Inspection system for heat exchanger tubes |
摘要 |
A system for inspecting the relatively long, thin-walled, small-bore tubes of a heat exchanger provided with support plates for holding the tubes in predetermined positions, comprising a composite scanner having a plurality of flexure springs contacting the interior surface of a tube for detecting and profiling tube abnormalities as the scanner traverses the tube and an eddy current sensor for generating a unique signal as the scanner passes a contiguous support plate to assist in the accurate location of tube abnormalities.
