Accelerated Testing Method to Estimate the Lifetime of Polyethylene Pipes
… to choose the best polymeric material for a specific application. Additionally, it helps material producers to design, manufacture, test, and modify a polymeric material more rapidly. In the case of polymeric pipes, previous studies have shown that there are two possible time-dependent failure …

Mineral Scale Buildup on Lined Versus Traditional Polyethylene Pipe Materials Subjected to Mine Influenced Waters
… Acid mine drainage (AMD) is a common type of MIW characterized by low pH. Release of untreated MIWs like AMD to surface waters, for example, can lead to problems such as a sedimentation and siltation, undesirable changes in pH and/or precipitation of metals and salts, and addition of …

Advancing Potable Water Infrastructure through an Improved Understanding of Polymer Pipe Oxidation, Polymer–Contaminant Interactions, and Consumer Perception of Taste
… unaware of how premise and buried polymer water pipes deteriorate and sorb/ desorb organic contaminants during normal operations and following water contamination events. These knowledge–gaps also prevent infrastructure managers from producing drinking water that optimizes mineral content for …

Condition assessment of polyethylene pipeline systems
… state of in-service naturally aged polyethylene (PE) buried pipes and to define procedures or techniques available to facilitate the condition assessment programme of PE pipelines systems. The primary goal of this study was to establish a better understanding of the ageing process in commercial …

Butt fusion welding of polyethylene pipes
… extensively used in the joining of polyethylene (PE) pipes by the water and gas industries. This welding process although deceptively simple, is rather poorly understood, with much of the initial developments being of a rather empirical nature. The Water Research centre (WRc) have funded the …

Development Of A Performance Analysis Framework For Water Pipeline Infrastructure Using Systems Understanding
… data and analyzing it to monitor and predict the performance of their distribution systems. Many mathematical models have been developed to guide repair and rehabilitation decisions in the past but remain largely unused because of low reliability. This is because any effort to build a decision …
