Author(s) : A. Marangoni
The quality of infrastructures is a key driver for maximizing the performance of the
utilities networks and minimizing the environmental impacts associated with their
operation. The water and sewer pipes are key network elements to guarantee a
satisfactory service to the citizens. Their end-of-life management is an...
2021 Amsterdam : A METHODOLOGY TO DETERMINE CHARPY IMPACT STRENGTH OF NOTHCED SPECIMEN CUT FROM PLASTICS PIPES
Author(s) : Li, Yanjun, Xiang, Aimin, Xu, HaiyunBeijing, Xie, Jianling, Ho, Kinman, Xu, HaiyunBeijing
It is necessary to evaluate the impact resistance of plastics pipes as they have the potential to be
damaged by hitting or colliding during storage, transportation and installation. As a well-established
test method, the Charpy impact strength of unnotched test pieces cut from thermoplastics pipes is
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 : 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 : MULTILAYER POLYMER PIPES – THE INFLUENCE OF RESIDUAL STRESS ON FATIGUE LIFETIME
Author(s) : Lukas Travnicek, Pavel Hutar, Jan Poduska, Andreas Frank, Florian Arbeiter, Jaroslav Kucera, Jiri Sadilek, Gerald Pinter, Lubos Nahlik
The application of recycled material in pressure piping systems has been considered
lately – it was suggested, that the recycled polyethylene could be used as a part of a
multilayer pipe together with virgin material. This type of pressure pipes is not availableon the market yet, so their properties can be only...
2021 Amsterdam : MUTUAL RECOGNITION OF THE CERTIFICAT ION SCHEMES IN EUROPE
Author(s) : Horst Stimmelmayr, Peter Sejersen
The voluntary certification scheme for plastic multilayer piping systems for hot and cold
drinking water inside buildings is a joint effort of two key European organizations. It was
initiated in close cooperation with the Brussels based European trade association of
plastic pipe and fittings manufacturers, TEPPFA....
2021 Amsterdam : PLASTIC PIPES FOR WATER DRAINAGE IN RAIL- AND MOTORWAY TUNNELS – A MAJOR CHALLENGE
Author(s) : Florian Arbeiter, Tobias Schachinger, Stefanie Eichinger, Gisbert Rieß, Michael Stur, Michael Steiner, Florian Saliger
Plastic pipes are of outstanding importance for the distribution of potable and
process waters, oil and gas, as well as for sewer and waste water disposal. However,
plastic pipes are also used in many other technical areas. Especially in European
countries with mountainous regions, such as Austria, Switzerland, Italy...

Author(s) : Steve Sandstrum, Chris Ziu
The market for high performance polypropylene (PP) piping systems in North America continues to
evolve. Generally, PP piping systems have performed exceptionally well in a variety of challenging
HVAC, industrial and plumbing applications. As a result, the engineering community in North America is
2021 Amsterdam : PVC Pipes TRAINING PACKAGE: 2020 UPDATE!
Author(s) : Sylvie Famelart, Vincent. Stone
In order to deliver to the market reliable and consistent information about PVC and the
different PVC pipe solutions, a Training Package was developed a few years ago. The

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...
