AN EXAMINATION OF FIELD FAILURES OF PLASTIC PIPING SYSTEM COMPONENTS IN POTABLE WATER APPLICATIONS

摘要

Disinfectants in potable water, such as chlorine and chlorine dioxide, can impact the performance of plastic piping system components. In this paper, field failures of plastic piping components exposed to potable water are examined. Analysis of the oxidative and mechanical initiation and propagation mechanisms leading to failure is performed. Field and laboratory samples are also compared to assess the test methodologies that are available to evaluate the impact of disinfectants on plastic piping systems.
