Pressure testing is a critical aspect of pipeline testing before first use as it determines readiness for full operational use. Various mechanical and automated methods can then be used to identify defects within the industrial components being analyzed. The process typically requires channeling a steady stream of gaseous nitrogen through the selected pipes, vessels, or vats under increasing amounts of pressure.

How to Conduct a Nitrogen Leak TestĪ nitrogen leak test follows an orderly set of steps which varies depending on the nature of the equipment to be checked. These reasons make leak testing with nitrogen a superior option to other methods like hydrostatic pressure testing. Gaseous nitrogen also prevents oxidative/corrosive reactions by eliminating water vapor and oxygen from within sensitive equipment. It is an inert gas, which is hardly reactive under normal industrial conditions. Nitrogen gas possesses numerous physical qualities that make it uniquely suited to leak testing.
Examples include testing for leaks in pipelines, refrigeration systems, checking seals in food processing facilities, and ensuring the functionality of newly-installed fire sprinkler systems. Leak testing allows industrial equipment operators to safely convey their products while minimizing the personnel risk exposure from hazardous chemicals being conveyed through the production channels.
Leak detection using nitrogen can be done either before the first operational use of equipment or at intervals once during routine operation. This analytic process is conducted on pipelines, storage vessels, and any other conduit through which an industrial product is conveyed. What Is Leak Testing?Ī nitrogen leak test procedure is performed to verify the integrity of the channels through which it flows. These allow a limitless supply of nitrogen to be conveniently and economically produced wherever it is needed. In addition, nitrogen is ideal for testing in a variety of locations thanks to portable nitrogen generators. Nitrogen is inert, odorless, and low in moisture content, so it is free from many of the problems associated with using air or water for pressure testing. There are several advantages to using nitrogen for leak detection. While best known is its use in the petroleum industry for pressure testing pipelines and containment vessels, nitrogen is also popular for leak testing in a range of other industries. Nitrogen is utilized within numerous industries for leak testing.
