Pipe connection, particularly on composite pipes

A pipe connection for composite pipes comprising:

• a) a supporting sleeve extending in an axial direction and including:
• i ) a shoulder,
• ii) at least one connection region each connection region including:
• A) an outer end,
• B) an external, at least essentially cylindrical working, support surface, which is defined by an inner supporting part adjoining the shoulder, an outer supporting part adjacent to the outer end of the connection region, and an intermediate part between said inner and outer supporting parts, said intermediate part having an intermediate part diameter,
• C) main ring-shaped beads in said intermediate part, said main ring-shaped beads being separated from one, another to form an annular channel therebetween, said main ring-shaped beads having a diameter greater than said intermediate part diameter,
• D) additional ring-shaped beads axially separated from one another in said intermediate part and having a diameter greater than said intermediate part diameter, the axially separated additional ring-shaped beads forming an accommodating groove therebetween, said additional ring-shaped beads being axially spaced from said main ring-shaped beads,
• E) an elastomeric ring-shaped body positioned in said accommodating groove,
• b) a plastically deformable pressure sleeve assigned to each connection region, the pressure sleeve, in a position adjacent to the shoulder, embracing an end of a pipe that is positioned on the connection region, the pressure sleeve, in a state before deformation, being constructed as a cylindrical body of constant diameter, and in a final state of the pipe connection, including ring-shaped, inwardly directed depression regions, which are axially offset, and which sealingly immobilize the pipe end by providing an undulating deformation of a wall of the pipe between the supporting sleeve and the pressure sleeve, with at least one depression region of the compression sleeve being assigned to said annular channel and at least one other depression region of the compression sleeve overlying said intermediate part at a location spaced from said annular channel, whereby said pipe is captured and sealingly immobilized between said deformed pressure sleeve, and said connection region.
