THREE INCREDIBLE “DID YOU KNOW” FACTS THAT WILL ASTONISH YOU ABOUT GRP PIPES
GRP pipes have an estimated lifespan of 150 years. In northern Norway, a GRP diffuser was installed as part of a subaqueous marine outfall in 1975. In 2008, it was brought ashore and the pipe looked almost brand-new and its mechanical properties were also basically unchanged!
LONGEST STRAIN CORROSION TEST:
The longest, still ongoing test was set up on October 4, 1978. The sample has now been exposed to the acid test for more than 40 years at 0.91 % strain, exposing it to a 5% concentration of sulphuric acid. The typical long-term operating strain of a GRP pipe in sewerage applications is merely 0.27 %.
This means that, in real-life applications, it reached an excellent safety margin of 3.4, implying that the pipes could serve several future generations.
ADDITIONAL 5% GRP COST SAVINGS:
Through the application of our EFFECTIVE FILAMENT WINDING method, and controlling the resin temperature ON-LINE, our client’s raw-materials consumption on GRP pipe production was optimized and reduced by 5%, also increasing the pipe technical characteristics.
