2021 Amsterdam : CHEAPER AND BETTER NETWORKS REALISED WITH PRACTICAL DESIGN SOFTWARE
Author(s) : Andreas Moerman, Flip van der Valk, Mirjam Blokker KWR, Tjakko Haaijer, Jan Vreeburg,
Drinking water companies with ageing networks are facing vast amounts of drinking
water network reconstructions during the coming decades. This development coincides
with the energy transition, which puts pressure on the available space underground.
These external drivers give drinking water companies an opportunity...
2021 Amsterdam : DESIGN OF A DISTRIBUTED STRAIN MONITORING SYSTEM FOR HDPE WATER PIPELINES CROSSING AN EARTHQUAKE FAULT
Author(s) : Peter Hubbard, Linqing Luo, Andrew Yeskoo, Kenichi Soga, Krista (Moita) Araica, Gus Cicala, Marshall McLeod
Seismically active faults pose a risk to buried water pipelines that can be complicated
to quantify. Fault type, slip rate, pipeline geometry, and soil conditions all factor into a
complex soil-pipeline interaction. For critical pipelines that cross faults, high-density
polyethylene (HDPE) has become an attractive...
2021 Amsterdam : DEVELOPMENTS IN NORTH AMERICAN CONDUIT PRACTICES
Author(s) : Tom Stewart, Richard Hicks, Patrick Vibien, Lance MacNevin
Arguably, broadband technologies have become as vital to society as water delivery, waste removal
and energy distribution. However, the role of plastic conduit in broadband is often overlooked within
the piping industry and society in general. HDPE conduit is an essential component to the build -out of
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 : FRACTURE MECHANICS TECHNIQUES IN LARGE DIAMETER PVC PIPES
Author(s) : Antonio Rodolfo Jr., Vanderley M. John
Unplasticised (U-PVC) and modified (M-PVC) pipes used in irrigation and infrastructure
applications, outside diameter 326 mm, were evaluated according to various fracture mechanics
methodologies, including fracture toughness (stress intensity factor KC and energy release rate GC,
both at fracture), essential work of...
2021 Amsterdam : FROM MULTILAYER LAMINATES TO INDUSTRIAL PIPE APPLICATIONS – A GUIDELINE
Author(s) : Gerald Pinter, Johannes Wiener, Florian Arbeiter, Abhishek Tiwari, Otmar Kolednik
For pipe applications, catastrophic failure due to crack growth has to be prevented
by all means. Techniques to develop new and even tougher pipe materials are explored
in this contribution. The aim is to create a multi-layer architecture, that exhibits high
toughness as well as damage tolerance towards sharp notches....
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 : RECENT DEVELOPMENTS IN INTEGRAL JOINT RESTRAINTS
Author(s) : Guido Quesada
An important breakthrough for belled PVC pipe was made around 2006, when the
first versions an integral joint restraint were released, after about two years in
development. This type of restraint comprises a casing, usually made of metal such
as ductile iron or stainless steel, a rubber seal, and a “C” grip ring,...
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...
