摘要： Tube-bundle equipment for heat exchange operations at high pressures and temperatures, under conditions of high aggressiveness of the process fluids, comprising a titanium lining (11) and a series of tubes (1) consisting of at least one layer of zirconium (2), positioned in contact with said fluids, wherein the tube plate on which said tubes are inserted comprises an outer layer (S) of zirconium or an alloy thereof and an underlying layer (5) of titanium welded to the lining of the equipment. Said equipment is particularly used as a heat exchanger, for example as a stripper, in the high-pressure cycle of urea syntheses processes.
