Overpressure Protection of Pressure Vessels

WebbPressure Relief valves (PRV) are used to relieve the pressure in these equipments before it can cross the maximum allowable working pressure, thus protecting the equipment from damage. The pressure relief valve set point should be such that relief valve will open before the maximum allowable accumulated pressure (MAWP) is reached in the vessel.

Webb20 nov. 2024 · Maximum allowable working pressure (MAWP) is the design pressure rating of the equipment that the PRV protects. Set pressure is the pressure at which the PRV is set to start to open. Set pressure can equal, but not exceed MAWP. Reseat pressure (seal-off pressure) is the pressure at the valve inlet after closing. Webb19 okt. 2015 · In summary, tanks with an MAWP higher than 3 bar have the “set-to-discharge” pressure of the PRV set at 10% above the MAWP ( 110% of two-thirds of the Test Pressure ). This applies to tanks conforming to Tank Instruction T11, which make …

Webb9 nov. 2009 · Then they will determine the maximum allowable working pressure (MAWP) of the vessel, and if it’s an API vessel, stamp that MAWP value right onto the vessel’s nameplate. The fabricator will ensure that the MAWP is greater than or equal to the design pressure.
