Abstract: Structured wall plastic pipe comprising a tubular plastic mandrel and at least one plastic sheet having a honeycomb cellular structure wound around the mandrel in such a way that its cells are arranged radially to the surface of the mandrel, and firmly attached to the latter, this pipe being characterized in that its cells are asymmetrical, i.e. have a cross section for which the envelope has a shape factor (defined as being the ratio of its largest dimension to its smallest dimension) greater than 1. Process for manufacturing such a pipe and its use for the discharge of wastewater or rainwater.
