02e. "Hydrotest" - AutoPIPE Load Case

The Load> Hydrotest command enables the user to define the hydrotest conditions of a piping system. A hydrotest is a common method for testing the integrity of a piping system before it is put into service. In this test, the piping system is filled with pressurized water and checked for leakage, etc. The Hydrotest option permits a simulation of this scenario. Please note that the AutoPIPE Hydrotest option automatically converts all spring hangers into rigid supports to simulate the holding pin which is still in the spring hanger during the hydrotest.

Note: AutoPIPE 10.01.xx and higher, see the following AutoPIPE help section:
