2021 Amsterdam : A COST BENEFIT ANALYSIS OF PVC PIPES RECYCLINGAuthor(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 PIPESAuthor(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
determined...
2021 Amsterdam : ANALYSIS OF PVC AND CPVC BLENDSAuthor(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...

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 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 : 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...

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...

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....

The design and installation of polyethylene systems can be complex, specifically due to
the many applications and environmental conditions that surround those systems.
Online design tools have been developed to address this complexity and the various
factors that must be considered. These online tools used widely in...

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...
