Abstract
The selective corrosion of a pressure vessel is facilitated to reduce the adverse consequences of a corrosion induced vessel wall rupture. A corrosion resistant coating is applied to the pressure vessel except in a region within the bounds of a restrictor located within the vessel. The region may have a reduced wall thickness. An accelerant material may be applied to the region to facilitate corrosion. Any corrosion induced rupture will occur in the region, and the pressure release due to rupture of the vessel wall will be controlled by the restrictor.
