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.

Cured in place liner system and installation methods

Method of lining a pipe

A plug for temporarily plugging a lateral line from lateral opening in a main pipeline. A distal end of the plug is inserted in the lateral line from the main pipeline. The plug includes a fitting tube and a wedge constructed for deforming a deformable portion of the fitting tube outward to plug the lateral opening. Axial movement of the wedge with respect to the fitting tube toward a flow area of the main pipeline causes deformation of the deformable portion. A gripping member may be positioned on an outer surface of the fitting tube. The plug may include a fitting on the fitting tube to facilitate gripping of the plug by a tool. A cutting and brushing assembly may be used to remove the plug from the lateral line. Methods of installing and removing lateral plugs are also disclosed.

A process and apparatus for internally reinstating a connection in a lined conduit is provided. The connection may be a branch pipe or corporation stop that may or may not protrude into the conduit. It may be milled prior to lining. The process includes the step of locating the connection visually or with a probe, such as all eddy current probe. forming at an opening in the lining at the connection and then installing a T-nut with a sealing gasket facing the liner to hold the liner in place and form a seal between the T-nut and liner and the connection. The apparatus includes a motor coupled to a turntable with drive to install the T-nut and a supply of T-nuts mounted on a slide for loading the T-nuts onto the drive for installation of the T-nuts without having to remove the assembly between each installation.
