Abstract
A conduit, especially for sewerage, consists of a plastic, preferably polyvinyl chloride or polyethylene. It is intended reliably to improve the noise protection requirements. To this end, it is proposed that the conduit consist of an inner tube (6) and an outer jacket (8) surrounding the inner tube, and that the density of the outer jacket (8) be greater than the density of the inner tube. The single drawing belongs thereto. <IMAGE>
