Recently at one of our plants we had a 5 year PHA revalidation. During this PHA the 3rd party facilitator question one of our vessels that operates at 780psig @108F to 115F base on ambient conditions. The name plate on the vessel indicates design condition of 1440psig @ 100F. What should be the right course of action for this vessel, is rerating the vessel to cover the 10 to 20 degree difference in temperature required? the relief valve on this vessel is set to 950psig.
