Tower start-up leak test problems

2009-04-08View Original

Thread Content

When the tower is started and the valves are closed for a leak test, should the pneumatic valves for the inlet and outlet be included in the test unit, or should only the hand valves that are close to each other be closed based on the principle of proximity, and the pneumatic valves should be done separately. If included in the test unit, should the pneumatic valves shared by the front and rear towers be included and tested twice (it would be better to avoid leaks), or should plans be made to only test them once (I am worried about missing them due to human factors). Thanks in advance!
