METHOD OF ASSEMBLING CONICAL THREADS OF CLUTCH AND PIPES

摘要

FIELD: joints or fittings for pipes. ^ SUBSTANCE: method comprises screwing the thread at one of the ends of the clutch on the pipe thread by means of a machine tool. The thread at the other end is screwed on the pipe thread by transmitting torque through both of the threaded joints. The second threaded joint is made so that the torque of unscrewing exceeds the torque required for of screwing the second threaded joint. ^ EFFECT: enhanced reliability. ^ 7 dwg
