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 : DRAINAGE HANDBOOK STRUCTURAL DESIGN PROCEDURE FOR CORRUGATED POLYOLEFIN PIPEAuthor(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 PIPESAuthor(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 GUIDELINEAuthor(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 : LONG-TERM DURABILITY OF NEW POLYMER COMPOSITE VALVES FOR DRINKING WATER NETWORKSAuthor(s) : Jennifer Ravereau, Jose Teixeira Pinto, Malena Bernabeu, Jose Alacid, Jean-Philippe Le Goff, Frederic Mohier, Benjamin Rabaud
Drinking water network fittings such as valves are made of brass materials known to be robust over
long periods. Due to the gradual inflation metallic raw material costs, composite plastic valves have
grown in market share. Uncertainties remain, however, on their long-term reliability.
The aim of this work is to...
2021 Amsterdam : MODELLING THE MIGRATION FROM PVC-U PIPES INTO DRINKING WATERAuthor(s) : C. Losher and P.V. Mercea
In the framework of the German Environmental Agency (UBA) requirements of
plastic articles in contact with drinking water (KTW-BWGL-guideline), the
compliance is verified by comparing so-called “expected concentrations at tap”, C tap ,
of substances contained in the plastics with specific limits in drinking water...

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...

on PVC-U and PVC-C pipe systems. Information on both general...
2021 Amsterdam : PVC PIPES WITH SUPERIOR ROOT INTRUSION RESISTANCEAuthor(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 : PVC-O DN800: EFFICIENT TRANSFORMATION FROM SOIL TO IRRIGATED LANDAuthor(s) : Ignacio Muñoz
“Food is the new oil and gas” is a rather bold statement, but everyday more and more
people are concerned about food scarcity. Bringing irrigation to not productive lands will
change the lives of the community and if it can be done with a cost effective and the
most ecofriendly solution, even better.
This case study...
2021 Amsterdam : RECENT DEVELOPMENTS IN INTEGRAL JOINT RESTRAINTSAuthor(s) : Guido Quesada
An important breakthrough for belled PVC pipe was made around 2006, when the
