May/June 2011 Inspectioneering JournalBy Joey Poret at Chevron
The reliability of equipment is determined by several factors including equipment condition, service history, failure modes, and maintenance. A subsection of equipment reliability is the ability to detect defects before they contribute to the failure of the equipment. In many cases, Nondestructive Testing (NDT) methods are utilized to detect and monitor these defects both in-service and during fabrication.

MI Inspection During Capital Projects Promotes PSM Compliance, Corrosion Rate Accuracy and Improved BudgetingMay/June 2011 Inspectioneering JournalBy Paul F. Schubert, Ph.D. at SGS North America Industrial Services, and Travis Keener, P.E. at SGS North America Industrial Services
Putting off the initial inspection (i.e. baseline) of piping and vessels in a new process unit is both common and problematic. The tendency of owners is to rely on the nominal thickness because the actual original thickness was either not measured or not recorded for calculating corrosion rates after the first wave of thickness readings are taken with the equipment having been in service for some period of time.
