Default Settings - General
Skip Factor A Input: Factor A, for external pressure calculations, is automatically calculated for cylinders, cones, and heads as appropriate. Clear this box to be able to override this calculated value for cylinders and cones. Once this value has been manually overridden, it will no longer automatically update. This only affects the calculation based on nominal dimensions and not the calculation based on required thickness.
Skip Factor B Input: Factor B, for external pressure calculations, is automatically calculated for cylinders, cones, and heads as appropriate. Clear this box to be able to override this calculated value for cylinders and cones. Once this value has been manually overridden, it will no longer automatically update. This only affects the calculation based on nominal dimensions and not the calculation based on required thickness.
Show Country: Select this box to add the Country field to the Company tab in the Vessel screen and print the country on the cover page of the report. The company information on the Company tab of the Vessel screen is what prints on the cover page of the report.
Auto enter a description: Select this box to enable automatically created generic descriptions of new vessel components. These descriptions will include the component type and number (e.g., Nozzle 5). If the box is not checked, the default descriptions for new components will be blank.
Consider Flange Rigidity Index: Select the box to perform the flange rigidity code check per Appendix 2-14. Though this code check is now required per Section VIII, Division 1, it was optional in the past and this field allows the user to decide whether or not to consider the requirement.
Lock Wm Value to Minimum: Select this box to force the bolt load values, Wm1 and Wm2, to the minimum required in Appendix 2. Clear this box to increase the bolt load values. For cases where flange pairs are used, these values must be manually matched across the two flanges and this box should be cleared.
“Job No: “ prompt: This is a global setting that affects the “Job No:” label that appears in the upper left corner of the component reports and the vessel screen General tab. It also appears near the top of the cover page of the report.The text entered here will display in those locations.
Ring Stiffener Type: Select the shape of the stiffening ring (e.g., W-shape, Angle, etc.).
ASME Flange Type: This drop-down contains the rated flanges from B16.5 with the exception of blind. When creating a 24" or smaller rated flange that has cylinder, reducer, nozzle, or head as its host, the ASME flange type will default to this selection. When creating a rated flange that has another flange as the host, it will always default to blind when the size is 24” or less.
ASME Flange Series: B16.47 only includes weld neck series A and B and blind series A and B flanges. When creating a 26" or larger rated flange that has cylinder, reducer, nozzle, or head as its host, the ASME flange type will default to “Weld Neck Series” plus this selection. When creating a rated flange that has another flange as the host, it will always default to “Blind Series” plus this selection when the size is 26” or more.
