Gross Leak Test (GLT)
A gross leak test procedure is performed to verify the integrity of the channels through which it flows. This analytic process is conducted on pipelines, storage vessels, and any other conduit through which an industrial product is conveyed. Leak detection using nitrogen can be done either before the first operational use of equipment or at intervals once during routine operation.
Leak testing allows industrial equipment operators to safely convey their products while minimizing the personnel’s risk of exposure to hazardous chemicals being conveyed through the production channels. Examples include testing for leaks in pipelines, and refrigeration systems, checking seals in food processing facilities, and ensuring the functionality of newly-installed fire sprinkler systems.
