A method and system for locating a branch conduit opening into a main pipe following lining the main pipe with a liner includes moving a robot (2; 42) down the lined main pipe and scanning the liner using an infrared scanner mounted on the robot (2; 42) to acquire infrared data. A temperature drop outside the liner as compared to adjacent surfaces is sensed with the infrared scanner. The infrared data is compared with other location data regarding the branch conduit opening and a branch conduit opening location outside of the liner is determined based on the infrared data and the other location data. In another aspect, the infrared scanner is tuned to more particularly sense temperatures associated with the presence of a branch conduit opening.

Cured in place liner system and installation methods
A cured in place liner system and associated connections and methods are disclosed. The cured in place pipe system forms a completely rehabilitated, stand-alone, fluid-tight flow path between upstream and downstream portions of an existing pipe system. The rehabilitated flow path is stand-alone in that the liner system does not rely on structure of the portion of the pipe system through which the liner system is installed to define the fluid-tight flow path. The flow path between upstream and downstream portions of the liner system is defined by and made fluid-tight solely by components of the rehabilitation system such as cured in place liners and couplers. The portion of the pipe system through which the rehabilitation system is installed merely provides a path (e.g., through the ground) through which the cured in place liner system can be inserted. After the cured in place liner system is installed, the liner system forms a fluid-tight flow path between an upstream portion of the pipe system and a downstream portion of the pipe system. Various types of connections may be used. In addition, various types of methods may be used in forming the connections, such as using a mold to cure connecting sections of the cured in place liners in desired configurations (e.g., having a generally circular outer profile) for forming connections with the liners.

A cured in place liner system and associated connections and methods are disclosed. The cured in place pipe system forms a completely rehabilitated, stand-alone, fluid-tight flow path between upstream and downstream portions of an existing pipe system. The rehabilitated flow path is stand-alone in that the liner system does not rely on structure of the portion of the pipe system through which the liner system is installed to define the fluid-tight flow path. The flow path between upstream and downstream portions of the liner system is defined by and made fluid-tight solely by components of the rehabilitation system such as cured in place liners and couplers. The portion of the pipe system through which the rehabilitation system is installed merely provides a path (e.g., through the ground) through which the cured in place liner system can be inserted. After the cured in place liner system is installed, the liner system forms a fluid-tight flow path between an upstream portion of the pipe system and a downstream portion of the pipe system. Various types of connections may be used. In addition, various types of methods may be used in forming the connections, such as using a mold to cure connecting sections of the cured in place liners in desired configurations (e.g., having a generally circular outer profile) for forming connections with the liners.

Air inversion and steam cure of cured in place liners apparatus
An air inversion and steam cure apparatus for installing a flexible resin impregnated cured in place liner in an existing conduit is provided. The apparatus has a low friction seal between a moving liner and the stationary apparatus gland. The gland is operated and adjusted by displaceable members that move substantially perpendicular to the liner being inverted to engage the moving liner as it passes through the gland. No part of the gland extends into the chamber so that once a pre-shaped gland is adjusted, the pressure on the moving liner is not increased. As the liner reaches the distal end, it enters a sample and porting pipe with an exhaust pipe gland and exhaust pipe and is pierced by a rigid porting tool. Steam is then introduced into the liner to cure the resin and is exhausted through an exhaust hose connected to the porting tool. After cure, steam is replaced with air to cool the liner and the ends are cut to restore service through the existing conduit.

Method and apparatus for forming a grommet assembly to seal and reinforce holes through a cured in place liner for securing a cable. A first grommet base having a centrally located aperture with wedge shaped grooves is positioned on one side of the hole. A barrel having two opposed sets of wedge shaped projections is inserted into the grommet base and a second grommet base is placed on the barrel and pushed towards the liner until the second base firmly contacts the top surface of the liner and compresses the liner against the first base. The wedge shaped projections on the barrel and the complimentary grooves in the central apertures of the grommet bases prevent the barrel from being pulled out of either grommet base. The end of the barrel which projects out above the second base is cut off flush with the top surface. A hydraulic press to install the grommet assembly is also disclosed.

Reusable inversion sleeve assembly for inversion of cured in place liners
Installation of a flexible cured in place liner by inverting the liner utilizing an inversion sleeve assembly with an installation apparatus having at least one selectively operable rigid gland. The sleeve assembly includes a sleeve portion of an absorbable material secured in an apparatus with an inversion boot fitted at the distal end with an inlet port for inversion and/or curing fluid. The sleeve assembly and apparatus are particularly well suited for inverting with air and curing the liner with steam introduced through a perforated lay flat hose using an apparatus with two glands. The installation sleeve is the same dimension as the liner to be installed and is reusable thereby substantially reducing the set up time to install using the dual gland apparatus. Preferably, the flexible sleeve is a length of dry cured in place liner inverted on to itself to expose two impregnable surfaces. The sleeve may have a built in fluid inlet port for use with a dual gland apparatus.
