The leakage detection of the steam pipeline is not only related to the insulation and effective transmission of steam, but also to the safety of the surrounding areas of the steam pipeline. The leakage detection of the steam pipeline is a regular inspection item. The existing detection method generally detects the important pipe sections by applying soapy water. The location of the leakage is detected by applying soapy water on the pipe section and observing whether the soapy water has bubbles.
