The current paper presents a scientific approach for a fracture mechanics lifetime prediction based on Cyclic Cracked Round Bar (CRB) Tests....

LIMITS ON THE SLOW CRACK GROWTH RESISTANCE EVALUATION FOR THE PE100 AND PE100RC POLYETHYLENE RESINS

Author(s) : Carlos Domínguez, Nuria Robledo, Rafael A. García-Muñoz 2016 Berlin

With the last advances and improvements in the polyethylene resins used for pipe application, new methods for evaluating long-term mechanical properties need to be introduced. Standard PENT and FNCT tests needs more than one year for characterizing the new PE100RC grades with the consequent thermal ageing problems....

LOCATABLE PIPE TECHNOLOGY THROUGH GLOBAL COLLABORATION

Author(s) : Allison Crabtree, Yogesh Kumar, Jessie Allen 2016 Berlin

This paper presents a technology for locating plastic pipe buried underground. The technology was developed for the water market in India and, through intra-company collaboration, has been introduced to the water and gas markets in the United States. Information regarding product technology and end-use considerations...

LONG LENGTH HDPE PIPES FROM NORWAY – FROM PROBLEM TO A SUCCESS STORY

Author(s) : Miroslav Stanimirov 2016 Berlin

Long length pipes, which are these days often used as high quality and cost efficient solution in various types of projects, are actually product of a problem that PE pipe installers were facing in early days of plastic pipe business. That problem was low reliability of PE pipe joints. The only logical solution was to...

Long term influence of defects in butt fusion joints on PE100 pipes and NDT detection of them

Author(s) : Jörg Wermelinger, Oliver Hein 2016 Berlin

More and more a strong desire is noticeable for Non Destructive Testing (NDT) of welded PEjoints. The objective is to determine the long term performance of plastic piping systems made from PE100. To assess the impact of “mostly known defects“ on the long term performance of a welding, well-defined flaws have to...
