FIELD: joints of fittings for pipes.
SUBSTANCE: conical pipe threaded joint comprises female member provided with inner conical thread, male member provided with outer conical thread, and indicator of screwing control made of a ring grove. The groove is formed by side walls that are made of intersections of the groove boundaries with the screw hollow of the thread, and the diameter of the groove bottom is less than the diameter of the surface forming the cone of the thread hollow in the plane nearest to the thread of the groove boundary. The surface diameter exceeds the inner diameter of the thread on the female member in the dangerous cross-section.
EFFECT: enhanced reliability.
