2014 Chicago : An Assessment of the Approach to Validate Polyethylene Pipe in Potable Water Systems
Author(s) : Dr. Ken Oliphant, Patrick Vibien, Dr. Michael Conrad, Sarah Chung
A new methodology has been developed to validate the performance of polyethylene piping materials in potable water applications. The methodology is based on several research programs which examined a standardized accelerated test methodology (ASTM F2263 Standard Test Method for Evaluating the Oxidative Resistance of...
2014 Chicago : Polyethylene Pipe Repair
Author(s) : Dennis Jarnecke, Tony Kosari
The purpose of this research was to conduct a thorough evaluation of a structural reinforcing system (patch) for the repair and/or reinforcement of mechanically damaged polyethylene pipes in an effort to establish permanency of the repairs and determine the life expectancy. MDPE and HDPE pipe specimens with machined...
2006 Washington DC : S4 Critical Pressure and Critical Temperature
Author(s) : Maeger, Vanspeybroeck, Lamborn, Mamoun, Leevers, Oliphant
As polyethylene pressure pipes enter the global marketplace under an ever-wider range of
operating conditions, there is increasing emphasis on their rapid crack propagation
performance. It is important that both producers and end-users are able to rely on the
robustness of the rapid crack propagation test results and...
2004 Milan : Environment Factors in Performance Forecasting of Plastic Piping Materials
Author(s) : Chung, Couch, Kim, Vibien, Oliphant
Environmental factors are known to significantly impact the oxidative failure mechanism of
materials. For example, the chlorine present in potable water as a disinfectant is an oxidant
that has been reported to impact the failure mechanism of materials in potable water
applications. In this paper, the relationship...
2001 Munich : Assessing Material Performance in Chlorinated Potable Water Applications
Author(s) : Vibien, Couch, Oliphant, Zhou, Zhang, Chudnovsky
The chlorine present in potable water as a disinfectant has been reported to reduce the
lifetime of some plumbing system components. In this study the nature of the failure
mechanism of a commercial cross-linked polyethylene (PEX) pipe material exposed in the
laboratory to chlorinated potable water is examined. The...
