Hillside Nozzle Design

Due to process and pipe routing considerations, nozzles on pressure vessels and heat exchangers are frequently placed in non-radial orientations. These non-radial nozzle to vessel intersections create obround openings which require additional geometric calculations to meet ASME Code rules. Put another way, the nozzle opening diameter d used for reinforcement calculations is not fixed by the nozzle size; it changes every time a process engineer re-locates the nozzle on the equipment. COMPRESS and INSPECT use the nozzle orientation and location input to determine the governing plane of reinforcement, F factor (see Fig. UG-37) and opening chord length (d).

Competing software products expect you to manually calculate the opening chord length, d and type it in. COMPRESS and INSPECT save time and reduce errors by automatically calculating the opening chord length for you.
