ABSTRACT:
A method and apparatus are disclosed for blocking the flow of fluids through the interior of an elongated pipe section. The apparatus includes a pair of sectional housing members for interconnection around a flanged pipe joint to form an essentially airtight enclosure. Socket members are provided for selectively loosening and tightening bolts on the flanged pipe joint within the enclosure of the housing member, so that a cut-off blind member may be inserted between the pipe joint sections and then clamped in position to block the flow of fluids. Preferably, the assembly further includes a separate sealing ring mechanism which can be inserted between the pipe sections after the blind is removed, to serve as a replacement for the gasket material originally between the pipe sections.
