Leakage tests using air
Leakage tests using air
(OP)
Hi all,
Has anyone performed leakage tests with air on hydraulic/fuel/water system after installation? Our contractor insists that a small amount of air leakage occurs in pumps/valves/closures, and a threshold is necessary to define the amount of leakage to say that test is failed. But we've always performed leakage tests with water and there was no threshold: any leakage was a failure. I assume that the leakage from equipment is an equipment design property, but can an air leakage happen from pipe connections, couplings etc?
