AI Technical Summary
Existing monitoring technologies for high-sulfur gas pipelines cannot monitor key indicators such as corrosion rate, pipeline vibration, and foundation settlement in real time. Sensors are prone to corrosion and damage, data timeliness is poor, assessment methods ignore the combined damage of multiple factors, false alarm rate is high, and operation and maintenance rely on manual inspection, making it difficult to locate the cause of failure in a timely manner.
A sulfur-resistant encapsulated smart sensor array is used for multi-source data acquisition. The data is transmitted through dual-channel redundant communication and preprocessed and fused with multi-source data. The stress intensity factor is calculated using a multiaxial stress coupling factor model. The crack propagation rate is predicted by combining the sulfide stress cracking sensitivity coefficient. The residual strength is assessed by combining the vibration-settlement composite influence model. Finally, the pipeline risk is calculated using a multi-parameter risk model and a CFD model.
It enables real-time monitoring of multiple parameters in high-sulfur gas pipelines, improves equipment reliability, reduces false alarm rate, provides intelligent risk level classification and early warning capabilities, reduces reliance on operation and maintenance, and enhances the level of safe operation.
