This paper analyses current methods of non-destructive testing (NDT) for evaluating the technical condition of oil and gas equipment, focusing on strain gauge and ultrasonic techniques. Their advantages and limitations under complex geological conditions are reviewed. Improvements are proposed via temperature compensation in strain gauges and new piezoelectric transducer designs. The influence of thermal variations on transducer frequency characteristics is studied, and methods are proposed to stabilize acoustic coupling. Resonant frequencies of novel piezo plates and their ability to detect metal anisotropy are determined. A newly developed thickness gauge enables continuous monitoring of pipe walls, including oval cross-sections, which is essential for long-distance gas pipelines.
