At this time, the question increase the reliability and durability of natural gas equipment acquired special urgency. The column of pump rods (KNSh) is one of the weakest links of rod well pumping units (SHSNU). It is the pump rods that sharply limit their reliability and durability. This is due to the extremely difficult operating conditions of the pump rods. Variable tensile and bending loads, the influence of corrosive environment, friction on the column of tubing, especially in inclined wells, deposition of asphalt-resin-paraffin substances and other operational factors lead to the appearance and intensive development of corrosion-fatigue cracks and, as , to the destruction of the column of rods. Such accidents involve high material costs for repairing and restoring wells. About 70% of oil wells in Ukraine operated downhole rod pumping units (SHSNU). One of the main problems associated with the operation of wells equipped SHSNU is frequent failure of the rod (NSH). The analysis of existing methods of repair rod will enable identify effective method of repair. A combined method of sucker rod repair by treatment with metal brushes and application of a modified polyurethane coating is proposed. Experiments of sections of full-length rods show that metal brushes are an effective means of cleaning and strengthening the rods, especially those that have already been in operation. It is established that the method of combined hardening by brushing and polyurethane coating further increases the value of the G-criterion by 20%. The modified polyurethane coating will increase the abrasion resistance of the rod when it contacts against the column of tubing on one side and prevent the deposition of asphalt-resin-paraffin substances on the body of the rods on other side
