Abstract:

The calculation results of the developing step in the nondimensional design method can be conveniently and directly applied to designing pressure vessels. Using the obtained formula of the nondimensional design method,the results of the cylindrical shell, hemispherical head and fastener structure were attained, which were the relational formula or curves between comparative size and computing pressure. In order to validate the results, two pressure vessels with thesame structure and different computing pressure and size were all designed. The correctness was  checked by the present standards. 

Key words: pressure vessels; design method; non-dimensional parameters
