Method for rehabilitating a pipeline with a liner

A method for rehabilitating a pipeline with a liner of reinforcing fibers and a curable resin composition, the method comprising:

• providing a coupling member configured to connect a liner to other pipeline elements and comprising reinforcing fibers and a curable resin composition that is substantially fully cured in a first part of the coupling member;
• providing an alignment device comprising a first and a second alignment element;
• connecting the first alignment element to an end of a host pipe and the second alignment element to the coupling member to axially align the host pipe and the coupling member by providing mating surfaces when the coupling member is provided against the host pipe end;
• bringing the coupling member towards the host pipe such that the second alignment element provided on the coupling member is provided against the first alignment element provided on the host pipe;
• attaching the coupling member to the host pipe end by using the alignment elements;
• providing a length of the liner through the host pipe;
• providing a length of the liner through the coupling member;
• exposing the curable resin composition of the liner in a joining section of the liner;
• pressurizing a joining section of the liner that is received in the coupling member to bring it against an interior surface of a second part of the coupling member;
• and
• curing the curable resin composition of the liner to form a functional joint between the coupling member second part and the liner joining section.
