Vacuum Testing


Vacuum leak testing is the principal leak test method for testing parts that could have leakage from an external source into their housings and casings.

Parts like underwater sensors or housings, outdoor electrical housings, sealed components, and components associated with vacuum sources are all prime candidates for vacuum leak testing.

Operation of instruments that supply vacuum to test parts instead of pressure works in a similar, yet essentially opposite, manner as pressure decay testing.

Vacuum Box testing is also used to check for any leaks or fault in the welding of bottom & annular plates of the storage tank. The vacuum pump attached creates a vacuum in the vacuum box, which shows bubbles on the soap water applied on the weld in case of any leaks or faults. This is one of the most adoptive test methods to detect leak or defects and widely used in the bottom plate of tank, ships and barge bottom plates.
