Flanges serve as indispensable connecting components in pipeline systems, widely applied across petrochemical, municipal water supply, power generation, and various industrial sectors. Flanged connections offer advantages including ease of disassembly, reliable sealing, and strong adaptability, making them the standard connection method between pipelines and valves, pumps, and various equipment. However, flange joint leakage incidents occur frequently in actual engineering operations. Statistics indicate that approximately 18% of all pipeline leakage accidents are caused by flange joint failures. Flange leaks not only represent lost productivity but also pose safety hazards and incur expensive repair costs. This article examines the most common issues in flange connections and provides analysis based on industry technical standards and expert recommendations, serving as a reference for engineering designers and field construction personnel.
