manufacturing method and the steam generator tubes of a nuclear power plant for steam generator heat transfer tube

摘要

To improve the manufacturing efficiency of the [problem] nuclear power plant steam generator tubes and has a annealing step of annealing the A tube 1, a polishing step of polishing the tube 1 outside surface, and a heat treatment step of performing heat treatment of the tube 1 in the environment of oxidizing inhibiting atmosphere, the polishing step, the tube 1 with a circumferential direction while rotating the (in the drawing the arrow A) is transferred in the longitudinal direction (in the arrow B), Hui the tube 1 the outer surface - with polished is brought into contact with abrasive material 2 le type, nuclear to produce steam generator tubes for the power plant. .BACKGROUND 1
