2018 Las-Vegas : The use of temperature, lubrication, and supplied hydraulic pressure in the production of oriented PVC pipe
Author(s) : Jie Feng, Michael Petr, Jeff Wenzel, Mark Mirgon, Sam Crabtree, Alan Nakatani
Through tensile tests, simulated orientation, tribology, and finite element analysis, this study explored the effect of temperature, lubrication and applied hydraulic pressure in the PVC orientation process. It was demonstrated that tight control of these parameters is critical in a continuous PVC orientation process...
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 : Stormwater Boxes – A Solution for Climate Change Impact on Water Management
Author(s) : Martina Sandholzer, Michael Jerabek, Christophe Salles, Günter Dreiling
Due to the combination of climate change impact, resulting in many regions of the world having a heavier and unpredictable rainfall, together with increased urbanization, the possibility for lower natural infiltration of the water into the soil has created a real challenge for storm water management systems. Forecast...
2012 Barcelona : The Evolution of Corrugated HDPE Pipe Materials
Author(s) : Michael Pluimer
Corrugated high density polyethylene (HDPE) pipe has been used in various
drainage applications in the United States for nearly 50 years. First developed in
smaller diameters primarily for agricultural applications, the product quickly found its
way into the highway industry as an edge drain to increase pavement...
2010 Vancouver : A service Life Assessment of Corrugated HDPE Drainage Pipe
Author(s) : Michael Pluimer
The service life of our nation’s infrastructure has become a topic of increasing focus 1n recent years. While above-ground infrastructure deterioration is readily apparent, the infrastructure beneath the surface can be much worse and yet is often ignored until it is too late. Since culverts and other buried structures...
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...
2001 Munich : Development and Testing of Magnetic Detectable PE Pipe
Author(s) : Jarnecke, Mamoun
Magnetic detectable polyethylene (PE) pipe has been developed for the gas distribution
system that has permanent detection for locating underground piping. Magnetic detectable
PE pipe differs from normal PE pipe by the addition of magnetic particles in the PE resin,
which are magnetized in a sinusoidal pattern during...
1995 Edinburgh : Experimental validation of an advanced computer model for electrofusion
Author(s) : Grigory, O'Donoghue, Mamoun
Measurements of temperature,
power input, and pressure of the molten PE at
the pipe-coupling interface in 4-, 6-, and 8-inch
(1 14-, 168- and 219-rnm)' electrofusion (EF)
couplings were made using instrumented
experiments during the fusion cycle. The high
temperature properties of several medium and
