Abstract
The invention relates to a pipe connection, particularly for composite pipes (2), with a supporting sleeve (4) with at least 6no 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 depression regions (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 an inner 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 main ring-shaped beads (12, 12'). Between the inner and outer supporting parts (14, 15), additional ring-shaped beads (13) are provided in the central region of the intermediate part (16…
