A review on different pipeline defect detection techniques

This chapter attempts to outline the pipeline failures and their impact on safety and environmental risks besides causing blockages and leaks in pipe networks. Furthermore, non-destructive testing techniques for detecting leakage and blockage are studied. They are visual detection approach, fluid odorant approach, mass balance approach, real-time transient model-based approach, pressure deviation approach, supervisory control and data acquisition system based on leakage identification approaches, pipeline hydrotest approach, magnetic and ultrasonic pipe detection approaches, acoustic emission inspection and monitoring system, wave warning system, pulse-echo flaw detector approach and acoustic wave reflectometry. Eventually, the stationary wavelet transform method is presented for structural health monitoring.
