PIPE INSPECTION AND STANDARDS | PROCESSING
The system was able to detect even small leaks by monitoring pressure and flow. The K-fold approach in the machine-learning algorithm located the leakage in different variations made in the experimental model in terms of pressure, leak size, pipe cross-section and the profile level of the pipe network. The researchers also made a comparison with other machine-learning algorithms from recent research in terms of accuracy, size of the opening for the leak, type of experimental model used, and variables considered to locate the leakage. “This is the first research kind of work that shows
the average accuracy of 78% to locate leakage based on the real-time experimental data in a loop network using the K-fold approach,” they concluded. In future, the researchers want to apply the method to a real case and potentially use alterna- tive machine-learning algorithms to achieve higher efficiency. The research appeared in the Indian Journal of Science and Technology.
Monitoring roll-out Eni of Italy – in collaboration with SLB – is to deploy its Eni vibroacoustic pipeline monitoring system (E-VPMS) more widely. The technology is a vibroacoustic wave detec- tion system that can provide real-time analysis, monitoring and leak detection. It was internally developed by Eni to increase safety, reliability and sustainability of pipelines. Its subsidiary, Enivibes, will bring the proprietary pipeline integrity technology to the market through SLB’s ability to scale deployment – through opera- tions in more than 100 countries. The alliance covers the deployment of E-VPMS technology for pipelines that transport liquid hydrocarbons or water and enables detection of product loss through external events – such as attempted theft or accidental impact, corrosion-
related leaks, and land movement caused by earthquakes or landslides. The alliance will bring E-VPMS to both onshore
and offshore pipelines – and with it, the ability to monitor the integrity of even the oldest assets, said Eni.
UV weathering Weathering is also a key concern for plastic products such as pipes. At last year’s K show, Atlas Material Testing Solutions showed its latest weathering test instruments for plastic materials and products. These included the Xenotest 440 – a weathering instrument for use with a variety of materials that features a twin-lamp test chamber using the company’s XenoLogic technology to enable faster testing. Powered by two 2,200W xenon lamps, it can reach 2-sun irradiance levels for significantly shorter test times.
Also on display was its high-capacity Suntest
XXL+, which meets all common international weathering standards for polymers and coatings, and the Suntest XLS+, a compact benchtop instrument for weathering and colour lightfastness testing of plastics. Both instruments have been designed to test 3D specimens. The release of a new sealed lamp for the established Atlas Ci4000 and Ci4400 Weather- Ometers was also highlighted. The new design simplifies installation by incorporating all assembly elements – xenon-arc lamp, inner glass filter, outer glass filter and associated hardware – into a single, factory-sealed unit. It also offers virtual monitoring of materials in the
shape of View (Virtual Inspection and Evaluation of Weathering). Using View allows clients to interact remotely with technicians and experts while observing the effects of weathering on their specimens in real time. The next View generation is WXView II, a web-based application that allows
