摘要

Method of manufacturing a duct for use in a treatment plant ultra su00c8nico, and duct for use in a treatment plant ultra su00c8nico. A duct (10) for use in a plant with ultrasonic treatment is made of a steel pipe cylinder (12) by deposition in the inner diameter of a layer of corrosion-resistant metal (14).This is done preferably by grinding of the internal diameter to ensure that it is circular, the deposit on the internal diameter of the tube (12) of a metal resistant to corrosion, and again honing of the internal diameter of the tube, so as to ensure that it is circular and to reduce the espe Ssura of metal resistant to corrosion.And the coupling of ultrasonic transducers (16) to the exterior of the tube (12). Where the flanges (22) are fixed at the ends of the tube (12), these are fitted over each end of the tube so that the ends are capped so close, and are welded on the outside of the tube (12).
