661PRO performs a finite element analysis of nozzles on rectangular header boxes for air-cooled heat exchangers per API 661. Several types of nozzles are allowed, including circular, oblo-swaged, tapered and nozzle-reinforced (barrel). The tubesheet area stresses can be approximated by specifying the number of holes, pitch, tube diameter and thickness, effective elastic modulus and effective Poisson’s ratio.
661PRO v2.1 is only available with a license of FEPipe v10.1. It is not sold as an independent program.
