Abstract: A method and apparatus for moving pipe rehabilitation objects, such as a pipe liner through a host pipeline. Flexible tubing is used to connect to the pipe rehabilitation object and to apply a force to cause the pipe rehabilitation objection to move through host pipeline. The flexible tubing is also capable of conveying a fluid, such as a lubricant through the tubing.

Abstract: A welded connection kit for joining first and second lined pipes together includes a coupling sleeve to connect the first and second pipes together. The coupling sleeve has a thermal break in it. The coupling sleeve includes a first coupling member that attaches to the first pipe and a second coupling member that attaches to the second pipe. The first and second coupling members attach to each other to connect the first and second pipes. A first liner lines the first pipe and includes a first flange. A second liner lines the second pipe and includes a second flange. The first and second coupling members compress the first and second flanges together to form a fluid seal.

Abstract: A connection of two pipes each including a liner. Liner sections connected to the liners are sections joined together forming a joint of the liner sections. An electrofusion coupling may overlie the joint of the liner sections and be used to fuse the joint. A collar may be positioned to overlie the joint of the liner sections. A bushing may be positioned between the joint of the liner sections and the collar. Hubs may be connected to the ends of the pipes. The liner sections and hubs may include corresponding structure which resists movement of the liner sections away from the joint of the liner sections. A connection of two pipes each including a liner may be formed according to disclosed methods.

Abstract: A welded joint of a lined pipeline has a main pipe and an extension piece having a generally tubular shape, an inner wall and an annular weld connecting the extension piece to the main pipe. A liner extends through the main pipe and partially into the extension piece. A compression ring includes a flange and a compression portion. The compression portion engages the liner internally and compresses the liner radially outwardly against the extension piece so that the liner is sealed with the compression ring.
