2021 Amsterdam : DESIGN OF LARGE DIAMETER BURIED PIPES
Author(s) : Anders Andtbacka, Peter Sejersen
In the late nineties a study of the behavior of buried thermoplastics pipes was carried
out. The project had input and participants from both the plastic pipe industry as well as
from external organizations. Six external leading experts in the field of pipeline design,
not necessarily plastics pipes design, have been...
2021 Amsterdam : DRAINAGE HANDBOOK STRUCTURAL DESIGN PROCEDURE FOR CORRUGATED POLYOLEFIN PIPE
Author(s) : Joe Babcanec, P.E., Dan Currence, P.E.
The newly released Drainage Handbook provides complete guidance on corrugated
polyolefin pipe. Perhaps the biggest contribution this new handbook makes to the
advancement of both HDPE and PP corrugated plastic pipe is the design procedure
presented. The design procedure reflects the industry’s recommended practice for...
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
factors that must be considered. These online tools used widely in...
2021 Amsterdam : PVC PIPES WITH SUPERIOR ROOT INTRUSION RESISTANCE
Author(s) : Argnani Claudio, Ing. Gianpaolo Contarini
...Clogging of the pipes can be experienced in sewer systems after a short period of
service, due to the intrusion of roots from plants and trees. Plants, and in particular
their roots, are attracted by the water flowing inside the pipes. These roots will strain
the connections between pipes, in particular the sockets...
2021 Amsterdam : RIGHT STABILIZATION AND QUICK MEASUREMENT OF GEL CONTENT IN PE-XA PIPES
Author(s) : Alireza Sahaf Amin, Dr. Gholamreza Pircheraghi
PE-Xa pipes used in the hot water supply are required for high mechanical strength and high creep
resistance at high temperature. Because of the higher cross-link degree of PE-Xa pipes as compared
with other crosslinked pipes methods , these pipes which are made by peroxide crosslinking have
better performance in the...
