Dynamic response of temperature cycled pipework
The pipework designer shall consider instantaneous maximum value of forces and moments in the original and extreme displacement conditions in evaluating the temperature effect. The layout should be directed toward preventing resonance with imposed or fluid-induced vibrations. However, considerable difference in dynamic response may be encountered when the same excitation is applied to the system in the original and in the extreme temperature conditions. This may occur even if the static state of stress on the pipework is kept within allowable limits. It is shown that when changes in axial forces arise in pipework a spectrum of natural frequencies rather than a single frequency should be dealt with in resonance calculations. It appears that stress changes following temperature increases are noticeable.
