: Positive pressure must be continuously monitored and maintained throughout the entire shutdown period. This guarantees that even if small leaks exist, oxygen cannot migrate into the system. 2. Dry Air Purging (Excluding Liquid Water)
Residual stresses from welding, cold working, or thermal cycling during operational shutdown provide the mechanical driver needed to propagate the cracks along the sensitized grain boundaries. nace sp0170 pdf
