2021 Amsterdam : APPLICATIONS OF HDPE PIPING TO SUPPLY WATER TO RURAL VILLAGES IN MOROCCO
Author(s) : Donald Swen, Leanne Pichay, Nicholas Vallin, Alice Wu, Jim Johnston
In the rural commune of Ait Bayoud, Morocco, two of the most remote villages in the area,
Ilguiloda and Izgouaren, live with water scarcity. To meet their water needs, women and
children walk several kilometers to the nearest spring each day, often multiple times a
day. Consequently, children cannot attend school...
2021 Amsterdam : WHY PA-U12 HIGH PRESSURE PIPES DO NOT CARE ABOUT “ROCK ́N ́ SHARD” IN VIEW OF PAS 1075
Author(s) : Hermann van Laak, Jan Heimink, Mario Messiha, Andreas Frank, Christoph Bruckner, Thomas Kratochvilla
For high pressure pipes above maximum operation pressure of 10 bar, this paper
emphasizes PA-U12 as the easy to install alternative to steel. It underlines the superb
performance of PA-U12 pipes for alternative installation techniques without need for a
separate mechanical protection. An unplasticized polyamide 12...
2018 Las-Vegas : Chlorine dioxide resistant HDPE mechanism, analytical tools and solutions
Author(s) : M. Boerakker, S. van Mierloo, D. v. Beek, R. Schipper, P. Voets, M. Soliman, K. Jacobson, D. Lukes, B. Rabaud, F. Zraick
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 : Design and qualification of PA-PERT pipe for oil and gas transportation
Author(s) : Liang Yu, Akshay Ponda, Dane Chang
Following the development of US shale oil and gas production since 2007, the demand for thermoplastic pipes with better corrosion resistance, and lower installation and operation cost than carbon steel pipe, has been growing significantly. Nylon 12 has been qualified for hydrocarbon transportation in offshore flexible...
2018 Las-Vegas : Determination of the slow crack growth resistance of PA12 pipe grades
Author(s) : Mario Messiha, Andreas Frank, Isabelle J. Berger, Jan Heimink, Hermann van Laak, Florian Arbeiter, Gerald Pinter
Since the last decade polyamide 12 (PA12) has been successfully introduced as material for SDR 11 gas piping systems up to 18 bar, representing itself as an attractive alternative to steel pipes for high-pressure applications. Practical experience has confirmed that beside the higher strength, PA12 pipe grades also...
2018 Las-Vegas : Development of polyethylene ball valve to pursue robustness
Author(s) : Ryosuke Nagahisa, Shinichi Katoh
We investigated the possibility of using a greaseless polyethylene (PE) ball valve by applying a coating on it to improve the valve’s robustness. In order to verify the valve’s operability, we performed initial-operating-torque, abrasion, and dust tests on both grease-applied and coatingapplied ball valves. These...
2018 Las-Vegas : Effect of carbon black distribution on polyethylene pipes
Author(s) : Suleyman Deveci, Nisha Preschilla, Birkan Eryigit
Pipes with inhomogeneous CB distribution showed 80% less elongation than pipes with homogenously distributed CB. Polymer domains with less or no CB (windows) showed delamination from the polymer matrix as the material elongated, finally leading to fracture much earlier than expected.
In this study, we investigated the...
2018 Las-Vegas : Large pressure pipe system – Fully PE100
Author(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 hydrogen
Author(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 Asia
Author(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...
2018 Las-Vegas : Polyehthylene/aluminum/polyehthylene composite pipe for fuel gas application
Author(s) : Baiqian Li, Jun Wang, Lixian Zheng, Xiaoyi Peng, Lei Wang, Yu Cui, Guozhi Xu
Polyethylene/Aluminum/Polyethylene (PAP) composite pipe has the advantages of corrosion resistance, limited joints and convenient installation. Nowadays PAP pipes are widely used in indoor gas conveyance. But a number of companies encounter difficulties in installing gas meter in users’ house as well as billing. Some...
