With the growing gas industry, gas pipelines have been developed rapidly in terms of safety, economy, efficient and on time delivery. Most of the gas pipeline have seen their design life and its reliability is at risk due to metal degradation. Such degradation can occur for few reasons, for instance stress corrosion cracking (SCC). SCC normally initiates on the external surface and grows in both depth and surface directions on gas pipeline. Stress Corrosion Cracking is time-dependent phenomena where crack growth depends on few factors like stress, environment, process, stress intensity, strain rate, temperature, or materials of constriction. SCC can occur when certain conditions are reached. These conditions could be electrochemical, mechanical or metallurgical, that must exist to initiate the crack. It’s very hard to detect SCC in the first place.
