ABSTRACT:
A method and apparatus for causing a flexible tubular lining material to be fixed to the inner surface of a pipe line wherein the tubular lining material is initially attached to the inner surface of the pipe line by a binder provided on the surface of the tubular lining material which comprises providing a flexible hose material having a porous structure inside the pipe line which has been lined with the tubular lining material and introducing a heated gaseous fluid stream into the interior of the flexible hose whereby the heated gaseous fluid stream is introduced through the pores of the flexible hose along the inner surface of the lined pipe line, the flexible tubular lining material being warmed to accelerate the curing of the binder interposed between the inner surface of the pipe line and the flexible lining material.
