Current-generation polyethylene pipe should have solid, long-term performance for drinking water applications, according to a study announced July 27.
The Plastic Pipe Institute Inc. released the study, which was conducted by Jana Laboratories Inc. of Aurora, Ontario.
Current models project that high-performance PE piping materials can, conservatively, provide more than 100 years of resistance to chlorine and chloramine-treated potable water systems, when properly designed and installed, PPI's Executive Director Tony Radoszewski said in a news release.
The analysis covered the potential effects of chlorine and other disinfectants added to drinking water, durability, oxidation aggressiveness, temperature and pressure stress. Jana Laboratories used samples from Indiana, Florida, North Carolina and California.
Irving-based PPI said PE pipe has been used for potable water for more than 50 years, with good results. In the drinking water market, PE competes against PVC, copper, ductile iron and concrete.
The PE pipe industry has worked for more than a decade to develop accelerated test and analysis methods to help long-term performance in specific end-use environments, according to Radoszewski.
Ken Oliphant, executive vice president of Jana Laboratories, said current-generation materials are expected to have excellent longevity across the majority of end-use applications and good performance in very aggressive end-use environments.
