Fremgangsmåde til demontering af en rörende fra en kobling og tilsvarende koblingsanordning

摘要

When the clamping ring (24) is unscrewed and retracted, a split dismantling ring (31) is placed on the tube (2) between the clamping ring and the end connector (4). On screwing up the clamping ring, the dismantling ring (31) lifts the teeth on the anchor ring (22) clear of the outer surface of the tube so that it can be withdrawn. The end piece consists of a body (4) in which is placed an anchor ring provided with teeth, which engage with the outer surface of the tube. The anchor ring is held in position by the clamping ring. A seal ring (18) and a back up ring (20) are provided in the recess (16) of the end connector. The dismantling ring is of a split format so it can be fitted onto the tube and has an angled front (36) for lifting the teeth of the anchor ring clear of the tube. An Independent claim is also included for the disconnecting system.
