Title: VIBRATION SUPPRESSION MEMBER FOR HEAT TRANSFER TUBE, MANUFACTURING METHOD THEREFOR, DEVICE AND METHOD FOR SUPPRESSING VIBRATION OF HEAT TRANSFER TUBE, AND STEAM GENERATOR
Abstract:
A vibration suppression member for a heat transfer tube, a method for manufacturing a vibration suppression member for a heat transfer tube, a device and a method for suppressing vibration of a heat transfer tube, and a steam generator, wherein a second vibration prevention member (102) is configured with a first support member (111), which has a first support surface (112) supporting the outer surface of heat transfer tubes (66), and a second support member (121), which is affixed to an attachment surface (113) of the first support member (111), and has second support surfaces (132, 135) and third support surfaces (133, 136) that have a prescribed angle of inclination with respect to the first support surface (112) and have been set at mutually different angles of inclination, and that support the outer surface of the heat transfer tube (66). Thus, the vibration of the heat transfer tubes (66) can be suppressed appropriately.
