Abstract:
A pressure container with an improved safety degree and life, comprising:a pressure-resistant body equipped with weep-holes and formed of a material subject to corrosion when contacted by a process liquid;an anti-corrosive lining made up of several elements welded to each other so as to line the inside of the pressure resistant body and define a chamber for containing the process fluid, and having a plurality of lining holes each corresponding to a weep hole forming outlets for a chamber defined by the lining;a plurality of first strips made of a corrosion-resistant material, pre-shaped to suitably lay on the surface of the lining near weldings of said elements and covering the weldings;a plurality of second strips of corrosion-resistant material each adjoining a first strip with an outlet such that all the outlets are covered;a plurality of strip welds joining the edges of said first and second strips onto the lining and adjoining strips,wherein each of said first and second strips are welded so as to form a hermetic channel with respect to the internal chamber and suitable for the flow of the process fluid, each channel being in communication with at least one of the outlets.
