Helical corrugated conduit housing for Ric-wiL prefabricated insulated pipe units is now furnished by the Ric-wiL Co., 1572 Union Commerce Bldg., Cleveland, Ohio, with a reinforcing full welded lock seam extending spirally the entire length of each section. Automatic machine weld is made a t the factory before galvanizing, assuring a permanently pressure tight, waterproof structure. Sections are 21 feet long, completely fabricated with pipe or pipes a s specified, insulation and aligning pipe supports. Conduit ends are expanded smooth for a distance of 3 inches, removing corrugations to facilitate tight field connection of sections. The drive coupler is adaptable to mechanical or welded closure, with a minimum of field labor.
