Last Updated: 2022.2Axial Load: The load per unit length on the junction. The check box to the right of the field toggles this value between a tensile load and a compressive load.7
For Internal Pressure
Internal 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. This defaults to the lesser of the cone or cylinder internal pressure. It can be changed.
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. This defaults to the lesser of the cone or cylinder static head. It can be changed.
Axial Load: The load per unit length on the junction. The check box to the right of the field toggles this value between a tensile load and a compressive load. This value affects the Internal Pressure case only.
For External Pressure
External Pressure: The external design pressure (pressure on the convex side). This field is disabled and locked to the value from the cylinder at the junction.
Axial Load: The load per unit length on the junction. The check box to the right of the field toggles this value between a tensile load and a compressive load. This value affects the External Pressure case only.
Use Custom A: Checking this box will enable the "Custom A" field for input and the Custom A value will be used for A in the Line of Support calculations instead of the A value determined by the software.
