165. gas pipeline
[Main Idea]
Present current method of monitoring flaw and gas leak, and then introduce new technologies.
[Structure]
P1: Current method for flaw and leak: magnetic field on the walls of the pipe + a sensor detects the leakage.
P2: EMAT technology for flaw: ultrasonic waves + an algorithm recognizes different patterns of the waves.
P3: MC technology for (tiny) leak: MC sensor detects the changes of the vibration frequency. MC+EMAT
