We developed a technology, produced, and tested an ultrasonic installation aimed at treatment of the pipe threads with the help of radial ultrasonic vibrations and studied the microhardness of the outer surface of the thread profile. We also performed metallographic investigations. The pilot field tests of the branch pipes of tubing strings with strengthened threads were carried out and positive results were obtained.
