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.
