Corrosion failures of flanged gasketed joints: A review

Abstract

Corrosion-induced leakage in flanged gasketed joints is a critical issue in various industries, with implications for safety, environmental compliance, and economic sustainability. This review paper examines the mechanisms and factors contributing to corrosion-related failures in these joints, clarifying the diverse range of materials, operating conditions, and gasket types that influence their susceptibility to degradation. The paper investigates the key corrosion processes, such as pitting, crevice, and galvanic corrosion, that can initiate and propagate in the joint's critical areas. It explores the role of environmental factors, including microorganisms, temperature, flow, and chlorination, in accelerating the corrosion process. Additionally, the influence of gasket materials and design on corrosion susceptibility is investigated, highlighting the importance of selecting appropriate materials and sealing technologies. Furthermore, it reviews various corrosion monitoring techniques that can help identify corrosion early, ensuring the integrity and reliability of flanged gasketed joints.
