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.

Wedge type plug and method of plugging a lateral line

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.
