CAESAR II users can specify a value for the system hydrotest pressure. The entry for this pressure can be found at the bottom of the piping input spreadsheet, just below P1 and P2. Additionally, an entry field for this pressure also exists on the extended operating conditions dialog. Both of these hydrotest pressure fields are shown in the figure below.
When a hydrotest pressure is specified, CAESAR II will recommend a load case consisting of WW + HP. The components in this load case are:
- WW: Pipe weight filled with water. This includes insulation and/or refractory if specified.
- HP: The specified hydrotest pressure.
For this load case, it is assumed that any spring hangers are locked against movement. A typical set of load cases, including a hydrotest case is shown in the figure below. Note that “Case 1” is the hydrotest case.
