Obiettivi dell'insegnamento
The aim of this course is to make students acquainted with the design basic criteria and the construction, processes and test practice of industrial pressure vessels. The skills developed at the end of the course are the preliminary design of the layout of the vessel, according to Standards, the stress analysis computation and experimental practice, the basic knowledge and handling of NDT procedures.

The course is composed by theory, practice and laboratories. Theory deals with : the stress analysis of the main vessel components; the non destructive techniques for the evaluation of defects in structures and the Standards requirements, with particular care for the welding design and testing. Practice proposes several applications of stress analysis of vessel components, the design by Rules and by Analysis in the case of the heat exchangers, according to TEMA and ASME Standards. Laboratories deal with the experimental demonstration and practice of stress analysis by strain gauges, and with the calibration of ultrasonic transducers and the NDT application to welded joints.
