2021 Amsterdam : A COST BENEFIT ANALYSIS OF PVC PIPES RECYCLING
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 : ALLOWABLE SCRATCH DEPTH HISTORY & RECOMMENDATIONS FOR PE PRESSURE PIPE
Author(s) : Chris Ampfer, Gene Palermo, Ernest & Oren Lever
This paper looks at the origin of the 10% allowable scratch depth rule for polyethylene (PE) pressure pipe developed
in 1971 and research that has been performed over the years since its inception to determine the validity of this
rule. The 10% rule has been used by natural gas pipeline operators since the 1970’s to...
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 : 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 : PIPE FOR FIRE EXTINGISHING DEVICE
Author(s) : Yoshikatsu NISHIDA, Yukihisa YAMADA, Masaya IWASAKI, Masaru TOMOBE, Yuichi KOUGA
By using polyethylene as the main material for this fire extinguishing device pipe, a
resin-made fire extinguishing device is developed that is maintenance-free for eight
years and can cope with the abnormal heat generation of lithium ion batteries.
In order to prevent the internal extinguishant from permeating and...
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...
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
package was made up of a set of standalone PowerPoint slides, providing information
on PVC-U and PVC-C pipe systems. Information on both general...
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 : RECYCLING COMMITMENT OF THE EUROPEAN PLASTIC PIPE INDUSTRY
Author(s) : Ludo Debever, Peter Sejersen
The European Plastics Strategy is a priority for the European Union. Recycling more post-
consumer plastics (PCRs) is paramount. That is why the Circular Plastics Alliance has been
established. The alliance gathers public and private stakeholders in the plastics value chains to
promote voluntary actions and...
2021 Amsterdam : SLOW CRACK GROWTH RESISTANCE OF REPROCESSED PVC
Author(s) : Andreas Frank, Mario Messiha, Günter Dreiling, Norbert Schuler, Jens-Martin Storheil, Erwin Mayrbäurl, Stuart Ramella, Frank Krause, Rudi Berning, Philippe Gabriëls, Alpay Aydemir, Thomas Koch, Florian Arbeiter, Gerald Pinter
The Cyclic Cracked Round Bar (CRB) Test has been applied to study the slow crack growth
(SCG) resistance of virgin, recycled, and reprocessed PVC-U. This fracture mechanical test allows a
quick ranking of the SCG resistance of PVC-U. A clear correlation between the K-value and the SCG
resistance has been elaborated....
