Designing Non-Circular Nozzle Openings
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 Code rules. COMPRESS and INSPECT use the nozzle orientation and location input to determine the governing plane of reinforcement, F factor (see Fig. UG-37) and chord length. Unlike competing software, COMPRESS and INSPECT save time and reduce errors by automatically calculating the chord opening length for you.
If you don’t have software that calculates non-radial nozzle openings for you, it’s time to explore the benefits of COMPRESS. Find out more by emailing firstname.lastname@example.org or calling (941) 927-2670.
