FLUOROCARBON REPAIR BLADDER

摘要

An inflatable bladder for repairing a failure in an underground pipe with a thermally reactive material is made of fluorocarbon rubber. At least one end section (14, 16) of the bladder has an eccentric taper so that one side is substantially collinear with a middle section (12) of the bladder. A conduit for exhausting steam from the bladder is positioned near the collinear side of the end section.
