Análisis deun interno tipo bridade un recipiente horizontal a presión utilizando elementos finitos

Abstract

This work presents the stress analysis at the flange-type intern element in a pressure vessel which works at 175 °F and 135 psig of pressure, by using the Finite Element Method. This equipment belongs to flow stations and has the main function of separating gas and water from a production fluid. By effect of a contingency, some cracks may arise in the material between the holes of the intern. The mechanical stress distribution around the holes of the intern was estimated using static structural analysis of ANSYS v18.2. The results show that the stress concentrator is located at the intern central orifices, and the range of stress is 25 MPa to 137.5 MPa. In order to continue the operation of the equipment, it is necessary to weld a reinforcing pad.
