Abstract
A support bar for tubes in a heat exchanger, such as the U-bend tubes in the U-bend region of a recirculating, nuclear steam generator, provides positive restraint in both the in-plane direction of the tube planes and the out-of-plane direction. The bar has pairs of parallel surfaces aligned with first and second axes such that the bar may be positioned with either axis arranged parallel to the tube planes. The bar can be used in place of other types of tube support bars, and can also be used as an auxiliary bar for installation into a fully assembled heat exchanger to provide additional support to supplement other tube support arrangements.
