (painted in yellow) prior to pressure testing once the pipe line anchors, guides and pipe supports are in place.

Pressurise and test the line with Expansion Joint.

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.

Provide additional support due to the weight of water, if not there.
