  2. Internal erosion - Wikipedia

    en.wikipedia.org/wiki/Internal_erosion

    It is possible for water flow to cause the sides of the pipe to swell, closing it and thus limiting erosion. [7] Additionally, if the soil lacks sufficient cohesion to maintain a crack, the crack will collapse and concentrated leak erosion will not progress to a breach. [8] Cracks that allow concentrated leaks can arise due to many factors ...

    en.wikipedia.org/wiki/Echologics

    Echologics LLC is a Canadian engineering company based in Toronto that specializes in non-invasive acoustic detection of underground leaks and pipe condition assessment. [1] [2] [3] It has completed projects in North America, Europe, Australia, South Africa, and Singapore that have minimized the loss of millions of gallons of drinking water via leaking infrastructure.

    To weigh down the pipe (to ensure negative buoyancy), a 60–110-millimetre (2.44.3 in) layer of concrete surrounds the steel. [41] Each line of the pipeline was made of about 100,000 concrete-weight coated steel pipes each weighing 24 tonnes (53,000 lb) welded together and laid on the seabed.

  5. Water detector - Wikipedia

    en.wikipedia.org/wiki/Water_detector

    Most modern leak detection systems developed around the use of a water sensitive cable [1] which can be laid in long lengths and complex patterns around the base of the floor; around the perimeter of rooms; as a "barrier" over which water has to flow; following, tracing or attached directly to lines of water pipes.

  6. Tank leak detection - Wikipedia

    en.wikipedia.org/wiki/Tank_leak_detection

    European Committee for Standardization EN 13160 shows five different classes (technical methods) of leak detection systems to be used on tanks and pipes. [1] The number of the class indicates the effectiveness of the installed leak detection system. Class 1 being the highest and class 5 being the lowest level. [2] [3] [4]

  7. 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.
