  • VIBRATION SUPPRESSION MEMBER FOR HEAT TRANSFER TUBE AND ITS MANUFACTURING METHOD, VIBRATION SUPPRESSION DEVICE AND METHOD FOR HEAT TRANSFER TUBE, AND STEAM GENERATOR
    Publication number: 20160061441
    Abstract: In a vibration suppression member for heat transfer tubes, a manufacturing method of the vibration suppression member for heat transfer tubes, a vibration suppression device and method for heat transfer tubes, and a steam generator, a second anti-vibration member (102) includes a first support member (111) provided with a first support surface (112) for supporting an outer surface of a heat transfer tube (66), and a second support member (121) provided with a second support surface (132, 135) and a third support surface (133, 136) for supporting the outer surface of the heat transfer tube (66) with predetermined tilt angles relative to the first support surface (112), the tilt angles being different from each other, the second support member (121) being fixed to a mounting surface (113) of the first support member (111). With this configuration, a vibration of the heat transfer tube (66) can appropriately be suppressed.
