FIELD: mechanical engineering. SUBSTANCE: method consists in at least partially placing the edge of first member in hole of second member and bending it by edge of this hole at plastic deformation effected by means of pressure building devices. Above-mentioned edge of first member is pressed to curvilinear mated surface of pressing body placed in second plastic member near its hole and pressed out over surface of its conjugation with adjacent surface of pressing body radially in outer direction by edge of second member. Edges of both members are pressed to each other by applying pressure to opposite sides of edges, with sealing ring placed between them. EFFECT: enhanced tightness of connection of pipes. 18 cl, 9 dwg
