One-bed RFECT system for inspection of circumferential cracks in 16 inch gas pipeline

摘要

Inspection of unpiggable pipeline becomes one of major issues in the gas pipelines industry. Remote field eddy current testing (RFECT) has strong potential for inspecting unpiggable pipelines among the various NDE methods. Thus, in this study, design of RFECT system including driving coil, sensing coil and passive scanning module and intial experimental results obtained from fabricated one-bed testing system isdicussed.
