Do I Have to Replace My Bulged Pressure Vessel?

Figure1-Bulged_Shape_of_Vessel-cover Need to replace bulged pressure vessel?
There are a variety of conditions an in-service component (e.g. vessel, tank, piping) can be found in.  The purpose of Fitness-for-Service (FFS) is to evaluate the integrity of an in-service component given a certain degraded condition and rate it for future service considering potential for any additional degradation.  A degraded condition does not have to just be based on corrosion. Sometimes a component can experience a large deformation due to unexpected one-time loads resulting in stresses greater than yield.  When such a large deformation event occurs it is important to inspect the vessel to make sure no cracking occurred during the deformation event.  If it is found that the impacted area is defect-free then the next step is to determine if the component can operate in the deformed shape.One example of a non-corrosion related degraded condition is a bulged tank.  Figure 1 shows an example of a tank that bulged due...
