  • Air Leak Test for Low Pressure Pipelines

    A guide on how-to-implement the Air Leak Test at gravity pipelines by following the right rules and regulations as per EN 1610. Air Leak Test is one of the test methods for testing any leakage at the gravity pipelines. The other method is testing with water. For the details of the water test, you may refer to our previous articles depending on the methods “

  • Direct and Indirect Permeability of Fissured Tills

    Comparison of direct and indirect measurements of water permeability on relatively large undisturbed and compacted Scottish till specimens in rigid-wall (Rowe cells) and flexible-wall (triaxial cells) permeameters shows the interaction of macro-fabric, test method, evaluation basis, effective stress, and possibly sidewall leakage. At low stresses, the sidewall leakage in a Rowe cell is the most ...

  • The Hall Element Method for Current Sensing

    A few months back, we posted a blog discussing the 6 different current sensing methods used in the current meters and sensors developed by Hioki.  Here, we’re highlighting the sensors that incorporate a Hall Element to detect current. A Hall Element is a semiconductor sensor that applies the Hall Effect principle to measure the flow of current through a conductor via the magnetic ...

  • Hydrostatic Pressure Test

    A hydrostatic test is performed to determine the integrity and soundness of pressure vessels and piping joints. A decrease in the applied pressure or leakage through the products or joints or plastic deformation or distortion or bulging in the product is indication of inadequate quality of the product under test.   This test method is also termed as Leak testing ...

  • High throughput leak detection

    How can you improve leak testing precision and throughput? Various methods have historically been used to check leaks in systems and components—from bubble tests to rotameters and pressure loss detection. While these traditional methods have their place, they each have serious drawbacks in accuracy, throughput, and automation. You may be faced with more demanding ...

  • Case study - Hetch Hetchy Water and Power Project (SFPUC)

    Service: Magnetic Flux Leakage (MFL) Client: San Francisco Public Utilities Commission (SFPUC) Project Date: 2007 to 2010 Location: California, USA Type of Pipeline: Water Transmission Main Diameter: 56-inch to 72-inch Pipe Material: Steel San Francisco Public Utilities Commission (SFPUC) operates three parallel cement mortar-lined steel pipelines 47.5 miles long, ...

  • Quantification of leakage in batch biogas assays

    Avoiding leaks is essential for accurate measurement of biogas production by batch assays. Here we present a simple method for detecting leaks and correcting results, based on the change in bottle mass during incubation. Three experiments were carried out using pure chemicals, wastewater sludge, and other complex substrates to test and demonstrate the method, and leaks were detected in all ...

  • Magnetic Flux Leakage Testing Equipment

    Electromagnetic detection is a very important non-destructive testing method and is widely used. Magnetic flux leakage testing is a magnetic method of nondestructive testing that is used to detect corrosion and pitting in steel structures, most commonly pipelines and storage tanks. The basic magnetic flux leakage ...

  • The Analysis of BTEX and MTBE Using Specially Modified Purge Traps

    The existence of underground storage tanks containing gasoline and other petroleum products has facilitated the need for routine testing to determine if there has been any leakage into surrounding soil and ground water. The analytical methods test for “BTEX”, which is an acronym for benzene, toluene, ethyl benzene, and xylene. In many instances, testing is not limited to these ...

  • Magnetic Flux Leakage Testing Equipment

    Electromagnetic detection is a very important non-destructive testing method and is widely used. Magnetic flux leakage is a magnetic method of nondestructive testing that is used to detect corrosion and pitting in steel structures, most commonly pipelines and storage tanks. The basic principle is that a powerful magnet is used to magnetize the steel. When used in combination with other methods, ...

  • Pipe Stopper Testing Mistakes

    In order to use a smooth flowing pipeline, we have to carry out a few tests with pipe stopper (a.k.a. pipe plug) as per EN 1610. By applying these tests, we can get results about leakages of the pipeline, if any. Or we can see how much pressure the line is holding. HOW CAN WE DO THESE TESTS? In our previous articles we have explained the Leak Test as per EN 1610 for sewer, ...

  • What’s New? Maximizing The Life Of Aging Metallic Pipelines With Modern In-Line Technology

    Maximizing the life of aging pipelines has long been a challenge in North America. Owners of large diameter water and wastewater infrastructure face particular condition assessment challenges, owing to factors such as financial constraints, environmental concerns and access restrictions, which compound the problem. While desktop studies can help identify pipes with a likelihood and consequence of ...

  • Locating Geomembrane Liner Leaks under Waste in a Landfill

    Abstract An Electrical Leak Imaging and Monitoring (ELIM SM) survey was used to locate leaks under 2.5 meters of stabilized waste in an active geomembrane-Iined landfill. The landfill is lined with two 2-mm thick HDPE geomembranes that are separated by a geonet drainage layer. The primary liner is covered with 600 mm of drainage sand and 2.5 meters of stabilized waste for a total ...
