2021 Amsterdam : POLYPROPYLENE PIPE IN DEMANDING HYDRONIC HEATING APPLICATIONS
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
2018 Las-Vegas : Discover: plastics
Author(s) : Davidovski Zoran
To get a deeper insight in why plastic pipes systems in some cases are deselected by designers, installers and users, European Plastics Pipes and Fittings Association (TEPPFA) initiated a research including interviews in four pilot countries: Poland, France, Germany and the UK. The first phase was concentrating on...
2018 Las-Vegas : Extrusion of thick wall pipes using a new bimodal PE 4710/PE 100 resin
Author(s) : Vivek Rohatg, Gregor Hiesgen, Mark J. Lamborn, Ashish M. Sukhadia, Douglas E. Simpson, David W. Borrego, Pamela L. Maeger
Maintaining dimensions within specifications is problematic for the extrusion of large diameter thick-wall polyethylene (PE) pipe (> 75 mm wall) due to sag caused by insufficient resin melt strength. However, sag can be controlled through careful resin selection and optimization of the pipe cooling process. This paper...
2018 Las-Vegas : Innovations in production of corrugated pipes
Author(s) : J. Vlachopoulos, M. A. Lupke
A very tight-fitting bell-and-spigot inline coupler, minimizing the gap between connecting pipe segments, and a space efficient pulsating corrugator, requiring just three mold block pairs, were developed.
The author of a recent article in New York Times  claims that some 300 Billion dollars are needed to repair the...
2018 Las-Vegas : The use of temperature, lubrication, and supplied hydraulic pressure in the production of oriented PVC pipe
Author(s) : Jie Feng, Michael Petr, Jeff Wenzel, Mark Mirgon, Sam Crabtree, Alan Nakatani
Through tensile tests, simulated orientation, tribology, and finite element analysis, this study explored the effect of temperature, lubrication and applied hydraulic pressure in the PVC orientation process. It was demonstrated that tight control of these parameters is critical in a continuous PVC orientation process...
2016 Berlin : Asset management of polyethylene gas networks
Author(s) : Ian Aldridge, Declan Robinson, Dave Smart, Chris Reed, Martyn, Greig, Trevor Stafford, David Christie-Lowe, Alec Erskine
For the UK polyethylene (PE) gas pipe network, the first installations now exceed 40 years in the ground, with an original design life of 50 years. It was thus timely to review the current condition and performance history of these first generation PE materials. A major 4 year project was started in 2010 to examine...
2016 Berlin : Flexible plastic solution for district heating pipes
Author(s) : Dr. Anton Vasilenko
In today’s world a lot of energy is wasted. More than 50 % of the energy is lost on its way to the customer. The fundamental idea of modern district heating is to recycle heat that otherwise would be lost and to use renewable sources to heat homes. In other words: a market place for green heat that reduces consumption...
2016 Berlin : Flexible pre-insulated thermoplastic reinforced pipes for city heat network
Author(s) : Ostrovsky Dmitry, Shmelev Andrey
Pre-insulated thermoplastic reinforced pipes were developed for East European heating networks with elevated operating temperatures and pressures. In contrast to monolayer plastic pipes, high modulus aramid mesh reinforcement used in thermoplastic reinforced pipes allows significantly to increase both operating...
2016 Berlin : Main drivers and barriers for plastic pipes in Europe
Author(s) : Davidovski Zoran,
The European Plastics Pipes and Fittings Association (TEPPFA) and it Application Group Civils working group initiated a new project at the beginning of 2015, to find a way of improving the communication and promotion of TEPPFA and its projects to the industry. This project was divided into the two phases with the...
