Problems with circulating water, demineralized water, and process water pipelines
Thread Content
The pipelines for circulating water, desalinated water, and process water have been backfilled. What inspections and treatments should be carried out before conducting a comprehensive pressure test? Thank you
It has already been backfilled, so it’s very difficult to deal with it; if a leak occurs, it will be a problem.
Testing for leaks on the pressure side should be done before backfilling; it is indeed rather troublesome to carry out this test after backfilling has been completed.
Thank you all for your participation. Things have reached this point – what can be done to remedy the situation? What preparations and checks are needed? I hope for some guidance
Reply to 4#: In the rain, I think we can only proceed with pressure testing; once leaks are found, then corrective actions can be taken. Water is the best choice for pressure testing, as it makes it easier to detect leaks.
