The non-dimensional design method of pressure vessels may simplify the design process and reduce the workload, and can be substituted for the traditional method. The theory and steps of the non-dimensional design method were presented based on the present design methods. For this method, two kinds of non-dimensional parameters were constructed through introducing fidueial dimension and pressure, of which the comparative computing pressure would be the main factor. Aeearding to NDDM, several typical structures of the main parts were analyzed and translated. The non-dimensional formula of the cylindrical shell, hemispherical head and fastener structure were obtained. The important contents in the developing step were also finished, which were the basis of the NDDM application step.
