Abstract: The invention relates to a construction industry pipe for use in the construction industry, such as for example a drain pipe or a central vacuum cleaner pipe or the like, comprising a tubular body having a substantially non-collapsible outer wall comprising rigid sections alternating with corrugated flexible sections. The invention further relates to a method for manufacturing such a pipe, which involves the technique of blow/vacuum moulding, and a method for installing a conduit system comprising such a pipe.
Abstract: A flexible hose (1) with a corrugated wall (2), comprising an internal surface (3) with projections (4, 5) and recesses (6, 7), said hose (1) being obtained by moulding a plastic material, wherein each internal projection (4, 5) comprises a substantially flat and smooth top face (8, 9). Each top face (8, 9) has a first width (W1) and each internal recess has a second width (W2). The ratio between first width and second width (W1/W2) is preferably larger than or equal to 2.2. The hose may comprise a hollow longitudinal protuberance or score.
