3.1 Calculation of gradients due to thermal transients

In the construction codes commonly used to design piping systems, temperature is only taken into account when determining the permissible stress, on which the pipe thickness depends, and when calculating stresses due to expansion prevented by anchors. Stresses due to thermal gradients in the metal, caused by temperature variations, are generally not taken into account, which means that temperature variations, whether during...
