The construction and subsequent operation of oil and gas wells is not complete without oil-well tubing. Tough requirements are imposed on threaded joints of oil-well tubing: ensuring the required level of wear resistance during multiple make-up-breakout cycles while maintaining the tightness of the joint. In this work, it is proposed to apply a coating formed by thermal diffusion galvanizing with the application of an additional surface layer of fluoropolymer by cladding with a flexible tool as a dry solid lubricating coating. The resulting coating is non-uniform in thickness (range from 21 to 31 microns). On average, the thickness of the coating on the couplings is significant - from 46 to 61 microns. The main thickness is due to the thermal diffusion coating, the thickness of the polymer layer does not exceed 7 microns. The anti-seize properties of a dry solid lubricating coating have been evaluated. The properties were assessed using a CKR-500 clutch wrapping machine. During the tests, the running-in of the coating was observed: peeling of the coating; the formation of stripes of a dark color with a mirror shine on the tubing couplings; partial transfer of the coating to the nipple end in the form of dark stripes (metal-to-metal seal); partial destruction and transfer of the coating to the places of maximum contacts, which leads to an additional increase in the antiwear properties of the threaded joint (the effect of “self-lubrication”). A significant increase in make-up moments was also observed: the torque was higher than 8000 N·m (instead of the planned 3700 N·m). The heating of the tight threaded joint was recorded (at 4-6 cycles up to 75 °C). The couplings successfully withstood 11 make-up-breakout cycles, after which no significant wear of the coating and the development of microdamages in the multilayer coating was observed. Thus, it is necessary to continue the work on the study of the properties of the coating of the type “thermal diffusion galvanizing + cladding with a flexible tool”.
