2001 Munich : Mechanisms of Slow Crack Growth in PE Pipe Grades
Author(s) : Beech, Ferguson, Clutton
Design of pipe systems for 50 year lifetimes depends on accelerated testing of pipe at
different temperatures and standard extrapolation methods for assessment of whether the
minimum required strength is achieved. Further acceleration is used in the notched pipe
test (NPT), which is a medium term (up to 1000 hour)...
2001 Munich : PE Pipeline Systems - The Big Success Story
Author(s) : Beech, Ducan, Millar
Polyethylene has been used for pipeline applications for nearly 50 years now. It has become
the prime material choice for gas and water distribution systems and many other applications
worldwide. This paper reviews the growth in the market for polyethylene pipe products for
both pressure and non pressure applications...
1998 Gothenburg : Key Properties of Plastics for Installation and Service
Author(s) : Beech
Pressure pipeline systems are a critical application for materials and demand high
levels of performance and reliability.
It is not by chance that plastics pipeline
systems have gained a considerable market share, particularly in the gas and water
utilities supply system. This paper briefly reviews the key properties...
1998 Gothenburg : The Advantages of a Silane Crosslinkable PE Liner for Pipelines
Author(s) : Wright, Burley
Advanced Engineering Solutions Limited (AES) and Colin Burley Associates have jointly developed and patented a Silane cross-linked polyethylene liner for the internal lining of pipelines, known as the (SPEX ) liner.
For a number of years Medium Density Polyethylene (MDPE) pipe has been extensively used as a liner to...

1992 Eindhoven : The Cooling Phase of Large Pipe Manufacture
Author(s) : Pittman, Whitman, Gwynn, Beech
Comprehensive operating data from a large-scale pipe cooling
lime are reported, including in-situ measurements of
temperatures within the pipe wall.
A finite element
simulation of cooling, coupled with gravity induced flow, or
slump, in the pipe wall is described. Computed temperatures
within the wall are compared...
