Abstract
A method for securing a branch assembly to a pipeline includes positioning a first containment ring surrounding an area from which the branch is to extend, positioning a first annular seal within the containment ring to provide a first ring/seal arrangement, positioning a second containment ring spaced from the first containment ring and first annular seal, positioning a second annular seal within the second containment ring to provide a second ring/seal arrangement, positioning the second part of the branch assembly onto the seals, and positioning a first part of the assembly on the pipe line and securing the first and second parts together so as to leave an annular gap between the first and second ring/seal arrangements and to provide an access point or vent in the second part communicating with the annular gap.
