Method for the safety and extension of the operating life of pressure equipment comprising an internal chamber suitable for containing a process fluid, surrounded by a pressure-resistant body (1) equipped with weep-holes (2), consisting of a material subject to corrosion by contact with said process fluid during operation, coated inside with an anticorrosive lining (4) made up of several elements welded to each other, wherein said lining weldings (3) are completely isolated from contact with the process fluid of the normal operating run, by a coating with adjoining strips (or plates) (10, 10', 10", 10"'), of the same material as said lining (4) or other corrosion-resistant material weldable thereto, which are subsequently seal-welded on the edges to said lining (4) and to each other, characterized in that the arrangement and welding of the edges of these strips (10, 10', 10", 10"') are such as to create a network of underlying interstices (or meati) (9, 11), communicating with each other and with at least one weep-hole (2).
