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 of the bladder has an eccentric taper so that one side is substantially collinear with a middle section of the bladder. A conduit for exhausting steam from the bladder is positioned near the collinear side of the end section.
