Analysis of the techno-economic implications generated by the selection of manufacturing codes of pressure vessels for high demanding applications

The selection of the manufacturing code in components for high demanding applications is crucial. A new methodology is developed to solve the problem of manufacturing codes selection. This methodology allows to obtain an integrated approach that considers a technical evaluation that consists of quantifying the stringency of technological requirements together with an economic study. By the implementation of the new methodology, an alternative that combines the benefits of both standards from a multi-criteria perspective based on functional and economic criteria has been proposed. This proposal represents a saving of 5.8% with respect to the use of KTA standards, without diminishing of technical stringency.
