Electro Magnetic Defectoscope - China

price: contact company for price

Product Description:

Electro-magnetic Defectoscope locates string configuration and position of tools in the borehole exactly, and determines ferromagnetic material outside the casing, (e.g casing centralizer, surface casing etc.). Electromagnetic defectoscope is a through-tubing tool, it can be used to inspect tubing and casing, which saves operating cost and time to run-in and pull-out tubing string when detecting the casing string. Electromagnetic defectoscope can also be used to inspect two-layered casing strings.

Operation principle :

The physical fundamental of the Electromagnetic Defectoscope is Faraday’s induction principle. When supply current into the transmitting coil, there will be time-varying induced EMF in the receiving coil. If there is thickness variation or defaults in the pipe string, the induced EMF shall alternate timely. After data processing, one can diagnose fissure and openings in the pipe string and measure the pipe string thickness variation.
