  • Transient tests for locating and sizing illegal branches in pipe systems

    In pipe systems illegal branches can take away remarkable water resources with negative effects from both the economic and technical points of view. Difficulties in pointing out illegal branches by means of steady-state pressure and discharge measurements are mainly due to the fact that, of course, such systems are not active according to a regular time schedule. In this paper the possibility of ...

  • Quantitative pipe condition assessment with Pipe Penetrating Radar

    Abstract Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in / 450mm) non-ferrous (reinforced concrete, vitrified clay, PVC, HDPE, etc.) pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids ...

  • Completing Condition Assessments using In-pipe GPR as Pipe Penetrating Radar

    Abstract This paper describes the development of Pipe Penetrating Radar (PPR), the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in / 450mm) non-metallic (concrete, PVC, HDPE, etc.) underground pipes. The method uses two or more high frequency GPR antennae carried by a robot into ...

  • Looking in the Pipes of Climate Adaptation Finance

    I’ve often thought about buying a fixer-upper. There is a certain allure to the idea of reviving the charm of an old home and giving it new life. But I’m also acutely aware that behind the walls and underneath the floors, I’m likely to find a tangle of old plumbing—potentially riddled with leaks, an assortment of pipes and parts, and confusing twists and turns. These ...

  • Leak behaviour in pressurized PVC pipes

    The correct definition of the leak law, i.e. the relationship between the leak outflow, the total head at the leak and other relevant parameters such as the pipe material, can seriously affect the accuracy of the numerical models used for the management of water distribution systems, either if they are used to forecast the leakage reduction by pressure management or to locate and size the leaks ...

  • Combined application of Pipe Penetrating Radar and LIDAR for large diameter pipe inspection

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR), a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in./450mm) non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. Light Detection and Ranging (LIDAR) has become an accepted method for ...

  • Bulk Storage and Piping Case Study

    Background: This major steel manufacturer was founded in 1900 in and established the first formal research department in the steel industry in 1910. It grew through the development of specialty steels and new technology. Among the many "firsts" was the development of continuous rolling technology. This company holds more U.S. patents than any other specialty steel company. ...

  • Use of Air Bag System for Instrumentation of Lateral Load Tests on Previously Installed Pipe Piles

    A simple and inexpensive air bag system for allowing measurement of the deflected shape of laterally loaded piles has been developed. The air bag system may be used for hollow piles that have already been installed. The system includes an inclinometer casing that is held against the inner wall of the pile by an inflated air bag. Tests on small- and large-diameter steel pipe piles at two different ...

  • Sewer-Main Collection Pipe Joint Infiltration Testing and Life Cycle Cost Analysis

    ABSTRACTResearch ProjectsMajor members of the sewer-main pipe manufacturing industry and the University of Houston have completed and published the results of the following two research projects: The Sewer-Main Collection Pipe Joint Infiltration Testing research project that measured the water infiltration rate of water-tight designed 30-inch pipe joints. The joint tightness testing was ...

  • Anomaly pre-localization in distribution–transmission mains by pump trip: preliminary field tests in the Milan pipe system

    In this paper, the reliability of transients due to pump trip as a powerful tool for the pre-localization of anomalies in real pipe systems is tested. The examined pipe system is part of the one supplying the city of Milan, Italy and is managed by Metropolitana Milanese SpA (MM). The characteristics of such a system can be considered as intermediate between those of classical transmission mains ...

  • Robot Device for Pipe Inspection - Case Study

    In 2005, Pure Technologies (Pure), a provider of various structural monitoring and leak-detection technologies, set about to develop a pipeline assessment tool that could monitor and report on the condition of pre-stressed concrete cylinder pipes (PCCP) utilized in municipal water and sewer systems. The tool’s competitive advantage would be accurate assessment decoupled from the need to ...

  • Diagnosis of pipe systems by the SLE: first results

    In this study, an algorithm is presented for pipe system diagnosis. The algorithm is the Successive Linear Estimator (SLE) previously used in groundwater hydrology to estimate the hydraulic proprieties of soils. The SLE is an iterative cokriging-like technique which provides statistically the best unbiased estimates and quantifies the associated uncertainty. In this paper the algorithm has been ...

  • The challenges of creating a 250,000-pipe model for Miami-Dade

    Earth Tech has used InfoWorks WS to develop a record-breaking all-mains model of Miami-Dade’s water supply system in order to achieve an accurate representation of the entire distribution process. The new dynamic model covers the whole of the 250,000-pipe network, as well as all the associated facilities. 'One of the challenges was that we had to model the whole system - every single pipe,' says ...

  • 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 (based on ...
