Investigate of implications of atmospheric corrosion on various flanged configurations for pipelines and process equipment

Atmospheric corrosion, commonly known as weathering is among the leading causes of infrastructure degradation. The extent of atmospheric corrosion becomes more concerning when it triggers localized and non-linear metal loss rates. One such scenario is the localized corrosion at the flanged connections in piping, pipeline, and equipment for hydrocarbon industry and even utility sectors. As reported by transportation board Canada, flanges degradation is among the leading causes of leaks/ spills from pipeline. Today, almost every protection measure for flanges namely Cathodic protection, protective coatings, reactive repairs, etc. have inherent limitations which limit the options for end users towards achieving adequate flange integrity. This study will help improve the understanding about various flange protection measures via quantified and systemic corrosion characterization along with validating a Canadian invention i.e., novel Flange Belt (Patent no. CA 3115319) for flange protection suitability.
