- 3D finite element simulation of EF PE Joints
Author(s) : Boujlal Adil 2012 Barcelona
(Electrofusion, Finite Element, Heat transfer, Interdiffusion, crystallisation and melting Kinetics, Micro-sampling) Electrofusion (EF) is widely used to join polyethylene (PE) components in the gas distribution networks. This paper provides experimental and 3D-finite element tool capable of reproducing the major...
- 3D FINITE ELEMENT SIMULATION OF ELECTROFUSION POLYETHYLENE JOINTS FOR GAS DISTRIBUTION
Author(s) : Chebbo Z., Boujlal A., Gueugnaut D., Vincent M., Tillier Y. 2012 Barcelona
(Electrofusion, Finite Element, Heat transfer, Interdiffusion, crystallisation and melting Kinetics, Micro-sampling) Electrofusion (EF) is widely used to join polyethylene (PE) components in the gas distribution networks. This paper provides experimental and 3D-finite element tool capable of reproducing the major...
- A Comparative analysis of the Carbon Footprint of Large Diameter Concrete and HDPE pipes
Author(s) : Cowle Matthew 2012 Barcelona
The increasing climatological effects of global warming have reinforced the importance of determining the greenhouse gas (GHG) emissions associated with different design solutions. The main aim of this study was to evaluate and compare the environmental impacts, in terms of Carbon Footprint, of two products heavily...
- A Methodology to Predict Critical Flaw Size in HDPE Piping and Joints in Nuclear Safety-Related Applications
Author(s) : Krishnaswamy Prabhat 2012 Barcelona
The ASME Boiler and Pressure Vessel Codes Committee (BPVC) has recently published Revision 1 of Code Case N-755 that describes the requirements for the use of High Density Polyethylene (HDPE) pipe for the construction of Section III, Division 1 Class 3 buried piping systems for service water applications in nuclear...
- A new approach for a fast and relevant evaluation of environmental stress-crack resistance in polyethylene grades
Author(s) : Lhost Olivier 2012 Barcelona
With the increase of the environmental stress crack resistance (ESCR) of polyethylene pipe grades, the need for a fast, cheap and relevant analytical tool able to evaluate this property is a must. A \"TC138\" working group is actively looking for accelerated test methods and is considering new approaches. Inside...
- A new point loading test method
Author(s) : Xiong Zhimin 2012 Barcelona
Resistance to slow crack growth (SCG) is one of the most important properties for HDPE pipe grades. Buried pipe with point loading is such a case, in which cracks initiate and grow slowly. One of the SCG evaluations is point loading test which verifies the service life for those pipes installed especially by...
- A NOVEL TECHNOLOGY TO REDUCE PRODUCTION COSTS FOR POLYOLEFINE SEWERAGE PIPES BY PHYSICAL FOAMING
Author(s) : Christian Schlummer & Rolf Heusser 2012 Barcelona
Polymer raw material costs for plastic pipe producers count for up to 80% of the total production costs. For non-pressure sewerage pipe application, one way to significantly reduce raw material consumption is to produce foam core multilayer pipes instead of solid wall products. A new development now allows to retrofit...
- A Solution For Drinking Water Networks: Emerging New Generation PE100 Pipes With Higher Chlorine Resistance
Author(s) : Rozental Magali 2012 Barcelona
(Polyethylene, Lifetime, Disinfectant, PE 100) Polyethylene is sensitive to chemical oxidation through the action of disinfectants used in drinking water, as explained in previous works. Based on accelerated ageing tests (high water temperature, chlorination, high pressure level), SUEZ-ENVIRONNEMENT defined a testing...
- A STUDY ASSESSING THE PERFORMANCE OF O-PVC IN PRESSURE PIPES
Author(s) : Catherine Michel, Johannes Akkerman 2012 Barcelona
Bi-axially oriented PVC (referred to as O-PVC) pressure pipes have outstanding mechanical properties. Tensile strength and E-modulus increase significantly with the stretching ratio. On the other side, the elongation at break decreases with the draw ratio. O-PVC pipes have also much better impact resistance especially...
- A study of electro-foaming fusion wrap fitting for Polyethylene sewer pipe
Author(s) : Hyoungsan Kye, Kyunghoon Joo 2012 Barcelona
A newly developed electro-foaming fusion (EFF) wrap for PE pipe is a fitting that wraps up the pipe and melts the PE sheet onto the pipe surface. The Electrofoaming fusion wrap adopts its foaming concept and welding technique for PE sewers and drainage pipes. The electro-foaming fusion wrap consists of a foaming...
