  2. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.

    The world's largest natural oil seepage is Coal Oil Point in the Santa Barbara Channel, California. [33] Three of the better known tar seep locations in California are McKittrick Tar Pits, [34] Carpinteria Tar Pits and the La Brea Tar Pits. [35] At Kern River Oil Field, there are no currently active seeps. However, oil-stained formations in the ...

  5. Hydrostatic test - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_test

    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 test pressure. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss.

  6. Leak-down tester - Wikipedia

    en.wikipedia.org/wiki/Leak-down_tester

    A compression tester. Leak-down testing is a static test. Leak-down tests cylinder leakage paths. Leak-down primarily tests pistons and rings, seated valve sealing, and the head gasket. Leak-down will not show valve timing and movement problems, or piston movement related sealing problems. Any test should include both compression and leak-down.
