ABSTRACT:
A method for lining pipes of a pipeline. The method is characterized in that at a first stage, mist of plastics having a low viscosity is passed through the pipeline by carrier air at a low pressure, and at a second stage mist of plastics having a high viscosity is carried through the pipeline at a high pressure, thereby to form double layers of plastics on the inner wall of the pipeline.
