FIELD: construction.
SUBSTANCE: lining material with tubular structure is impregnated with resin. The material is supplied to the top of the column by means of the upper roll. After that it is delivered downwards under the roll and through the resin layer in the column. The roll is located in the column basis. Finally, the material is supplied upwards to the upper calibration roll through the whole column, where material exits the column top. The impregnated in resin pipe is wrapped up with the outer coating, which is impermeable for resin, and sealed. The resin column height is enough to impregnate the material layer. The impregnated lining material is to be installed inside pipeline by stretching and inflation method or by material turning over. It is reasonable to solidify pipeline lining with steam if lining materials are formed with the internal impermeable layer.
EFFECT: wide range of facilities.
