Vasos de pressão: comparação do dimensionamento de componentes entre as normas ASME seção VIII divisão 1 e EN 13445 aplicado à indústria de papel e celulose

Abstract

To guarantee the structural integrity and guarantee safety during the operation of a pressure vessel, it is essential to use a technical standard. Although it is not an everyday step applied in mechanical engineering offices, choosing a sizing code is essential to achieve material reduction during the design phase. This is possible because each code has its own methodology. Knowing this, the objective of the following work is to compare the ASME Section VIII Division 1 and EN 13445 part 3 standards, só that it is possible to visualize the pros and cons of each of them from the perspective of structural mechanics. The comparison will be performed using calculated variables such as the minimum required thickness and the weight. The present work concluded that the most efficient standard is EN 13445, once the use of this standard can generate mass savings of up to 30.3%, 47.0% and 53.4% for carbon steel, stainless steel and duplex steel, respectively.
