2016 Berlin : Can PE and PVC gas distribution pipes withstand the impact of sustainable gases?
Author(s) : René Hermkens, Ernst van der Stok, Johannes de Bruin, Jeroen Weller
The replacement of fossil fuels like natural gas by sustainable gases such as biogas and hydrogen can mitigate global warming. There has been some debate about the impact of sustainable gases on the materials used in the gas grid. An extensive study of the behaviour of PE, PVC, POM and rubber materials was therefore...
2016 Berlin : Design of plastic sewage products in PVC
Author(s) : Maarten Kruijer
To ensure the structural integrity of long term load bearing thermoplastic (like PVC or HDPE/PP) components, the time-dependent behavior of the raw (thermoplastic) material needs to been assessed and integrated in the design procedure. This paper describes how the time-dependent material behavior can be integrated in...
