ACCELERATED INVESTIGATION OF THE EFFECT OF CHLORINE DIOXIDE ON THE LONG-TERM FAILURE BEHAVIOR AND THE MATERIAL AGING OF POLYETHYLENE FOR RAISED TEMPERATURE RESISTANCE

Author(s) : A. Redhead, A. Frank, G. Pinter 2012 Barcelona

Keywords: polyethylene for raised temperature resistance, chlorine dioxide, oxidative resistance, degradation, embrittlement Two different polyethylene pipe grades for raised temperature resistance (PE-RT) and one PE100 grade were investigated concerning their resistance to chlorine dioxide. Conventional test methods...

ACCELERATED MATERIAL TESTING WITH CYCLIC CRB TESTS

Author(s) : Andreas Frank, Anita Redhead, Thomas Kratochvilla, Heinz Dragaun, Gerald Pinter 2012 Barcelona

Key words: Polyethylene, pipe, test method, lifetime, slow crack growth For a qualitative characterization of the slow crack growth resistance of polyethylene pipe grades several test methods are available. Especially for modern pipe grades these test methods exceed practical time frames and new acceleration methods...

Addressing India’s food needs with modern PE micro-irrigation systems

Author(s) : Dasgupta Chanchal 2012 Barcelona

Keywords: Food supply, micro irrigation, water scarcity, polyethylene compound. India’s population is growing rapidly and today it is the second most populous country in the world. Over 80% of its scarce water supply is used to irrigate crops, mainly by inefficient flood irrigation methods fed by open water...

AN ASSESSMENT OF THE COMPETITIVENESS OF PVC PIPING SYSTEM. THE TOTAL COST OF OWNERSHIP APPROACH

Author(s) : Alessandro Marangoni 2012 Barcelona

keywords: water, total cost of ownership, installation costs, Italy, Germany This paper is based on a research done on behalf of ECVM by Althesys Strategic Consultants about the competitiveness of some PVC products (window profiles, pipes, flooring) applying the Total Cost of Ownership (TCO) methodology. The TCO...

An Enhanced Reinforced Thermoplastic Pipe (RTP) for High Temperature Applications in the Upstream Oil and Gas

Author(s) : Kallum Morland and Blaine Weller 2012 Barcelona

An enhanced reinforced thermoplastic pipe for higher temperature (RTP-HT) applications has been introduced utilizing a high performance grade of PE material (Bimodal HDPE-RT) to cater to oil and gas pipelines that experience continuous service temperatures of up to 82°C (180°F). The primary use of RTP-HT has been in...

Analysis of slow crack initiation of old polyethylene resins by means of an elasto-visco-plastic rheological model: experimental and numerical approach

Author(s) : Boujlal Adil 2012 Barcelona

(Polyethylene, Long term behavior, Rheology, Slow Crack initiation time) Predicting PE failure mechanisms needs suitable models in order to describe accurately both material behavior and damage processes. In this area GDF SUEZ’ Research & Innovation Division carries out an in-depth study to determine on the one...

Approach to the solution for removing “sharkskin” of PE pipe through extruder die modification

Author(s) : Chi Yongsheng 2012 Barcelona

Key words: shark skin, extrusion, die head, polyethylene pipe It was found that the ratio between the length of the land of the extruder head (L) and the gap between the die and the mandrel (T) has an effect on the pipe appearance during extrusion process. The present paper discusses the relevance between shark skin...

ARE METHODS FOR TIGHTNESS TESTING FIT FOR PURPOSE?

Author(s) : Lars Jacobsson, Hans Andersson and Linda Karlsson 2012 Barcelona

Problems sometimes occur in tightness testing of plastic pipelines using pressurized water and accounting for the diametrical expansion, particularly so for larger sizes and higher pressure rating. Pipelines that are in fact tight enough for acceptance are rejected when first tested. A study consisting of two parts...

BEST ENVIRONMENTAL PRACTICE PVC PIPES AND FITTINGS FOR THE GREEN BUILDING INDUSTRY

Author(s) : Nigel Jones, George Macovaz, Alan Whittle, and Mark Heathcote 2012 Barcelona

Key Words: PVC, Green Building Until recently the Australian green building rating tool effectively created a disincentive to use PVC pipe. The PVC industry in general and the PVC pipe industry in particular worked with the Green Building Council of Australia (GBCA) and associated stakeholders to establish an...

Bimodal PE Pipe Proves an Enduring Solution for Gas Pipe In New Mexico

Author(s) : Serrano de Rivera Angela 2012 Barcelona

In the ultimate field environment for testing polyethylene (PE) gas pipe, New Mexico Gas Company initiated an internal evaluation of bimodal PE4710 pipe in 2005. These extensive laboratory and field evaluations were vitally important to ensure that the material could be easily fused to the existing pipe network and in...
