Becht conducts rerates of pressure vessels for different operating conditions, e.g., higher pressures and/or higher or lower temperatures. Rerates are permissible under certain conditions that in the US are specified by the NBIC (National Board Inspection Code). Analysis is required to demonstrate the vessel meets ASME Code rules at the new design conditions. An inspection is also required to determine if deterioration has occurred and if found, a Fitness-for-Service analysis per API 579 is conducted to determine if repairs or component replacement are necessary. In addition we have conducted studies for clients who want to bring a used or non-code stamped vessel into their plant. These types of studies require meeting the regulations set by the jurisdiction (usually the State). Whether it is a rerate or "state approved pressure vessel," Becht can provide the full service, i.e., analysis, inspection, fitness for service and pull together the full package for jurisdictional or state approval.
