发明名称 PIPE CONNECTION PARTICULARLY ON COMPOSITE PIPES
摘要 The invention relates to a pipe connection, particularly for composite pipes (2), with a supporting sleeve (4) with at least one connection region (3) and an assigned pressure sleeve (6), the supporting sleeve (4) being provided with a shoulder (10) and with main, ring-shaped beads (12), the pressure sleeve (6) embracing the pipe end that is on the connection region (3), the pressure sleeve (6) in each case being constructed as a plastically deformable pressure element and this, in the final state pipe connection (1), brings about with ring-shaped, inwardly directed depressionregions (11, 11', 11") a sealing immobilization of an associated pipe end. In order to provide a permanently tight connection, the connection region (3) of the supporting sleeve (4) is constructed as a working, support surface, which has aninner supporting part (14) adjoining the shoulder (10), an outer supporting part (15) adjacent to the end of the connection region (3) and an intermediate part (16) of smaller diameter with ring-shaped beads (12, 13), main ring-shaped beads (12, 12'). Between these and the inner and outer supporting parts (14, 15), additional ring-shaped beads (13) are provided in the central region of the intermediate part (16). The additional ring-shaped beads (13) are formed in each case by two partial ring-shaped beads, which form between themselves the boundary of an accommodating groove for an elastomeric ring-shaped body (19, 19').
