Abstract

A bar is slotted intermittently, longitudinally at pref. 1/3 and 2/3 of its width, and the edge strips are upset to form saw teeth or the like to provide a structure used to maintain the spacing of tubes in a heat exchanger, esp. in the heat exchanger/steam generator of a light water cooled reactor (PWR/BWR). The bar is in one piece without welding and hence presents little risk of breaking up in service.
