Since the introduction of polyolefins for pressure pipes, continuous improvements have been made to meet ever-higher demands on their performance and to expand their application window beyond their original scope, mostly based on new resin formulations. Today, we also continue to push the limit to provide better solutions. In this paper, we will highlight a route to produce biaxially oriented polyethylene and polypropylene pipes using our dedicated material formulations developed for this purpose. Continuous in-line biaxial pipe production line has been designed and constructed. The resistance to internal pressure, slow crack growth and chlorine dioxide resistance of pipes has been determined according to ISO 1167-1, ISO 13479 and ASTM F2023 respectively. These results were obtained by using 32mm and 63mm outer diameter pipes. This new generation of polyolefin pipes have shown a strong improvement over the whole property range, from internal pressure resistance to a two-fold improvement in chlorine dioxide resistance and a ten-fold improvement in slow crack growth performance. This solution is designed to meet today’s and the future’s demands. It has the potential to open up new application areas for polyolefin pipes.
