Method and apparatus for providing the inner surface of a pipe line with a lining

A method 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, said hose comprising a textile jacket provided with an inner lining, said inner lining containing a plurality of apertures,
• providing said flexible hose material having a porous structure inside the pipe line which has been lined with the tubular lining material and
• introducing pressurized steam into the interior of said flexible hose whereby said steam is introduced through the pores of said flexible hose along the inner surface of the lined pipe line, said flexible tubular lining material being warmed to accelerate the curing of the binder interposed between the inner surface of said pipe line and said flexible lining material.

• a flexible hose material having a porous structure, said hose comprising a textile jacket provided with an inner lining, said inner lining containing a plurality of apertures,
• said flexible hose material having a porous structure disposed inside said pipe line which has been lined with the tubular lining material and
• means for introducing a heated gaseous fluid stream comprising pressurized steam into the interior of said flexible hose whereby said steam 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 so as to accelerate the curing of the binder interposed between the inner surface of said pipe line and said flexible lining material.
