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 : FLOWABLE FILL FOR PLASTIC PIPE
Author(s) : Amster Howard
Flowable fill is used for many applications, but mainly for pipe trench embedment and
backfill. There are three ways that using flowable fill can be kind to the environment.
Because flowable fill is self-leveling and has a strength greater than the native soil, the
trench cross section can be minimized. This means...
2021 Amsterdam : INVESTIGATION OF THE QUALITY CHARACTERISTICS OF POLYAMIDE 12 PIPE WELDS
Author(s) : M. Eckes & Dr. B. Baudrit, Dr. M. Troughton & D. Wylie, H. van Laak & J. Fritz
Unplasticized polyamide 12 (PA-U12) is increasingly being used in pipe applications,
especially in the gas sector. However, the material behavior in the usual quality tests for
pipe welds has not yet been thoroughly investigated.
For this reason, two research institutes, worked in cooperation with a manufacturer
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 : 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 : 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 : Risk Assessment of Non-Intentionally Added Substances (NIAS) in potable water
Author(s) : Dr Ruediger Liske, Dr Tobias Eltze, Dr Tania Weyland, Marie-Laure Bertet
The migration of NIAS (Non-Intentionally Added Substances) into potable water is a
recurring topic for the distribution of cold and warm drinking water and related materialsindustry. These substances are chemical compounds that are present in drinking water
contact materials but have not been added during the...
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...
