What does M.A.W.P. stand for?

• A. Minimum Allowable Working Pressure
• B. Maximum Allowable Water Pressure
• C. Maximum Allowable Working Pressure
• D. Maximum Allowable Warming Pressure

Answer: (C)

Maximum Allowable Working Pressure is the highest pressure at which a pressure vessel or system is permitted to operate safely, as determined by its design and the applicable codes. This limit comes from the weakest part of the system and sets the operating bound for materials, thickness, and safety devices. You’ll typically see this value on the equipment’s nameplate, and it guides what operating pressures are allowed in routine service. The test pressure used to verify integrity in a hydro or pneumatic test is usually higher than this value to demonstrate the vessel can withstand overpressure, but normal operation must stay at or below the MAWP. The other phrases don’t reflect the standard term used in codes and practice, which is why they aren’t correct.
