The intelligent flange condition monitoring system based on the Internet of Things has entered the testing phase.

The concept of "smart flange" integrating micro sensors and wireless transmission technology is moving towards practical application. The research team has embedded tiny strain and temperature sensors in the flange body, which can monitor changes in bolt pre-tightening force, pressure distribution on the sealing surface, and early characteristics of medium leakage in real time. The data is uploaded to the monitoring platform through low-power IoT technology to achieve predictive maintenance. This system is expected to revolutionize the traditional "regular maintenance" model of flanges, especially for unattended platforms, long-distance pipelines, and other critical infrastructure, enhancing safety and operational efficiency.
