Worlds first “green pipe” wins innovation award
QuakeWrap Inc., a Tucson, Ariz.-based designer, supplier and installer of FRP products for repair, won an American Society of Civil Engineers (ASCE) Innovation Award in the category of “Best Value – Green Engineering” for its StifPipe® technology – the world’s first “green” and sustainable pipe.
Contest entries fit four categories – innovative business models and technologies, Internet of Things (IoT), green engineering, and resilience – each sponsored by top engineering-related firms. In the coming months, industry leaders from Walt Disney Imagineering, Hatch Mott MacDonald, KCI Technologies Inc., and Pennoni will host the winners for special events.
The pipe was invented by QuakeWrap President Dr. Mo Ehsani, a Professor Emeritus of Civil Engineering at the University of Arizona. Dr. Ehsani says the pipe can be easily manufactured to any shape or size, will not corrode, and weighs about 10 percent less than traditional pipes.
“The walls of StifPipe® consist of a lightweight honeycomb core covered with carbon or glass Fiber Reinforced Polymer (FRP), a technique that has been successfully used in the aerospace and ship-building industries for decades.” Ehsani explained. He adds that “with many construction projects trying to achieve LEED certification, the use of StifPipe® can contribute significantly towards achieving such certification on pipeline projects.”
According to QuakeWrap, lightweight materials, a fast production rate, recyclable materials that are durable and environmentally safe, and the ability to build the pipe on-site are among the factors that contribute to the sustainability of the StifPipe®. Ehsani notes the pipes have already been used to repair deteriorated pipes and culverts in both the U.S. and Australia, saving significant costs over traditional repair methods.
In December 2012, the pipe sections were used to repair and rehabilitate a corroded corrugated metal pipe (CMP) culvert in Mobile, Ala. Last year, QuakeWrap used the pipe to repair the corrugated metal pipe culvert at Gillies Range Road, near Cairns, Australia.
