Abstract
A thin-walled resilient sleeve is disposed between each group of support plates and a pipe at the center of the pipe coils. One end of the sleeve is secured to the central pipe while the other end of the sleeve is secured to the support plates. The sleeves enable the support plates, which in operation become hotter than the pipe coils, to expand towards the central pipe, with a consequent appreciable reduction in heat expansion of the pipe coils and therefore in bending stressing thereof.
