TL;DRAbstract

The effect of spacing and displacement on the expected life of double tube sheet condensers is described. A simple jig having a fixed and movable tube sheet cornected by a single 70: 30 or 90: 10 copper--nickel condenser tube is used to study the various factors. Relationships between spacing, displacement, and cycles to failure are presented. It is concluded that a 3-in. spacing is necessary to fulfill the prescribed conditions of a 70: 30 tube operating at a displacement of 1/16 infor a minimum of 4,000 cycles. (auth)
