PRODUCT ENVIRONMENTAL FOOTPRINT (PEF) METHOD COMPARED WITH ENVIRONMENTAL PRODUCT DECLARATIONS (EPDS)

Author(s) : Ludo Debever, Peter Sejersen, Carolin Spirinckx 2018 Las-Vegas

Until today there are various ways of demonstrating the Environmental Performance of products, such as Life Cycle Assessments (LCA), Life Cycle Impact Assessments (LCIA), Environmental Performance Declarations (EPDs). The methods to obtain the result, however, can vary from country to country and can be interpreted...

Production of Potable Water Pipes for Chile Using the Inline Extrusion Process

Author(s) : Douglas D. Keller 2018 Las-Vegas

This paper describes the successful collaboration of a regulator, pipe producer and PE material supplier to demonstrate the conformance of pipes produced with inline extrusion compound to the requirement of the Chilean water pipe normative NCh398/1.Of2004 and also to the performance requirements of ISO 4427:2007 parts...

QUALITY ASSURANCE ON WELDED JOINTS WITH THE MECHANISED LINEAR SHEAR TEST (LST)

Author(s) : Juergen Wuest, Benjamin Baudrit, Frank Dorbath, Christopher Pommer 2018 Las-Vegas

A testing apparatus for determining the mechanical properties of electrofusion and heated tool sleeve welded joints with the mechanized linear shear test (LST) was developed. The LST-apparatus allows the recording of the force as a function of the extension / shear length. It has been proved that the linear shear test...

REHABILITATION OF ABANDONED DN1000MM STEEL PIPE WITH PE100 IN MALAYSIA

Author(s) : KianLin Ng, WengKeong Tan, KumHoong Lou 2018 Las-Vegas

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...

SENSITIVITY OF STRAIN HARDENING MODULUS TO MOLECULAR STRUCTURE OF POLYETHYLENE

Author(s) : Suleyman Deveci, Senthil K. Kaliappan, Joel Fawaz, Umesh Gadgoli 2018 Las-Vegas

A series of non-commercial bimodal high density ethylene-α-olefin copolymers with systematically controlled molecular parameters over a wide range that would result in extremely low and high strain hardening modulus were prepared and tested Strain hardening modulus has been published as a standard test method (ISO...

SLOW CRACK GROWTH RESISTANCE OF NON-VIRGIN POLYMERS

Author(s) : Andreas Frank, Isabelle J. Berger, Mario Messiha, Carl-Gustaf Ek, Norbert Schuler, Jens-Martin Storheil, Erwin Mayrbäurl, Steve Heeley, Frank Krause, Lodewijk Niemöller, Philippe Gabriëls, Yogesh S. Deshmukh, Florian Arbeiter, Thomas Koch, Gerald Pinter 2018 Las-Vegas

In order to improve the circular economy of polymers in terms of sustainability and reduced carbon footprint, the increased use of recyclates has become a topic of major importance. Due to their long design lifetimes, pipe applications represent an excellent opportunity to create added value to non-virgin polymers. In...

SQUEEZE-OFF AND REROUNDING OF PLASTIC PRESSURE PIPES

Author(s) : Juergen Wuest, Mirko Wenzel, Andreas Bilsing, Peter Postma, Werner Wessing 2018 Las-Vegas

Within the scope of a DVGW (German Technical and Scientific Association for Gas and Water) research project the technology of squeezing-off for PE pipes at operating pressures higher than 1 bar and the extension to new materials with higher operating pressures were investigated. For this purpose the tightness of the...

STUDY ON PARAMETERS AFFECTING DURABILITY OF POLYETHYLENE PIPES FOR HOT WATER APPLICATION

Author(s) : Hirofumi Kyutoku, Kazuhisa Igawa, Hidekazu Honma, Sakiko Fukunishi, Hiroyuki Nishimura 2018 Las-Vegas

There are mainly two grades of polyethylene pipes for hot water supply and heating. The excellent molecular structure polyethylene resins having resistance to stress crack growth are used because hot water is flowed for a long time in both polyethylene pipes. Furthermore, various additives are mixed to prevent the...

STUDY ON THE RESISTANCE TO EXTERNAL PRESSURE TEST METHODS OF PLASTIC INSPECTION CHAMBERS

Author(s) : Zhang Wei, Wei Ruoqi, Zhou Minghong, Zhou Mingwei, 2018 Las-Vegas

This article gives a brief introduction of plastic inspection chambers in China. It focuses on the formulation of China's national standard for plastic inspection chambers and conducts the theoretical analysis and data validation of the key technical metrics in the standard for the following three tests: the...

SUSTAINABLE CONSTRUCTION - ENVIRONMENTAL IMPACT ANALYSIS OF INTEGRATING RECYCLED HDPE INTO CORRUGATED PIPING

Author(s) : D.W. Currence, B. Sauer 2018 Las-Vegas

Society’s call for improved stewardship of natural resources and public funds continues to grow. Combined with the challenges facing public infrastructure has resulted in the broadened expectation for sustainable and resilient materials and products to serve in these future public infrastructure needs....
