An in-service stress corrosion cracking failure occurred in the 1300 kilometre long 864mm diameter Moomba to Sydney high pressure natural gas transmission pipeline in July 1982, approximately 5½ years after the pipeline was put into commercial operation.

A comprehensive field investigation of the failure was carried out in conjunction with a program of laboratory testing. The results of the investigation were used in the determination of the cause of failure, the probability of another failure occurring in the near future, an appropriate repair or replacement program, the appropriate operating conditions to minimise the risk of future failures and to evaluate some of the available monitoring techniques.
