8250m3 Ammonia spherical gasholder was designed and fabricated in accordance with design by analysis. At the hydrostatic test, the gasholder’s 16props are the critical positions of stress. This paper describes the elasto-plastic finite element analysis and following mea surement of stress-strain during this test. The stress level and maximal stress intensity of the gasholder’s prop is determined so that the safe hydrostatic test is
In this paper the analysis for U-tubesheet cracking in gasket groove surface by means of 2- dimmentional finite of ANSYS software was given.The stress check result of structure showed the update- design is reasonable.
