2018 Las-Vegas : 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
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 paper...
2018 Las-Vegas : Innovative design of the atlanta braves baseball field
Author(s) : Jim Goddard, Issam Khoury, Mark Heinlein
The Atlanta Braves Major League Baseball team built a new stadium north of Atlanta, Georgia. The field drainage design required the removal of 75mm (3 inches) of rainfall an hour and a system for warming or cooling the field using air blown through the drainage system and field profile using heat from pipe buried...
2018 Las-Vegas : PE100-RC in large diameter sea outfall applications
Author(s) : Mark Yu, Dongyu Fang, Peck Tze Kang, Amos Tay , Fan Liu
Large diameter pipe was introduced in refineries and petrochemical plant, desalination plant and power plant for water intake and sea out fall in the past decade. PE100-RC material was selectedfor its excellent balance of superior bi-modal stress crack resistance and consistent high stiffness modulus.
2018 Las-Vegas : The use of temperature, lubrication, and supplied hydraulic pressure in the production of oriented PVC pipe
Author(s) : Jie Feng, Michael Petr, Jeff Wenzel, Mark Mirgon, Sam Crabtree, Alan Nakatani
Through tensile tests, simulated orientation, tribology, and finite element analysis, this study explored the effect of temperature, lubrication and applied hydraulic pressure in the PVC orientation process. It was demonstrated that tight control of these parameters is critical in a continuous PVC orientation process...
2016 Berlin : Big data, big difference
Author(s) : Nick Mark, Eric Bridgstock, David Carey
An insight into a unique approach to the management of electrofusion and butt fusion joint quality on polyethylene pipelines. The presentation will reference experience and learnings from a system that has already been used in the field to great effect (see Abstract) and a new approach to butt fusion (see enclosed...
2014 Chicago : The Effects of Dual Cooling on the Rapid Crack Propagation Performance of Polyethylene Pipes
Author(s) : Mark J. Lamborn, Pam L. Maeger, Rick E. Kunc, Vivek Rohatgi, Paul J. DesLauriers, Ashish M. Sukhadia
Dual cooling is a post-extrusion cool down process employed for polyethylene (PE) pipe, whereby either water or ambient air is forced through the pipe bore following extrusion, in order to accelerate cooling. The primary benefits offered by the dual cooling process are increased production rates and reduced resin...
2012 Barcelona : Performance and sustainability advantages of PVC sewer pipes in australia
Author(s) : Alan Whittle, Nigel Jones and Mark Heathcote
PVC has been used successfully for sewer and sanitary drainage pipes in Australia
for over 40 years. It is the predominant material for these applications. The reason
for this success is the superior, all round performance of PVC piping systems
compared to the various alternatives. Equally important has been the...
