- Abstract
The stresses in an expanded element are briefly examined, and the effect of differential expansion between tube and plate made clear. The effects of annealing and cold work on the properties of copper are briefly noted. Tests are reported showing the holding power of copper tubes expanded into steel tubeplates following various procedures. Recommendations are made as to annealing temperatures for tubes, optimum expansion and safe limits of working temperatures. A note is added on the properties of cupro-nickel tubes, and on some experiments indicating their reliability expanded into steel tubeplates for temperatures up to 500°F.
