Abstract

13,153. Weidmann, C. June 2, 1913, [Convention date]. Metal pipes and tubes. - Corrugated heating- pipes are made with a smooth surface at the top and bottom by corrugating a sheet-metal strip on opposite sides of a smooth central portion c, then bending the strip into pipe form, and finally welding together the free edges d, which are left smooth.
