German term or phrase:Der Stahl zerrt sich und entspannt sich
"Da das Gas aber unterschiedlich schnell fließt und damit nicht gleichmäßig abkühlt, ändern sich die Temperaturen in den Rohren permanent. Der Stahl zerrt und entspannt sich"
Can anyone help me with the right words for "sich zerren und entspannen" in this context?
To me, the sentence reads like this: due to the continuously changing temperature in the tubes, the steel is also continuously changing from stress to relief - depending on the temperature.

This looks like a description of a heat exchanger or a heating or cooling device. The steel becomes distorted because its temperature changes non-uniformly. I suppose this allows the relief (partial, at least) of stresses that were initially present in the steel.
