  2. Tracer-gas leak testing - Wikipedia

    en.wikipedia.org/wiki/Tracer-gas_leak_testing

    As well as airbags, the air conditioning system, fuel system, and exhaust system require testing for leaks. Pacemakers and catheters have to be tested for efficacy and longevity. On planes, tracer-gas leak testing is used to quickly and safely locate fuel leaks, [3] as well as to check oxygen distribution devices and cabin pressurization systems.

  3. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    Accuracy: Some LDS are able to calculate leak flow and leak location. This must be done accurately. Robustness: The LDS should continue to operate in non-ideal circumstances. For example, in case of a transducer failure, the system should detect the failure and continue to operate (possibly with necessary compromises such as reduced sensitivity).

    In interwell tests, the tracer is injected at one well along with the carrier fluid (water in a waterflood or gas in a gasflood) and detected at a producing well after some period of time, which can be anything from days to years.

  5. Hydrostatic test - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_test

    A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection , and pressurization of the vessel to the specified ...

  6. Pressure exchanger - Wikipedia

    en.wikipedia.org/wiki/Pressure_exchanger

    By means of the application of a pressure exchange system, which is already used in other domains, a considerably higher efficiency of energy recovery of reverse osmosis systems may be achieved than with the use of reverse running pumps or turbines. The pressure exchange system is suited, above all, for bigger plants i.e. approx. ≥ 2000 m3/d ...
