The use of nitrogen for leak testing is common in a variety of industries. Nitrogen is best known for its use in the oil industry for testing pipelines and containment vessels, but many different industries use it for leak testing.
Pressure testing to determine whether a system is ready for full utilization is an important aspect of pre-first use testing. Parameters analyzed during pressure testing include:
- Allowable capacity of pipelines
- Identification of leaks
- Stability of fittings
- Pressure measurement
- Component integrity
