Comparing...

EFFECT OF CARBON BLACK DISTRIBUTION ON POLYETHYLENE PIPES

Author(s) : Suleyman Deveci, Nisha Preschilla, Birkan Eryigit 2018 Las-Vegas

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...

EFFECT OF CARBON BLACK, COMPOUNDING AND PIPE EXTRUSION ON THE SLOW CRACK GROWTH PENT TEST RESULT

Author(s) : Adriana Velasquez, Dr. Dane Chang, Dr. Siddharth Athreya 2018 Las-Vegas

EFFECT OF ECCENTRICITY ON THE MEASUREMENT OF HYDROSTATIC PRESSURE RESISTANCE OF PLASTIC PIPES

Author(s) : Suleyman Deveci, Birkan Eryigit, Senthil K. Kaliappan 2018 Las-Vegas

The effect of eccentricity on the failure time of pipes under hydrostatic pressure test has a significant magnitude that it can easily mislead the evaluation of pipes according to requirement of ISO 4427-2. Therefore, authors propose a maximum relative eccentricity limit of 0.015, even lower, for pipes being tested...

Last methodologies for fast evaluation of the SCG resistance on polyethylene pipe materials are analyzed in this work and compared with traditional PENT and FNCT tests. Strain Hardening (SH), Crack Round Bar (CRB) and Accelerated Creep Test (ACT) will be good alternatives for evaluating PE100RC resins. Moreover, SH...

EXTRUSION OF THICK WALL PIPES USING A NEW BIMODAL PE 4710/PE 100 RESIN

Author(s) : Vivek Rohatg, Gregor Hiesgen, Mark J. Lamborn, Ashish M. Sukhadia, Douglas E. Simpson, David W. Borrego, Pamela L. Maeger 2018 Las-Vegas

Maintaining dimensions within specifications is problematic for the extrusion of large diameter thick-wall polyethylene (PE) pipe (> 75 mm wall) due to sag caused by insufficient resin melt strength. However, sag can be controlled through careful resin selection and optimization of the pipe cooling process. This...

FATIGUE CRACK GROWTH TESTING IN CHLORINATED WATER AT ELEVATED TEMPERATURES - TEST EQUIPMENT AND TEST PROCEDURE

Author(s) : Joerg Fischer, Patrick R. Bradler, Reinhold W. Lang 2018 Las-Vegas

In the present paper, a novel test system for conducting fatigue crack growth (FCG) experiments under superimposed mechanical-environmental conditions is presented. FCG experiments were performed on a polypropylene (PP) grade and a short-glass fiber reinforced polyamide 66 (PA-GF) grade as model materials. The...

Field test of Glass fiber reinforced polyethylene pipe system at soften ground

Author(s) : Mitsuaki TOKIYOSHI, Gentaro TAKAHARA, Joji HINOBAYASHI, Toshinori KAWABATA, Takashi KURIYAMA 2018 Las-Vegas

Glass fiber reinforced polyethylene pipes and fittings are controlled for bending characteristics (Strength and stiffness) for vertical and axial directions of pipe by spiral cross winding method. Generally, to use this method, it takes much stronger for vertical strength than axials cause of extruded direction,...

GUIDELINES FOR CORRUGATED HDPE PIPES MANUFACTURED WITH RECYCLED MATERIALS FOR HIGHWAY CULVERT AND STORM DRAIN APPLICATIONS

Author(s) : Michael Pluimer, Richard Thomas 2018 Las-Vegas

Over the past decade, there have been several key research projects to evaluate the performance of corrugated HDPE pipes manufactured with post-consumer and postindustrial recycled materials for highway and railroad drainage applications. Three of these projects were recently completed and published (NCHRP Project...

HARMONIZING THE EUROPEAN HYGIENIC REQUIREMENTS

Author(s) : Ilari Aho, Volker Meyer, Peter Sejersen 2018 Las-Vegas

The lack of a cross-border acceptance of the approval of the hygienic requirements for plastic pipes systems is inefficient and expensive for the industry. The costs for testing of a pipe system range from a few thousand Euro to more than €30k /reference 3, 4/. The European Plastic Pipe and Fitting Association...

HDPE Pipe as a Solution to Utilities Operating on a Manage to Fail Basis

Author(s) : Sarah Eisenstat, Peter Dyke 2018 Las-Vegas

Many cities in the US are operating their water utility on a “manage to fail” basis, meaning they are replacing >100-year-old pipes at a cycle time of over 150 years. At this rate, most of the pipes will have failed before they can be replaced. Ft. Wayne, IN made the realization that PE pipe is the solution due...
