We constructed a SQUID-NDI system for inspection of micro-flaws on heat exchanger copper tubes employing HTS-SQUID gradiometer and Helmholtz-coil-type inducer. The HTS-SQUID gradiometer was cooled using a coaxial pulse tube cryocooler. The detection of artificial flaws several tens of lm in depth on
