2018 Las-Vegas : A new flexible jointing method of plastic (PE) pipes
Author(s) : Yilaing He, Tianjun Zhang
A new electrofusion PE belt is developed by reinforcing it with various layers of steel mesh. It’s of sandwich structure, consisting of steel mesh reinforcement, heating wire and polyethylene. One or more layers of steel mesh is encapsulated in the middle, and heating wire is embedded onto “inner side” of the belt....

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 Environmental Temperatures on PE Water Pipe Application
Author(s) : Zhang Zhihao, Zheng Xiaoming
PE pipes have been used for many years in China. However, due to lack for engineering experience, some failure or leakages caused by PE pipe axial shrinkage have occurred in practice. In particular leaks were observed at or near the joints between metal and PE pipes. Suspecting that the cause of the leakage was the...

2004 Milan : Pressure Design of Steel Mesh Reinforced Plastics Pipes
Author(s) : Sun, He, Zhang
Steel mesh reinforced plastic pipe is an innovative type of pressure pipe which is composed of
plastics with a steel mesh encased. Due to the big differences in respective mechanical
properties of the two materials, the stresses sustained by them also differ greatly when the pipe
is subject to load. The methods...
