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...
2014 Chicago : Standardization of Data Capture for Fusion Operations
Author(s) : Dennis Jarnecke
The Pipeline and Hazardous Materials Safety Administration (PHMSA) published the final rule establishing integrity management requirements for gas distribution pipeline systems on December 4, 2009 (Distribution Integrity Management Programs - DIMP). The regulation requires operators, such as natural gas distribution...
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...
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
