摘要： The invention comprises a fluid inflatable bladder with at least one electrical heating component comprised of carbon fibers. Also subject of the invention is an interior surface pipe repair material placement, transport and installation device for in situ pipe repair comprising an cylindrically shaped electrically resistive heatable bladder having an inflatable annulus with fixed diameter cone ends wherein the cone ends and the deflated bladder are dimensioned to fit within an interior of a pipe. The tapered cone ends facilitates maneuvering of the bladder within the pipe, and a middle segment of the bladder may be inflated to expand in a radial direction to press a repair material to the interior pipe surface. The invention includes fluid conveying components connectable to the inflatable annulus; and electrical power connector components connectable to resistive heating elements of the bladder.
