Abstract
A method for rehabilitating a pipeline with a liner includes providing a coupling member to connect a liner to a pipeline element. A first alignment element is connected to an end of the host pipe and a second alignment element to an end of the coupling member to axially align both components. A length of the liner is provided through the pipe and the coupling member to expose a joining section of the liner outside the pipe. The coupling member is brought towards the pipe such that the first and second alignment elements mate and the joining section of the liner is received in the coupling member. The joining section of the liner is pressurized to engage an interior surface of the coupling member, and a curable resin composition of the liner is cured to form a functional joint between the coupling member and the liner joining section.
