Method and apparatus for spot repair of pipe

An in situ pipe repair placement, transport and installation device comprising:

• a. a cylindrically shaped inflation component comprising fluid impermeable first and second end pieces each having a fixed diameter and wherein at least one end piece has an access port, a cylinder component that is fluid impermeable and comprising an elastomer and further comprising a first end and second end that are fluid sealably attachable to the first end piece and the second end piece and wherein the combined cylinder component, first end piece and second end piece form an inflatable annulus;
• b. a cylindrical shaped heating component with an expandable diameter comprising a knit of carbon fiber or carbon hybrid fiber and further comprising a first end and a second end and dimensioned to fit proximate to a surface of the cylinder component;
• c. a first and second conductive end component attachable to each end of the heating component and connectible to an electric power source;
• and
• d. a first and second cone attachable to the first and second end pieces and comprising at least one aperture for an electrical cable and a fluid hose and wherein a base diameter of each cone is at least as large as the diameter of the first and second end pieces.

An interior surface pipe repair device comprising:

• a. an electrically resistive heatable bladder having an inflatable annulus and comprising an elastomeric layer, a heating component, and cone ends wherein the cone ends and bladder are dimensioned to fit within a pipe interior, and a middle segment of the bladder between the cone ends;
• b. fluid conveying components connectable to the inflatable annulus;
• and
• c. electrical power connector components connectable to heating component and a power source.

An interior surface pipe repair material placement, transport and installation method of insitu pipe repair comprising:

• a. placing a repair material containing heat responsive resin onto a middle segment of an electrically heatable and fluid inflatable device, the middle segment being between a first cone end and a second cone end wherein a diameter of the middle segment is less than a base diameter of the cone ends when the device is deflated and greater than the base diameter when the device is inflated;
• b. attaching a fluid conveying component to an inflatable annulus of the device;
• c. attaching an electrical power component to a resistive heating component of the device;
• d. inserting the device and repair material into an interior of the pipe to be repaired;
• e. maneuvering the device within the pipe to a repair location;
• f. inflating the annulus of the device sufficiently to press the repair material to the interior surface of the pipe;
• g. energizing the resistive heating component sufficiently to heat the heat responsive resin of the repair material;
• h. de-energizing the resistive heating component after the repair material has been sufficiently heated;
• i. deflating the bladder;
• and
• j. removing the device from the pipe.
