  2. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks. LDS provide alarms and display other related data to the pipeline controllers to assist decision-making. Pipeline leak detection systems can also enhance productivity and system reliability thanks to reduced downtime and inspection ...

  3. 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 test ...

  4. Pigging - Wikipedia

    en.wikipedia.org/wiki/Pigging

    The blue plastic disks seal against the inside of the pipe to propel the device and to remove loose sedimentation or scale buildup. The black rectangles at the top and the circular disks in the center are magnets to attract and remove any loose metal objects in the pipe. An ultrasonic leak-detection pig.

  5. Leak - Wikipedia

    en.wikipedia.org/wiki/Leak

    Leak. A leak is a way (usually an opening) for fluid to escape a container or fluid -containing system, such as a tank or a ship's hull, through which the contents of the container can escape or outside matter can enter the container. Leaks are usually unintended and therefore undesired. The word leak usually refers to a gradual loss; a sudden ...

  6. 2022 Keystone Pipeline oil spill - Wikipedia

    588,000 U.S. gallons (14,000 barrels) The Keystone Pipeline oil spill occurred on December 7, 2022, when a leak in the Keystone Pipeline released 14,000 barrels of oil into a creek in Washington County, Kansas. [ 1] The leak is the largest in the United States since the 2013 North Dakota pipeline spill and the largest in the history of the ...

  7. Magnetic flux leakage - Wikipedia

    en.wikipedia.org/wiki/Magnetic_flux_leakage

    Magnetic flux leakage ( TFI or Transverse Field Inspection technology) is a magnetic method of nondestructive testing to detect corrosion and pitting in steel structures, for instance: pipelines and storage tanks. The basic principle is that the magnetic field "leaks" from the steel at areas where there is corrosion or missing metal.

  8. Tracer-gas leak testing - Wikipedia

    en.wikipedia.org/wiki/Tracer-gas_leak_testing

    A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks. A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.

  9. Hydraulically activated pipeline pigging - Wikipedia

    en.wikipedia.org/wiki/Hydraulically_Activated...

    Hydraulically activated pipeline pigging (HAPP) is a pigging technology applied for pipeline cleaning. The basic principle is that a pressure drop is created over a by-passable pig held back against a pipeline's fluid flow. The pipeline fluid passing through the pigs cleaning head is accelerated by this pressure drop, forming strong cleaning ...
