Abstract

GUALDA, Néstor J; SANZI, Héctor C  and  ORTIZ, Luis. Stress Analysis by means of Finite Elements of a Ball Valve during the Hydrostatic Test, and its Experimental Verification. Inf. tecnol. [online]. 2010, vol.21, n.5, pp.39-44. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642010000500006.

The stress and deformation analysis in the body of a ball valve of diameter 8", class 600, during the hydrostatic test, using the finite elements method is done. The results are verified through experimental stress analysis method, using strain gauges. For the finite elements method the software Cosmos/M and information obtained during the experimental analysis were used. The experimental tests were carried out in a press type test machine, placing strain gauges in the body of the valve at certain points of interest. The valúes of deformation obtained allowed validating the application of the finite elements method.

Keywords : stress analysis; finite elements; ball valve; hydrostatic test; strain gauges.
