<p>For achieving a branch connection to a pipe under pressure by means of a screwthreaded connector provided with a sealing device interposed between a radially projecting member on the connector and the pipe, there is produced a fluidtight enclosure having an aperture whose contour is connected in the fluidtight manner to the region of the pipe in which the branch connection is to be made. The sealing device is applied against the pipe before producing the enclosure so that the contour of the aperture of the enclosure is connected to the pipe through the applied sealing device. A hole is thereafter drilled in the pipe and tapped and the connector screwed in the tapped hole from inside the enclosure.</p> |
