Abstract: An apparatus, system, and method for tapping and reinforcing a valve of a liner lined host pipe with a fitting device assembly that includes a service sleeve having a flange, a cylindrical body, and an engaging end and a reinforcing sleeve having a flange, a cylindrical body, an engaging end having at least one annular ratchets configured to engage with the engaging end of the service sleeve in order to secure the service sleeve and the reinforcing sleeve together, and a plurality of cutouts in the cylindrical body. A cork assembly that includes the service sleeve and a cork having at least one radial appendage is inserted into the valve, then the host pipe is lined with a liner. The cork assembly is located, and the cork is removed from the cork assembly. The reinforcing sleeve is then installed into the service sleeve in the valve.

Abstract: A patch is provided and described that can be used with the installation of a cured-in-place structural liner in a conduit when the conduit has protrusions into the conduit. The patch is made with similar material to the liner, or felt, and is impregnated with epoxy. The patch may be shaped to more closely match the anticipated curve of the outer surface of the liner. Tools for the installation of the patches, a method of use, and tools for measuring the quality of the installation of the patch before the installation of the structural liner, are also described.

Abstract: The present invention relates generally to the field of structural pipe lining for conduit rehabilitation and more specifically, to methods for rehabilitating conduits using structural liners. There is provided a method for rehabilitating a tubular conduit having an inner conduit space and at least one service connection tied into the tubular conduit. A portion of the at least one service connection protrudes into the inner conduit space. A liner is provided for covering the inner surface of the tubular conduit. The liner is made of a flexible material capable of being impregnated with a first curable adhesive resin and has a film made of a material impermeable to liquid bonded onto the inner surface of the liner. Also provided, is a flexible sealing member made of a second curable adhesive resin.
