METHOD FOR PRODUCING STEAM GENERATOR HEAT TRANSFER TUBE FOR NUCLEAR POWER PLANT, AND STEAM GENERATOR HEAT TRANSFER TUBE

摘要

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.
