The greenest product is the one you don’t have to replace.
In 2008, after 33 years of exposure to seawater, a section of a Flowtite GRP pipe was brought ashore for analysis of its condition and mechanical properties. After cleaning parts of it, the pipe looked brand-new. It showed no visible signs of aging and its mechanical properties were basically unchanged.
To all concrete and steel pipe suppliers: We challenge you to show us something similarly impressive!
