... ABSTRACT A metallurgical investigation of multiple, externally-initiated, in-service leaks on an above-ground, mineral wool insulated, oil emulsion pipeline concluded that the likely crack-initiating mechanism was stress corrosion cracking (SCC). However, the leaks occurred on an above-ground...
