Abstract

725,075. Tubular heat-exchange elements. MANNESMANN AKT.-GES. June 25, 1953 [July 9, 1952], No. 17702/53. Class 64 (3). In a tubular heat-exchange element in which an outer tube 1 is formed with indentations 1a to maintain it at a distance from an inner tube 2, the wall of the outer tube is thickened locally by adding welding material 3 at the base of the indentations.
