Environmental Compatibility of GRE Pipes in High-salty and CO2 Conditions

Glass Reinforced Epoxy (GRE) pipes (DN100) cured by aromatic amine were tested in the ageing environment containing salt of high concentration at different temperatures. By measuring the change of properties before and after ageing,iccluding hoop tensile fracture strength,Barcol hardness etc.,the effects of salt concentration and temperature on the mechanical properties of GRE pipes were studied. The results showed that factors such as temperature and salinity had little effect on the hoop tensile fracture strength and Barcol hardness of GRE.
