Beyond numbers: an exploratory data analysis of gas pipelines’ service life

This study presents an exploratory statistical analysis of 1616 corrosion-induced incidents in US gas transmission pipelines, using data from the Pipeline and Hazardous Materials Safety Administration between 1970 and 2023. The analysis identifies patterns and trends in corrosion-related failures, emphasising the main factors influencing pipeline degradation, the effectiveness of mitigation strategies, and the risks inherent in current operations. Results indicate an average service life of around 38 years for corrosion-affected pipelines, with external corrosion and localised pitting as the most prevalent mechanisms. Significant regional variations are linked to pipeline density and climatic conditions. The findings highlight the importance of material selection, climate adaptation, and advanced corrosion prevention techniques in extending pipeline integrity and service life. The study underscores the need to prioritise high-risk regions and aging infrastructure for targeted maintenance and investment. By providing quantitative insights into the temporal and spatial dimensions of corrosion failures, the research supports data-driven strategies to enhance pipeline safety, reliability, and cost efficiency. This study also proposes policy guidance, encouraging for updated integrity management programs, incentives for corrosion-resistant materials, and research into innovative prevention technologies to ensure long-term resilience and public safety.
