HDPE pipes are used for standard pressurized water pipes, offering an excellent solution for safe transport of (drinking) water. The HDPE pipe market is growing globally. Especially in countries that suffer from water scarcity, surface water and water from rivers have to be used for drinking water supply. To guarantee a safe drinking water supply, the water has to be disinfected properly. One of the most efficient disinfecting agents is chlorine dioxide. It has advantages over chlorine, since it does not affect taste or smell of water. The disadvantage of this disinfecting agent is the associated accelerated degradation of polyethylene pipes.
In this paper work on gaining further insight into the mode of failure and the route we have designed to validate potential solutions is highlighted. The route taken consists of two stages, one small-scale evaluation to perform a screening of potential solutions and a second stage of a long-term evaluation of pipe performance. The small-scale evaluation method was developed after close examination of both pipe and small-scale aged specimen.

HDPE Pipe holds a dominant position in several markets in North America: natural gas distribution, oil patch, mining, landfill and geothermal. So why are polyethylene’s municipal water and wastewater market shares so much lower than these other industries? How has the polyethylene industry been successful in growing...

In the rural commune of Ait Bayoud, Morocco, two of the most remote villages in the area, Ilguiloda and Izgouaren, live with water scarcity. To meet their water needs, women and children walk several kilometers to the nearest spring each day, often multiple times a day. Consequently, children cannot attend school...

HDPE pipe can be relatively easily scratched during the manipulation on the site, which is especially true for the marine pipelines. Installing the scratched marine pipe with the S bend method presents a risk and repair methods are usually performed. Currently, there is no standard defining the repair procedure, in...

The City of Miami Beach owns and operates a 54-inch sanitary sewage PCCP force main (FM) that was built in 1977. This FM is the only transmission pipeline for conveying about 22 million gallons per day (MGD) of raw sewage to the wastewater treatment plant. In 2012, the City identified structural deficiencies in the...

The Point Load Test (PLT) [ 1, 2] was designed to simulate the SCG (slow crack growth) failure initiated by a rock pressing into the exterior wall of a polymer pipe. Today’s PE materials sustain long PLT testing times, due to its high SCG resistance design. Consequently, an accelerated “PLT+” with the support of...

Maintaining dimensions within specifications is problematic for the extrusion of large diameter thick-wall polyethylene (PE) pipe (> 75 mm wall) due to sag caused by insufficient resin melt strength. However, sag can be controlled through careful resin selection and optimization of the pipe cooling process. This paper...

Many cities in the US are operating their water utility on a “manage to fail” basis, meaning they are replacing >100-year-old pipes at a cycle time of over 150 years. At this rate, most of the pipes will have failed before they can be replaced. Ft. Wayne, IN made the realization that PE pipe is the solution due to its...
