Abstract
A method for lining pipes in a pipeline. The method is characterized in that the air in the pipeline is sucked from an outlet by a vacuum pump together with plastics mist, and additional air is supplied from an inlet of the pipeline at a low pressure, so that the pipeline is lined with the plastics. The residual plastics mist is recovered into a tank at the outlet end of the pipeline.
