Abstract

PURPOSE:To manufacture a long sized thick tube by a expanding without causing a buckling by moving the narrow width heating zone of the same coaxial shape as the metallic tube to be expanded at the fixed relative interval always to a plug. CONSTITUTION:A expanding by drawing is performed with moving a heating zone 5 in the same direction as of a plug 3 simultaneously with the plug 3 as well as moving the plug 3 by a drawing rod 4 with fixing one end of a metallic tube 1. The part of narrow width only is locally heated at the position where the metallic tube 1 which is about to be expanded with the advance of the plug 3 to the metallic tube 1 and the plug 3 are started to be placed into contact. Other parts are made to remain cold as they are, so that there is no reduction in a rigid body and the length of the limit for buckling generation is elongated and the expanding of a long sized tube is enabled.
