Maximum Allowable Working Pressure [MAWP] vs. Maximum

The MAWP is a typical definition used in ASME BPVC (ASME Boiler and Pressure Vessel Code) and a number of other codes which refer to it. The MAWP is the maximum gauge pressure permissible at the top of the equipment in installed operating position and at a designated temperature.

Difference Between MAWP and Design Pressure

The MAWP will be changing with time because of corrosion and vessel fatigue. Design pressure depends on the kind of system (fuel, water, steam, etc.) that is used in the vessels. Both the design pressure and MAWP have many applications in steam drums, boilers, piping, and different types of pressure vessels. Summary:

MAWP and Safety Valve Set Pressure

I know it's fairly low pressure but using a "safety valve" to restrict operating pressure doesn't sounds like a good idea to me. However setting any operational limit is up to you - it should not affect any ratings of the vessel and you could have any pressure you like equal to or less than the MAOP which itself can be set anywhere equal to or less than the design pressure.
