How can air tightness be ensured after equipment repair and reset in very low-temperature environments?
Thread Content
The equipment maintenance is complete; the pipes have been connected. Before starting the machine, a pressure test for air tightness must be conducted. If there are leaks, how can one locate the source of the leakage? At an ambient temperature of zero degrees below zero (where soap water freezes as soon as it is sprayed on)
Friends from the north should have experience.
It can’t be that extreme, right? It freezes as soon as it’s sprayed out? Then use car glass cleaner, add laundry detergent; it already contains antifreeze.
How much pressure? Can’t a pressure gauge be installed? Then just do it as described in the instructions upstairs
What is the medium? If it is flammable, a combustible gas detector can be used; this is what the units that perform gas conversion for cars use. Indeed, soap water cannot be used in winter
Isn’t it required that the medium be above 5 degrees?
Use ethylene glycol mixed with dish soap, or propylene glycol – any solvent that does not freeze in winter will work
