Heat Rate PWHT processes typically reach temperatures above 450 degrees Celsius for one hour per inch of thickness, making it essential that heating and cooling rates match those required by material type, component size\/configuration and desired soaking temperatures. Excessively fast heating or cooling rates could result in unacceptable distortions and thermally-induced stresses if they exceed appropriate levels. For large and unwieldy fabrications, using trestles or supports may be necessary during local plasma wand heat treating (PWHT). When designing such supports, take into account differential expansion\/contraction capabilities of components as well as construction of these trestles from materials which won’t be damaged by high PWHT temperatures.
