2014 Chicago : Liquid Crystal Polymer in the Manufacture of Plastic Pipes
Author(s) : Dongming yu, Linan Chen
This article is the impact study on general plastic pipe performance when using Liquid Crystal Polymer (hereinafter LCP) and LCP alloy, the soaking extrusion in-situ composite technique and the coat-molding technique for plastic pipe extrusion. It turns out that the high barrier property of TLCP can help us...
2012 Barcelona : High Temperatures on PE Pipes for Water Supply Pressure Verification
Author(s) : Chen Zenggui
For PE pipes for water supply installed in the summer, the pipeline’s temperature under the sun exposure can influence the properties of the pipe. If you carry out the pressure tests directly, it can result in damage to the pipeline. So we conducted a detailed analysis and research on the influence of exposure to the...

2001 Munich : Ductile Failure and Delayed Necking in PE
Author(s) : Jivraj, Sehanobish, Dun, Damen, Wu, Zhou, Chen, Shulkin, Chudnovsky
Analysis of polyethylene (PE) pipes ductile failure (ballooning) suggests that it is directly
related to the delayed necking phenomena and time to ductile failure of PE pipe can be
evaluated as the time to delayed necking. The necking in polyethylene (PE) is studied
under displacement control (ramp test) and load...
1995 Edinburgh : Rotational Moulding of Plastics Pipes and Pipe Fittings
Author(s) : Crawford, Xu, Spence
Currently plastic pipes and
fittings are manufactured by extrusion or
injection moulding. However, in certain
circumstances there are considerable
advantages to be gained by using rotational
moulding for these types of products. In
particular, rotationally moulded products are
stress-free, can have greater than...
