    Abstract: Device with valve function which can be brought into and out of a pipeline and parked in the same. The device comprises a channel for throughflowing fluid, a valve (2) which is medium controlled and/or remote-controlled, a parking brake/packer seal unit (9) which with limited force can be brought to bear against the wall of the pipeline, a cylindrical wire anchor (1) with an external diameter which is slightly lesser than the internal diameter of the pipeline and can be brought into pressure contact with the pipeline.

    Abstract: A centering apparatus for use by the laying of heavy tubes of relatively large dimensions, especially for centering the spigot end of a tube relatively to the socket end of a positioned tube, and comprising a clamping device with at least two interconnectable members adapted to be attached to the socket end, and a guiding device for slidable guiding of the spigot end into the socket. The guiding device includes a number of brackets mounted to the interconnectable member enclosing the lower peripheral part of the socket end, which brackets project axially from said member and have guiding surfaces forming a chute onto which the tube to be laid down can be lowered to be pushed in centered position towards the adjacent tube end.
