<p>Method for forming a bypass around a leakage site in a pipeline conveying water, crude oil or natural gas comprises inserting a T-piece having valves in all three flow paths in the flow direction before and after the leakage site. Preferred Features: A double T-piece with a barrier between the T-branches is inserted in a separating region. The branch assigned to the non-damaged pipe section interacts with the bypass line and the branch assigned to the defective pipe piece is parallel switched.</p> |
