Closed-system test plan for circulating water system
Thread Content
Regarding this, is it also necessary to conduct a airtightness test for the newly installed circulating water system? There are basically no pressure vessels at all.
Firstly, the pressure testing of pipelines and pressure vessels is done separately; they cannot be tested for airtightness together； Secondly, the pipeline airtightness test is a common method for checking the quality of pipeline construction, and it has little to do with the type of medium flowing through it. Of course, for some valves in the circulating water system, the sealing performance doesn’t need to be extremely high; whether it’s possible to manufacture them is one thing, but whether they can actually function properly is another matter.
