Integrity assessment is a critical process in the oil and gas industry to prevent pipeline failures such as leaks or ruptures. This study evaluates a gas pipeline's integrity using two assessment methodologies: the conventional design code (ASME B31.8) and the defect-specific method (ASME B31G). An in-line inspection (ILI) conducted in June 2024 revealed the maximum corrosion depth with a depth-to-thickness ratio (d/t) of 0.35. The design code assessment classified the pipeline as potentially unsafe due to wall thickness falling below the minimum requirement. In contrast, the ASME B31G assessment showed the pipeline could safely withstand the design pressure. The comparison highlights the conservative nature of design codes and underscores the importance of defect-specific assessment in accurately determining residual life and optimizing maintenance strategies.
