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.
Comments, Questions, and Answers
- Why are my V-stops not allowing lateral movement during a Hydrotest load case?
Answer: From AutoPIPE online help: A non-linear static analysis cannot be performed on the hydrotest loadcase i.e. friction, support gaps and soil yielding are ignored. - Is there a method to perform a Hydrotest as a non-linear analysis?
Answer: The following method overcomes the hydrotest load limitation in AutoPIPE (which cannot account for nonlinear gaps, friction and soil in the static analysis).
Please see the following AutoPIPE help section:
