The present invention relates to an arrangement for use with a plug () for sealing against an inner wall of a pipeline (), comprising a main body and sealing means, which sealing means comprises an annular packer element (), arranged between two relative movable body elements () of the main body actuated by actuation means, where the movable elements form surfaces () in abutment against the packer element (). The packer element () comprises a radially inner section () which is mainly incompressible in a direction transverse to a circumferential direction and where sections of the two surfaces () in abutment against the inner section () of the packer element () in a retracted position, forms different angles in relation to an axis in radial direction in relation to a longitudinal axis of the plug.

Plug with expandable packer element

A pulling tool for use in the placing of equipment and acquisition of data from pipes and boreholes used in the production of oil and gas. For this purpose the tool is constructed round a central, elongate, cylindrical main element () to which there are arranged radially movable links (), () and () with chains () arranged thereto, running in grooves (). Radial movement of the links is provided by subjecting a terminal element () for the links () to an axial movement by means of an actuator (). The chains () are rotated by an electric motor () transferring, through the axle () connected to the bevel gears () and (), propulsive force to the chain wheel () on which the chains () are running.
