“Food is the new oil and gas” is a rather bold statement, but everyday more and more
people are concerned about food scarcity. Bringing irrigation to not productive lands will
change the lives of the community and if it can be done with a cost effective and the
most ecofriendly solution, even better.

HDPE pipes are used for standard pressurized water pipes, offering an excellent solution for safe transport of (drinking) water. The HDPE pipe market is growing globally. Especially in countries that suffer from water scarcity, surface water and water from rivers have to be used for drinking water supply. To guarantee...
2018 Las-Vegas : Extrusion of thick wall pipes using a new bimodal PE 4710/PE 100 resinAuthor(s) : Vivek Rohatg, Gregor Hiesgen, Mark J. Lamborn, Ashish M. Sukhadia, Douglas E. Simpson, David W. Borrego, Pamela L. Maeger
Maintaining dimensions within specifications is problematic for the extrusion of large diameter thick-wall polyethylene (PE) pipe (> 75 mm wall) due to sag caused by insufficient resin melt strength. However, sag can be controlled through careful resin selection and optimization of the pipe cooling process. This paper...
2018 Las-Vegas : Field test of Glass fiber reinforced polyethylene pipe system at soften groundAuthor(s) : Mitsuaki TOKIYOSHI, Gentaro TAKAHARA, Joji HINOBAYASHI, Toshinori KAWABATA, Takashi KURIYAMA
Glass fiber reinforced polyethylene pipes and fittings are controlled for bending characteristics (Strength and stiffness) for vertical and axial directions of pipe by spiral cross winding method. Generally, to use this method, it takes much stronger for vertical strength than axials cause of extruded direction,...
2018 Las-Vegas : Large diameter spiral wound pressure pipesAuthor(s) : Bülent Kuzkaya
Spiral wound pipes are becoming more and more important in larger diameter HDPE pipe production technology. The spiral wound structured wall pipes with profiles are already well known and used for several low or non-pressure pipe applications. This paper shows that spiral wound pressure pipes can fulfill the...
2018 Las-Vegas : Large pressure pipe system – Fully PE100Author(s) : Sverre Tragethon, Martin Andersson
Global mega trends push for investments in sewage treatment capacity & efficiency. A trend is to go for central regional treatment sites, typically remotely located from dense populated cities. This calls for high capacity pressure sewage transmission pipelines. Reliable operation is of course of paramount importance...
2018 Las-Vegas : Modern PE pipe enables the transport of hydrogenAuthor(s) : R.J.M. Hermkens, H. Colmer, H.A. Ophoff
To investigate the suitability of PE pipes for the transport of hydrogen on a specific industrial site, three topics were investigated. These topics are: the chemical resistance of PE to hydrogen, the permeation rate of hydrogen through PE and the electrofusion of PE pipes exposed to hydrogen. It can be concluded that...
2018 Las-Vegas : Pe100 large diameter water transmission pipelines take off in AsiaAuthor(s) : Andrew Wedgner, Muhammad Qasim, Arsenio Sembrano
Developments in material and pipe extrusion technology now enable converters to produce PE100 solid wall pipes of up to 2,800mm OD, but the use of such large diameters has been limited to industrial applications. This is now starting to change with water transmission pipelines of up to 1400mm OD being laid in the UAE...
