2014 Chicago : The Influence of Additive Levels on PE-Xa Pipe Performance
Author(s) : Zhang SiLiang, Zhang ShuangQuan, Guo XiaoLing, Ren YunHong, Wang MingKe
This article describes the effect of additive, light and high temperature on PE-X pipe’s performance. By additive amount changes, will be have different influence to pipe’s brittleness resistance, bending strength, and aging resistance. As cross-linking agent’s content increasing, bending strength enhanced, but...
2012 Barcelona : Effect of the residual stresses on the slow crack growth
Author(s) : Pavel Hutař, Martin Ševčík, Jaroslav Kučera, Michal Zouhar, Robin Luky, Luboš Náhlík
Using linear elastic fracture mechanics a new methodology for a lifetime assessment of internally pressurized polymer pipes was developed. The concept is based on the numerical calculation of stress intensity factors for pipes under different loading conditions in combination with experimentally determined creep crack...

application in China, describes recent technical development, such as raw...
2010 Vancouver : PE100+ Association’s Quality Promotional Activities in China
Author(s) : R.Bresser
PE has been so successful in the gas and water distribution pipe markets of Europe largely
because of its proven quality and reliability compared to other pipe materials. This has in part
been due to the work of organisations such as the PE100+ Association in supporting high quality
specifications and auditing...
