  • Flow Rate Measurement in full Pipes using the Transit Time Method

    Particularly in large diameters the relevance of water volume measurement is growing. The challenge with cooling water or fresh water processes is to generate accurate flow recordings or to document and to control individual consumptions and withdrawal quantities. Flow detection, however, particularly in large diameters is highly demanding. In such cases the transit time measurement thanks to its ...

  • Oil Sampling Best Practices

    Obtaining a representative oil sample from a closed loop lubrication system is essential to any good oil analysis program. As oil analysis programs become more standardized for routine monitoring, especially within equipment warranty support programs, equipment makers provide more sampling points on new equipment. These ...

  • Biocorrosion in drinking water pipes

    Copper is widely used in drinking water distribution systems due to its relatively low cost and favorable mechanical properties. However, copper corrosion may generate copper concentrations exceeding the thresholds prescribed by international drinking water standards. In-situ measurements performed in an actual system found that the copper mass released under flowing water conditions (pipe ...

  • On the prediction of underground water pipe failures: zero inflation and pipe-specific effects

    The prediction of pipe failures in water distribution systems is an essential planning tool for water companies. Previous methods focus on the prediction of either future failure numbers or aspects of pipe condition. However, most of these only predict at the level of large pipe groups (of similar characteristics) and often cannot provide uncertainty bounds. Here, a new statistical method is ...

  • Review of rehabilitation strategies for water distribution pipes

    Effective rehabilitation strategies for water pipes play a very important role in both sustaining the reliability of water distribution systems and reducing costs. Pipe breakage prediction models provide a platform for effective rehabilitation strategies. The strength of the rehabilitation strategies is just an extension to those predictive models. There are different techniques and methods for ...

  • Application of unidirectional flushing in water distribution pipes

    In this study unidirectional flushing (UDF) was conducted to improve the effectiveness of deposit removal from internal pipe walls and to provide information on pipe networks to enable operators to implement flushing in field. Four ductile cast iron pipes with epoxy-lined and cement-lined were selected for the practice of UDF. Water pressure was measured using a data logger equipped with a ...

  • A practical decision scheme for the prioritization of water pipe replacement

    Most water distribution networks are assemblies of buried elements which makes their diagnosis complex and requires implementing an asset management (AM) policy of actions performed in the short, medium and long terms. To implement such an AM, decision makers must diagnose the condition of the asset by developing specific tools for establishing priorities between assets and plan the actions ...

  • Organic compounds migrating from plastic pipes into water

    Case studies were carried out to identify potential chemical contaminants migrating to drinking water from polyvinyl chloride (PVC) or polyethylene (PE) pipes, available on the Polish market. Analyses were carried out by gas chromatography (GC) coupled with mass spectrometry (MS). Analysis of organotin compounds in water in contact with PVC pipes from different manufacturers found variability: ...

  • Preventing & Thawing Frozen Pipes

    A “how-to” guide on preventing and thawing frozen pipes. As temperatures drop below freezing around the country, it’s important to be informed of the cold weather’s effect on your water pipes. When temperatures are below freezing, pipes in unheated areas are subject to freezing causing messy, and often expensive issues. Just one burst pipe running at 4-8 ...

  • Quadratic approximations for pipe friction

    This paper develops quadratic approximations to the classical models of Darcy–Weisbach and Hazen–Williams for frictional head loss in water pipes. Key elements of the technique are selecting the approximation domain and minimizing the relative error. A comparison for individual pipes over a range of diameter, roughness, and Reynolds number showed that the approximation provides ...

  • Characteristics of pipe-scale in the pipes of an urban drinking water distribution system in eastern China

    Pipes that carry drinking water have gradually aged. Events occurring with increasing frequency, such as substandard water quality in residential taps, red water, and black water, reveal the deterioration of the chemical stability of a drinking water distribution system (DWDS). Pipes in the DWDS serving City S, located in eastern China, were sampled to analyze the concentration and ...
