A detailed investigation has been carried out for analysing the failure of an isolation valve fitted to a LPG storage tank. The analysis carried-out included chemical composition, metallography, fractography and fracture toughness evaluation. This case study shows that the 'normal' defects which would pass through non-destructive examination, during quality control, could combine leading to catastrophic failure, during service.
