The results of experiments indicate that the proposed method of restoration of the sucker rods the method provides growth of a limited fatigue limit of the samples according to theproposed method of restoration of the rods in 3-4 times . The insulating composite coating of the sucker rods performs not only the anti-corrosion protection function, but also mechanically strengthens the surface of the sucker rod . With the help of the developed method and the obtained research results, it is possible to predict the resource of the sucker rods in the range up to 25-35 million cycles and to substantiate the periodicity of their defectoscopy which should be carried out every 2 years in a well (it is desirable during underground repair), which will allow rational use of rods and significantly reduce accident rates during extracting oil from wells.
