Abstract
The invention relates to a coating system in the form of a vehicle (3), which can travel in a pipe (1) or a duct. The coating system is pulled over an appropriately stabilised section of piping (4) in such a way that the inner wall (58) can be evenly coated by a rotating distributor (18) with an outlet opening (29). The various product and supply lines (20, 21, 22, 136) are securely accommodated inside the section of piping (4) by means of a highly resistant flexible tube (138) into which they are drawn. Said flexible tube is air-tightly sealed by covers (148, 149) or a terminal block (150) at the ends and is also configured to absorb tensile forces. The individual supply and product lines (20, 21, 22, 136) are thereby protected in the section of piping (4) without being subjected to excessive pulling or other forces. They are also prevented from interfering with each other. The advantageous, simple, lightweight configuration of the section of piping (4) can therefore be used to continuously clean sections of pipes (1) and ducts of 150 m and more.
