Gas testing is performed by filling a component with nitrogen and pressurising it to test its integrity. Appropriate connections are required to connect the pressure inlet of the product to the on-site instrumentation comprising pumps, regulators, accumulators, valves and pipework.
This system is then used to increase the nitrogen pressure until the desired specification is reached. Calibrated pressure transducers are used to monitor the internal pressure as it rises. The pressure is taken up and held. If the pressure drops, this indicates that there is a leakage.
