How to conduct a pressure test on pipelines in winter? Soap water freezes and cannot be detected! Thank you
What a practical and good question! ! ! Where will it be, and what will be the low temperature there? The freezing point of soapy water should be below zero degrees. If it still freezes, can some ethylene glycol be added to lower the freezing point of the soapy water? I haven’t tried this before, but you can give it a shot
Can’t we conduct the pressure test in a different season?
It’s better to use water pressure; with air pressure, the results aren’t guaranteed
