Vacuum box bubble test is one of the safest and reliable non-destructive testing methods. Vacuum Box Testing is used in order to locate seam leaks in the welds of storage tanks. A detergent solution is commonly used in this testing method and a vacuum pump is attached to the storage tank. If a leak or fault is detected, there will appear a bubble over the leak.
Vacuum Box Testing can be used on lap welds, shell to annular welds, butt welds, pressure vessels, piping systems, among many others. Vacuum Box Testing is great as it is capable of immediately locating any leaks. It can also detect the smallest leaks inside a given area.
