2018 Las-Vegas : Rehabilitation of abandoned dn1000mm steel pipe with PE100 in malaysia
Author(s) : KianLin Ng, WengKeong Tan, KumHoong Lou
Heavy and constant trucked container traffic combined with an accelerated ground settlement in a coastal reclaimed land caused a DN1000mm cement-lined mild steel water pipeline that crossed under it to sink by more than 6m from its original buried depth. This then caused the internal & external cement lining to crack....

In order to make it easy for the PVC pipe manufacturers to train their sales forces in a professional and consistent way across Europe and to give them a set of clear reference data, PVC4Pipes has taken a first initiative in developing a Training Toolkit, a set of Power Point slides, which provide information about...
2012 Barcelona : How much recycled PVC in PVC pipes?
Author(s) : J.Fumire and S.R.Tan
This paper demonstrates the excellent recyclability of rigid PVC and the strong possibilities of incorporating recyclate into foamed PVC pipes. Calculations show that it is the availability of rigid PVC recyclate, partly due to the long service lives of PVC pipes, which is the limiting factor in further extending the...
2012 Barcelona : Polyethylene Pipe and Hydroelectric Development
Author(s) : Sandstrum Steve
The term “hydroelectricity” conjures images of massive concrete dams and vast reservoirs that harness
the power associated with moving water. More recently, however, technological advancements and
environmental awareness have resulted in renewed interest in small-scale hydroelectric projects. These
