In this study, the possibility to relax the maximum allowable load on MHI centrifugal compressors and steam turbines is investigated based on MHI design philosophy of turbomachinery, MHI experience and analysis of quantitative influence using FEM (Finite Element Method) of typical machines with piping load of 1.85 times allowable limit specified by NEMA SM 23. Various key components including nozzle deformation, stress level, clearance and misalignment of shaft end are examined and, as a result, the bottleneck which should be taken into account for MHI centrifugal compressors and steam turbines is clarified in case of excess piping load. Finally, applicable solutions from machine manufactureâs side are suggested in order to relax this specification of piping load on turbomachinery.
