Use the Result Table option to display the stress values for the selected stress schedule (click the Result Table button, and then click the make table button). In hydrostatic pressure testing, a liquid is used to check for leaks before putting a pressure vessel or pipeline into service. The R factor is required if the allowable stress at the test temperature is greater than the allowable stress at the design temperature. Inspectors crawl all over the unit to look for drips. The test pressure should be less than or equal to 1.5 x the rated pressure of the lowest rated component in the system. For pressure testing of a component that will be used in service, the pressure is usually 1.3 - 1.5 x design pressure, which keeps the material from yielding, but subjects it to more stress that it will see in service. Close this window and log in. See our buoyancy calculator for more information. You can verify it by following the next procedure: To increase hydrostatic fluid pressure at a specific point, we have to increase the vertical distance between the water source and the point.
