Abstract

1,028,000. Making heat exchanger tubes. BROWN FINTUBE CO. Feb. 8, 1965 [March 4, 1964], No. 5426/65. Heading B3A. [Also in Division F4] In a method of providing a helically twisted strip in a heat exchange tube 10, a flat metal strip 11 slightly wider than the tube internal diameter is twisted helically by rotating a clamp 23 to form an element having an overall diameter which allows it to be inserted into the tube, the element diameter then being increased so that the strip edges abut the tube wall. The increase may be effected either by releasing a resilient strip held previously under tension; or by slightly untwisting a strip where this is made of a relatively non-resilient material. A hydraulic jack 32 may apply tension to the strip during the twisting operation. The assembly is finally placed in a furnace to braze the strip edges to the tube wall, the strip edges having been coated with copper or with silver solder as appropriate to the tube and strip materials used.
