An in-house hydrostatic burst testing system and an instrumented impact tester were used for the testing. Pipe specimens of 150 mm internal diameter, 6 mm thickness and 1000 mm long were used for burst tests where as, for impact tests pipe sections of 160 mm length were used. Pipes were exposed to selected environments ranging from outdoor exposures (upto 12 months) to accelerated exposures of dry heat, humidity, seawater, and salt fog for periods ranging from 100 to 1000 hours. Pressure performance of the GFRP pipes reduces to almost 80 % for high energies impact. The energy absorbing capability of GFRV pipes exposed to dry heat first increases and decreases thereafter, due to curing effect. For salt spray exposure conditions decrease in impact resistance was observed. A similar trend of decrease in impact resistance was observed for humidity ambient. For humidity 100% exposure, an increase in impact resistance was noticed.
