Mechanical characterization of materials for pressure vessel

The problems appeared in the operation of the pressure equipment, determined the appearance of several study methods for the chemical composition and of some mechanical properties. In the Romanian literature we do not find data on the study of these issues. This report presents several studies on the problems that arise in the operation of pressure equipment in the international literature. One of the important properties of materials used in the construction of pressure vessels is their corrosion resistance. It is required that, in the most severe conditions, the corrosion rate does not exceed 0.4 mm / year. Both metallic and non-metallic materials are used in the construction of pressure vessels. This article aims to conduct experimental research on the mechanical properties of some materials used in the manufacture of pressure vessels: P195 GH - EN 10216.2 si 16 Mo 3 - SR EN 10028.
