ABSTRACT:
A method and system for separating and sealing sections of a pipeline are disclosed. A spherical member is advanced by pressure along the interior of a pipeline to seat against a restraining member forming a pressure-tight seal. The advancing pressure may then be increased within the pipeline to monitor for leaks in the upstream section of the pipeline.
