  • Maintaining a pressure reducing valve: 5 things to check

    Like your car, your body and nearly every appliance you own, control valves require regular maintenance to continue working efficiently. However, due to budget and time constraints, we don’t always give our valves the TLC they need to perform at their best. Unfortunately, ignoring pressure reducing valves can mean serious ...

  • 99% of Oil from Leaking tanks remediated - Case study

    Spills and leaks from domestic and commercial oil tanks are a very common occurrence, caused either by the refilling of tanks or as the result of leaks. Very  often old metal tanks corrode and start leaking oil onto the ground around the tank. Also the tanks themselves become covered in dried hydrocarbons and become significantly discoloured, even black. Spilled oil can seep into the ground, ...

  • Preventing sinkholes: avoiding costly repairs

    Examining the causes of sinkholes and how Deep Trekker is aiding in preventing costly repairs and unwarranted closures. When it comes to preventing sinkholes, we must first understand how and why they appear. Armed with this knowledge, we can then take proper action to thwart the sudden appearances of these, costly craters. Sinkholes slowly develop over time in and around areas ...

  • Case Study - Siemens Industrial Turbomachinery AB

    Problem Two large gas turbines (approximately 25m x 12m x 10m) were installed in an industrial area nearby an office building. The gas turbines generate a tonal noise component at around 2700Hz caused by the inlet channel blades pass frequency. This tone imposes a more stringent noise requirement on the supplier, forcing noise reducing actions being made on the turbine. ...

  • What is an anechoic chamber and how quiet can it be?

    One of the things that we often talk about when we’re running our CPTC (Cirrus Product Training Courses) is how our hearing works and we often end up talking about how, if there’s no ambient sound, we can feel uncomfortable and can become disoriented very quickly. One of the best (or maybe the worst) places to experience this is in ...

  • Transient frequency response based leak detection in water supply pipeline systems with branched and looped junctions

    The transient frequency response (TFR) method has been widely developed and applied in the literature to identify and detect potential defects such as leakage and blockage in water supply pipe systems. This type of method was found to be efficient, economic and non-intrusive for pipeline condition assessment and diagnosis, but its applications so far are mainly limited to single and simple ...

  • Hoffman Specialty PRV Troubleshooting

    Q.  How do I test a spring pilot? A.  The easiest way to test a pilot operated valve is to disconnect the pilot line and observe the pilot’s operation. Keep in mind you are handling steam. Use proper safety precautions. When you turn the adjusting nuts in, the pilot valve should open and steam should shoot out the end of the tube. When you ...

  • Multiple-fault detection in water pipelines using transient-based time-frequency analysis

    Pipe faults, such as leakage and blockage, commonly exist in water pipeline systems. It is essential to identify and fix these failures appropriately in order to reduce the risk of water pollution and enhance the security of water supply. Recently, transient-based detection methods have been developed for their advantages of non-intrusion, efficiency and economics compared to traditional ...

  • Integrity management: how direct assessment is improving pipeline inspection

    Oil and gas pipelines have been around for well over a century, and some of the earliest constructed are still in service today.  Although early pipelines were made of wood, and in the past few decades plastics and composite materials have increased in popularity, the vast majority of pipelines in service today are constructed with steel.  Like any pipe material, steel pipe has its ...
