Drilling swivel DS model

The drilling swivel is an intermediate link between the trolley system and the rotating drilling tool. When drilling wells, the swivel provides free rotation of the drilling tool with simultaneous supply of drilling fluid to the drill string. High dynamic load capacity for this class of swivel ensures its reliability under the most difficult rotary drilling conditions. An enlarged through hole in the wellbore reduces hydraulic resistance when drilling fluid is pumped. The increased length of the swivel barrel allows cutting a new thread five times to replace the failed one, thereby increasing its service life.
