Abstract
A system for supporting a bundle of tubes against lateral movement in a heat exchanger, such as a nuclear power plant steam generator, wherein spring collar devices positioned at intervals along the tubes permit lateral movement of the tubes but prevent any relative movement between the tube and its associated spring collar device. Any lateral movement is between adjacent spring collar devices. With this arrangement, fretting and corrosion between the outer surfaces of the tubes and their lateral support members are substantially eliminated.
