Vacuum Box Testing & Leak Testing
Vacumm Box testing and leak testing are techniques used to inspect piping systems and tanks for weld and general system leaks. Helium and other gases are pumped into a system and the outside is inspected with a detecting devise to identify any gas excaping the system. Vacuum box testing is subjecting a system to negative pressure with a soap solution on the surface. By doing this any leaks are identified by bubbles from the leaking air showing up on the surface of the part.
