PROBLEM TO BE SOLVED: To provide a method for surface treatment a of a heat transfer tube of a steam generator capable of executing a treatment for inhibiting elution of Ni from a heat transfer tube of a steam generator by using an inexpensive apparatus of a very simple constitution at reduced costs and man-hours for treatment work. SOLUTION: The method for surface treatment of a heat transfer tube of a steam generator made of a Ni-Cr-Fe system alloy comprises the steps of assembling a heat transfer tube in the interior of a steam generator and circulating a surface treatment liquid in the heat transfer tube via a heat-temperature fluid outlet chamber and a high-temperature liquid inlet chamber to form a surface coating on the inner surface of the heat transfer tube.
