Beschreibung
Zusammenfassung:	An object of the present invention is to enhance efficiency of production of a heat-exchanger tube for a steam generator for use in a nuclear power plant. The producing method of heat-exchanger tube for a steam generator for use in a nuclear power plant includes an annealing step of annealing a tube 1, a grinding step of grinding an outer surface of the tube 1, and a heat treatment step of applying heat treatment to the tube 1 under an environment of an oxidation inhibition atmosphere, wherein in the grinding step, the tube 1 is moved in its longitudinal direction (arrow B in the drawing) while the tube 1 is being rotated in its circumferential direction (arrow A in the drawing), and a wheel type grinding member 2 is allowed to abut against the outer surface of the tube 1, thereby producing the heat-exchanger tube for a steam generator for use in a nuclear power plant.
