Abstract：Based on the principle of reverse magnetostriction effect and electromagnetic induction, four sensors were developed to examine the structure of an oil casing. An electromagnetic test was carried out for the oil casing under three-point bending load by this instrument. The changes of the electromagnetic signals and the stresses are very highly consistent. The results show that the method of detecting the stresses of oil casing pipes based on the electromagnetic induction principle is effective and feasible.
