Abstract

The invention relates to a method for cleaning and coating pipe systems intended for carrying water, in which     a) water and compressed air are forced into the emptied pipe systems for coarse cleaning,     b) an acid which remains for some time in the pipe system is subsequently filled in under pressure,     c) the pipe systems cleaned in this way are dried by means of compressed air,     d) in order to coat the pipe systems a liquid plastic is filled in under pressure and     e) excess plastic material is let out.
