INFLUENCE OF SOIL POLLUTION ON GLASS REINFORCED PLASTIC WATER PIPES

摘要

The pipes of composite material such as GRP (glass reinforced plastic), can be found in operation in a wide range of highly corrosive environments, which results in the modification of material properties. The phenomena occurring in the mass of the composite are accelerating abrasion, hardness modifying, delamination, the separation matrix resin mass of glass fibre, etc. This article aims to clarify some aspects of the influence of soil pollution on the pipes GRP and experiments were performed on three samples of the pipe GRP DN150, PN10, SN10000 length approximately 150 cm were laid out in three blocks of experimental, at a depth of about 90 cm. After 24 months, the samples were subjected to composition analysis and structural dug in the laboratory.
