Fort Hunter Liggett Polisher Tested to Withstand Pressure

The gasifier and polisher vessels for Fort Hunter Liggett will undergo rigorous testing prior to their installation at Fort Hunter Liggett. Both vessels must be able to safely withstand high temperatures and contain large volumes of syngas. To ensure that they are up to the challenge, the vessels will be hydro-tested per American Society of Mechanical Engineers (ASME) boiler and pressure vessel codes.

The hydrostatic pressure test is performed by pumping a carefully measured volume of water into the closed container, maintaining this pressure for ten minutes, and monitoring the effects on the vessel. Engineers monitor the vessel performance by searching for leaks or signs of failure along key fault lines in the vessel. The picture below shows the polisher hooked up to monitors and water lines in Andy J Egan’s shop in Grand Rapids, Michigan.
