Metodología de Diseño de una Escotilla de Inspección para Recipientes a Presión

This paper aims to describe the design methodology used for equivalent stresses assessment in pressure vessels through the application of the finite element method and based on the resulting considerations, the creation of an inspection hatch design.Computer simulation technique and analytical checks were carried out.  As the result,  points of comparison were generated and a systematic study to test the behavior of the resulting forces based on geometric modifications were developed.    A model along with three proposals of Manhole was defined.  Inspection hatch configuration respondsto circular, elliptic-longitudinal and elliptic-transversal format.  Thus,  the layout of tensions about the subject of study was confirmed and also, a more inclusive procedure compared with conventional method, which is based on simplified calculation expressionswas defined.
