MAWP and Safety Valve Set Pressure - Boiler and Pressure

05/05/2009 · There will be an electromatic relief valve on the superheater pipe in addition. This valve will be set at lower pressure than the lowest set safety valve on the superheater. The reheater pipes both at the inlet and outlet side will also have safety valves which can range from two to eight both in the inlet and outlet of the reheater put together.

23/08/2017 · PSV Safety Valve Setting Example. If MAWP of a boiler is 200 Psi & we want to install 3 PSV valves two on the drum and one on the super heater, the setting will be as according to ASME codes. One safety valve will be set at the pressure of 200 psi, second at 206 psi (3%) at the drum. Super Heater safety valve pressure will be set at 185.4 (10% 206-20.6) (range 206×10/100)
