摘要: A bimetallic tube consisting of at least one tubular element in a first metal resistant to the corrosive and/or erosive action process fluid with which it is put contact, having end, or an area close externally coated layer second metal, different from and more suitable, respect this, for being seal-welded support. Tube bundle equipment be used thermal exchange operations high temperatures pressures, under conditions aggressiveness fluids, wherein comprises above characteristics. Said particularly as heat exchanger decomposer, example stripper, cycle urea synthesis processes where there are pressure, temperatures, consists
