2021 Amsterdam : MODIFIED PLAIN STRAIN GROOVED TENSILE TEST TO EVALUATE LARGE DIAMETER PE PIPES
Author(s) : Thomas R. Kratochvilla, Patrick Grünbeck, Christoph Bruckner, Raimund Eremiasch, Harald Wilhelm, Mario Vukelja
In the last decades pipe dimensions of extruded PE pipes have reached new orders
of size. Today, PE pipes with outer diameters of up to DN/OD 3500 mm are produced
and used for pressure pipe applications like seawater intake/discharge, outfall, sewage
and industrial process piping systems.
To test the long-term...
2021 Amsterdam : ONLINE ENGINEERING TOOLS FOR DESIGN AND FIELD ENGINEERS
Author(s) : Dustin Langston
The design and installation of polyethylene systems can be complex, specifically due to
the many applications and environmental conditions that surround those systems.
Online design tools have been developed to address this complexity and the various

2018 Las-Vegas : Field test of Glass fiber reinforced polyethylene pipe system at soften ground
Author(s) : Mitsuaki TOKIYOSHI, Gentaro TAKAHARA, Joji HINOBAYASHI, Toshinori KAWABATA, Takashi KURIYAMA
Glass fiber reinforced polyethylene pipes and fittings are controlled for bending characteristics (Strength and stiffness) for vertical and axial directions of pipe by spiral cross winding method. Generally, to use this method, it takes much stronger for vertical strength than axials cause of extruded direction,...
2018 Las-Vegas : Innovations in production of corrugated pipes
Author(s) : J. Vlachopoulos, M. A. Lupke
A very tight-fitting bell-and-spigot inline coupler, minimizing the gap between connecting pipe segments, and a space efficient pulsating corrugator, requiring just three mold block pairs, were developed.
The author of a recent article in New York Times  claims that some 300 Billion dollars are needed to repair the...
2018 Las-Vegas : Large diameter spiral wound pressure pipes
Author(s) : Bülent Kuzkaya
Spiral wound pipes are becoming more and more important in larger diameter HDPE pipe production technology. The spiral wound structured wall pipes with profiles are already well known and used for several low or non-pressure pipe applications. This paper shows that spiral wound pressure pipes can fulfill the...
