Abstract
PURPOSE:To eliminate the yield loss of an inner tube and to prevent the generation of buckling by specifying an outer diameter reducing percentage of the inner tube inserted into an outer blank tube of which one end is drawn and cold drawing worked through a die. CONSTITUTION:The corrosion resistant inner tube 2 having the specified outer diameter is inserted into the pointing worked outer tube 1, by extruding through the die 3 while the pointing part of the outer tube 1 is chucked by a drawing machine, a corrosion resistant duplex tube whose whole outer tube 1 and inner tube 2 are uniformly adhered is manufactured. At this time, as the diameter reducing of the outer tube 1 is performed, the outer diameter reducing percentage of the inner tube 1 is specified to regulate to a range of 0.5-5.0%. Therefore, even though the tube has a thin wall, buckling is not generated and the inner tube is integrally stuck to the outer tube.
