November/December 1995 Inspectioneering JournalBy David A. Mauney at Southwest Research Institute
Many critical industrial plant components are in the aging part of their life cycle. This is because many of the US plants were built during the 50's and 60's. In the aging portion of life, the failure rate is exponential. This creates a need for predictive maintenance expenditures to maintain reliability

Evaluations of aged and critical service vessels such as FCCU's and Delayed Cokers have been aided by the addition of two physical measurements referred to as structural characterizations. These are placed in perspective with the classic description provided by John Reynolds in his presentation of a multidisciplinary team effort in Fitness for Service (FFS) evaluations.

In our inspection organizations, we have identified a number of critical success factors (CSF's) which are vitally important if we are to achieve the level of pressure equipment reliability and integrity to which we aspire. One of our CSF's is the level of service provided to our refineries and chemical plant sites by our Nondestructive Examination Technical Direction Team.

Nelson Curve changes in the late 1980's provided cause for Shell Oil Company to look at more reliable NDE non-destructive evaluation methods for assessment of materials/equipment in high temperature hydrogen service. The primary change motivating Shell was the lowering of the C-0.5 Mo steel Nelson Curve to the carbon steel level.
