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.

Finite Element Analysis

Becht Finite Element Analysis
lick Valve for More Info

Becht Engineering has developed a reputation as one of the premier providers of Design-By-Analysis services.  We have a deep reservoir of staff that perfrom finite element analysis using commercial programs such as ABAQUS, ANSYS, SolidWorks and products of Paulin Research Group.  Types of analysis include linear and nonlinear analysis, stress, heat transfer and dynamics including seismic.

Given the many analytical tools available, we are able to choose the most efficient and cost-effective tool for the task at hand; for example, we frequently use non-linear analysis to develop more efficient equipment designs and/or to demonstrate that existing equipment is fit for service. Our extensive code expertise enables us to provide authoritative interpretations of the analysis results. Our experts include such frequently published engineers as Greg Hollinger, Trevor Seipp, and Dr. Charles Becht.
