Comments, Questions, and Answers on AutoPIPE's Rotating Equipment Dialog and Report

Item #1: Rotating equipment analysis:

AutoPIPE will automatically take forces and moments from all selected loads and user combinations, and perform a rotating equipment analysis per selected rotating equipment code without having to manually enter loads from each operating condition. After defining operating load combinations as described above, go under Tools/Rotating Equipment. After inputting the equipment ID, select the rotating equipment code. Pump is API 610, compressor is API 617, Turbine is NEMA SM23. AutoPIPE also provides a User defined rotating equipment element in order to analyze equipment using vendor supplied allowable loads for up to four different terminal anchor points.

Depending on the rotating equipment code chosen, AutoPIPE will then ask the user to input the anchor points for suction, discharge, and other external connections as well as shaft axis. The API 610 analysis will require additional input for location of connection on the pump itself (side, top, or end), orientation, Table 2 factor, and center point offsets.

Once this basic information has been entered, AutoPIPE will automatically take the loads from all selected operating loads and user load combinations, and perform the rotating equipment analysis for each of these loading conditions.

Item 02: In the Rotating Equipment Report do the calculated Forces Fx, Fy, and Fz and the Moments Mx, My, and Mz shown for the inlet and outlet connections refer to the global axes or the local axes in AutoPIPE?

Item #3: Does the rotating equipment equations take into consideration the total of the forces/moments + restraint (anchor) or just the value from the Forces & moments AutoPIPE report?

Item #4: What size nozzle can be analyzed using Rotating Equipment module in AutoPIPE?

Item #5: How can I input allowable loads for my nozzles to AutoPIPE and get a report about pump check results?

Item #6: How to define distances of the nozzles relative to the center line of equipment when using Rotating Equipment module?
