Abstract
An inflation anchor for sealing a conduit bore. A tubular elastomeric bladder is attached to a shoe assembly, with two layers of calendered steel cable being fixed to the shoe assembly and surrounding the bladder. At the free end of the bladder, an elastomeric cup is bonded thereto and overlaps the layers of cable. In operation, a valve is closed between the interior and exterior of the anchor, and fluid pressure increased in the conduit. The initial seal is made by the trailing cup edge expanding to firmly contact the conduit wall, after which the remainder of the cup expands into contact with the wall, and the tubular bladder subsequently expands as pressure is further increased, pressing the cable into frictional engagement with the conduit wall.
