Glass Fibre Reinforced Pipes
Plastics have changed the world in which we live. We come across thermoplastics such as PVC, PE, PVDF etc. in almost everything we do. As toys, domestic equipment and in vehicles. This is why we often make the mistake of seeing these as the only type of “plastic”.
Glass fibre reinforced pipes are completely different. They belong to the family of thermoset plastics and are thermally stable. The mechanical properties are more like those of metallic materials rather than thermoplastic.
INCOMPARABLE MATERIAL
GLASS FIBRE REINFORCED PIPES IN COMPARISON
It is particularly interesting to compare materials that are applied under similar or identical conditions, namely steel or polyethylene. Though, of course each case has to be assessed individually, and though the one or other material has to be eliminated, it becomes obvious, that GRP wins off in nearly every "discipline". The relatively high investment costs are quickly compensated for by very low operating costs.
