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 : ANALYSIS OF PVC AND CPVC BLENDS
Author(s) : Saleem Shakir
Unplasticized formulations based on Poly(Vinyl Chloride) (PVC) and Chlorinated Poly(Vinyl
Chloride) (CPVC) resins offer technical solution to pressure piping systems that find extensive use in
residential and industrial applications. Building upon the desirable properties of the vinyl monomer, the
chlorine content 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 : MODELLING THE MIGRATION FROM PVC-U PIPES INTO DRINKING WATER
Author(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...
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 : PVC-O DN800: EFFICIENT TRANSFORMATION FROM SOIL TO IRRIGATED LAND
Author(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 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 : 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....
2021 Amsterdam : TESTING AND EVALUATION OF NANOADDITIVES IN U-PVC PIPES
Author(s) : E. Boccaleri, L. Palin, G. Rombolà, M. Milanesio
In the last decades, research on nanostructured materials as additives for plastics
involved several polymeric matrices, but only limited studies and publications
involve PVC. In this work, the context of rigid application of PVC (U-PVC) for pipes
application was targeted, in order to test and evaluate the structural...
