Abstract: To produce an integrated coupling on pipes manufactured according to the centrifugal casting process, insert rings made of soft PVC are placed into the end parts of the pipe shell mode. In the recess (5a) of one end part (4a), a coupling sleeve (7) is produced by wrapping on a laminate. A recess (5b) provided with an additional annular groove (5c) is produced by the insert ring in the other pipe end part (4b). A prestressed sealing ring (8) is placed into the groove (5c). Projecting beads (8a, 8b) of the sealing ring (8) are compressed by the coupling sleeve (7) on coupling the pipes. The material of the sealing ring (8) that is now being displaced finds space in annular flutes (8d) provided on the inner side of the sealing ring. This integrated coupling is suitable for nonpressurized pipelines and especially for pipes intended for lining reinforced concrete or concrete pipes.
