FIELD: mechanical engineering. SUBSTANCE: method involves fitting of pipes onto a sealing cylindrical bush with a ring flange, mounting of a compressible clutch on the outer side of the pipe, the clutch has an annular groove on the outer side with the cross section in the form of a trapezoid; reducing of the pipe and the clutch from one clutch end to the other. The reducing force is directed at an angle 70-84° to the outer surface of the clutch. EFFECT: improved reliability. 2 cl, 5 dwg
