What is a generic CRN design?
A generic CRN design describes variable dimensions, materials, and feature locations of pressure equipment. For example, a generic vessel CRN design can generally describe a variable shell length, all possible nozzle locations and sizes, together with proximities of nozzle groups etc.* For vessels, generic designs cannot vary the head shape, shell diameter, maximum pressure, maximum temperature, or minimum temperature. For generic fittings, many options are allowed, generally enabling you to register a whole series of fittings with one generic drawing specifying a range of dimensions, materials, and even design pressures.* *Each situation is somewhat unique and requires careful consideration. Other restrictions may apply subject to regulator acceptance.
