Specifies the design option to use for spring hanger sizing calculations when multiple thermal operating load cases exist. Each load case is a temperature and pressure combination defined in Operating Conditions.
You can base the design on one or more operating conditions. For example, a two-pump installation where only one pump operates at a time is a good application for multiple load case design.
1 - Operating Case #1
through
9 - Operating Case #9
Designs the hanger for the selected operating load case.
10 - Maximum Load
Designs the hanger for the maximum load from the operating load cases included in No. of Hanger Design Operating Load Cases.
11 - Maximum Travel
Designs the hanger for the maximum travel from the operating load cases included in No. of Hanger Design Operating Load Cases.
12 - Avg Load & Travel
Designs the hanger for the average load and average travel from the operating load cases included in No. of Hanger Design Operating Load Cases.
13 - Max Load & Travel
Designs the hanger for the maximum load and maximum travel from the operating load cases included in No. of Hanger Design Operating Load Cases.
Maximum load and maximum travel can be from different operating cases and can result in conservative hanger design.
-
You can use options 10 to 13 if there is more than one operating state for the hangers. To use these options, you must define more than one design operating load case in No. of Hanger Design Operating Load Cases on the Hanger Design Control Data dialog box.
-
No. of Hanger Design Operating Load Cases sets a global value for the model. You can override the global value for a specific hanger on the Hangers auxiliary panel.
