Abstract

821,046. Making ribbed pipes for heatexchangers; jointing. VITS ELEKTRO G.m.b.H., and VITS, H. Oct. 11, 1955 [Oct. 13, 1954], No. 28884/55. Classes 83 (2) and 83 (4). [Also in Group XIII] A method of making a helically-ribbed pipe for heat-exchangers consists in rolling a red-hot iron band 2 of knife-shaped or triangular crosssection into a helix and applying the formed band to a pipe 1 of oval or elliptical crosssection and allowing the band to shrink thereon.
