  • Explosion-proof magnetic flux leakage inspection apparatus for well tubing
    Patent number: 9328607
    Abstract: Explosion-proof magnetic flux leakage inspection apparatus for well tubing includes a hermetically sealed interior chamber with an inner wall assembly that forms and surrounds a central channel in a manner that separates the central channel from the hermetically sealed interior chamber by the inner wall assembly. The central channel has an open top and an open bottom to accommodate passage of the well tubing through the central channel. An electromagnetic coil, magnetic flux leakage detector assembly, and a shallow reading detector assembly are positioned in the hermetically sealed interior chamber around the inner wall assembly.
