2021 Amsterdam : A TRADE ASSOCIATION EXPLOREDAuthor(s) : Drew Mueller, Peter Dyke
HDPE Pipe holds a dominant position in several markets in North America: natural gas distribution, oil
patch, mining, landfill and geothermal. So why are polyethylene’s municipal water and wastewater
market shares so much lower than these other industries? How has the polyethylene industry been
successful in growing...
2021 Amsterdam : APPLICATIONS OF HDPE PIPING TO SUPPLY WATER TO RURAL VILLAGES IN MOROCCOAuthor(s) : Donald Swen, Leanne Pichay, Nicholas Vallin, Alice Wu, Jim Johnston
In the rural commune of Ait Bayoud, Morocco, two of the most remote villages in the area,
Ilguiloda and Izgouaren, live with water scarcity. To meet their water needs, women and
children walk several kilometers to the nearest spring each day, often multiple times a
day. Consequently, children cannot attend school...
2021 Amsterdam : CHALLENGING THE 10% WALL THICKNESS RULE FOR HDPE MARINE PIPELINESAuthor(s) : Ilija Radeljic, Ebbe Smith
HDPE pipe can be relatively easily scratched during the manipulation on the site,
which is especially true for the marine pipelines. Installing the scratched marine pipe
with the S bend method presents a risk and repair methods are usually performed.
Currently, there is no standard defining the repair procedure, in...

The City of Miami Beach owns and operates a 54-inch sanitary sewage PCCP force
main (FM) that was built in 1977. This FM is the only transmission pipeline for
conveying about 22 million gallons per day (MGD) of raw sewage to the wastewater
treatment plant. In 2012, the City identified structural deficiencies in the...

Arguably, broadband technologies have become as vital to society as water delivery, waste removal
and energy distribution. However, the role of plastic conduit in broadband is often overlooked within
the piping industry and society in general. HDPE conduit is an essential component to the build -out of
5G cell...
2021 Amsterdam : DRAINAGE HANDBOOK STRUCTURAL DESIGN PROCEDURE FOR CORRUGATED POLYOLEFIN PIPEAuthor(s) : Joe Babcanec, P.E., Dan Currence, P.E.
The newly released Drainage Handbook provides complete guidance on corrugated
polyolefin pipe. Perhaps the biggest contribution this new handbook makes to the
advancement of both HDPE and PP corrugated plastic pipe is the design procedure
presented. The design procedure reflects the industry’s recommended practice for...
2021 Amsterdam : THE ADVANTAGES OF PE 100 GLOBAL CASE STUDIESAuthor(s) : Youssef Taha, Rainer Kloth
In the early fifties, the first Polyethylene for the use in pipes was produced. Since then, the use of
Polyethylene piping systems has spread rapidly around the globe to serve in various applications. In
order to demonstrate the versatility and benefits of PE100, several companies founded in 1999 an
association...
2018 Las-Vegas : Extrusion of thick wall pipes using a new bimodal PE 4710/PE 100 resinAuthor(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 : HDPE Pipe as a Solution to Utilities Operating on a Manage to Fail BasisAuthor(s) : Sarah Eisenstat, Peter Dyke
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 to its...
