Abstract
Improved tubular element for heat exchangers, essentially characterized in that it consists of an inner metallic tube whose external surface presents a series of homogeneous roughnesses for the intimate connection of a surrounding tube of different material than the inner tube; said envelope body has on its outer surface a helical groove for positioning and subsequent fixing by its base a band that forms helical fins.
