Pressure Vessel Design Charts

Although not suited for final vessel calculations, design charts can be very useful for preliminary design and quotation purposes. The charts on this page (in pdf format) provide pressure ratings, weight and volume for various sizes and wall thicknesses of components.

To use these charts, you will need to know the rated stress for the materials you will be using. Currently, the rated stresses for pressure vessels are found in the Boiler and Pressure Vessel Code Section II part D - about six pounds of paper covering thousands of materials. The material design temperature is also required to lookup material properties. You will also need to know what joint efficiency to use.
