Abstract: Apparatus for inserting a generally U-shaped liner into a pipe and reforming the U-shaped liner into a generally cylindrical cross-section to line the pipe includes winches for pulling the U-shaped liner through the pipe, pigs for cleaning the pipe, manifolds to connection at opposite ends of the pipe and wedge-shaped expansion members for initially mechanically reforming the ends of the liner projecting from the pipe. The wedge-shaped members include bores for communicating fluid at elevated temperature and pressure within the liner for setting the liner in generally cylindrical configuration against the pipe wall. A flaring tool is used to flare the opposite ends of the liner.
