Drawing Number: The drawing number associated with the component. This does not refer to any drawings that are generated in the software and it is listed here for the user's reference. It will default to the drawing number input on the vessel screen.

Mark: A shorthand reference for the component. It will also appear in the component report. The default entry will be an abbreviation of the component type and the component number. For example, the second jacket shell for the vessel will start with a mark SJ2.

Clamp Description: The label given for the component. It will appear in the component pane, the report dialog, the summary pane, and at the top of the component report. This will default to the component type and component number. For example, the second clamp for the vessel will start with a description of Clamp 2.

Design Pressure: The internal design pressure (pressure on the concave side). This value is gauge pressure. When “Solve for Thickness” is selected, this value is an input and should not include static head. When “Solve for Pressure” is selected, this value is a result. In the latter case, it represents the total internal pressure (design pressure plus head) that the component can handle and meet code in the absence of any other loadings.

Static Head: The internal pressure (pressure on the concave side) resulting from the static head of the fluid. The user must determine this value and input it accordingly. It will be added to the Pressure input and the sum will be used in the internal pressure calculations for the component. This field will not be present when “Solve for Pressure” is selected.

Temperature: The maximum mean metal design temperature for the internal pressure case as defined in UG-20(a).

CA: Corrosion allowance on the inside of the component (concave side).

Hub Configuration / Lug Configuration: Select a configuration option in each section. Hub configurations (a) and (b) include a double hub taper; while (c) and (d) have a single hub taper.  Hub configurations (a) and (c) include a groove; while (b) and (d) do not.  For more information on the choices listed, refer to the figures in Appendix 24.
