Abstract

The method proposed for establishing a link between a main line carrying a fluid and a fluid-takeoff line is carried out by means of a pipe-broaching unit. The pipe broaching unit has, located in a drilling-bit guide pipe (1), a drilling-bit feed sleeve and, located in the feed sleeve, a drilling bit (7). Initially, the feed sleeve (6), together with the bit (7), is turned so that it penetrates down towards the main line (H) until the feed sleeve (7) contacts a bottom stop. The pointed sealing edge (65) of the bit now seals off the main line (H) from the fluid-takeoff line and the outside environment. The bit is now turned to penetrate further down, thus tapping the main line. When the bit is turned in the opposite direction, the feed sleeve remains initially in the sealing position, and is withdrawn together with the bit only when the bit moves back along the guide tube, thus leaving the bore free for fluid to flow through. Pipe-broaching units operating along these lines can also be used as valves.
