## ﻿maximum allowable working pressure of boiler

### What do you mean by working pressure of a boiler? - Quora

Steam boilers are classified as either Section 1 (> 15 PSIG) or Section IV (≤ 15 PSIG) depending upon their Maximum Allowable Working Pressure (MAWP) design. Meanwhile, an ASME Section I Power Boiler may also be designed as a hot water boiler where the maximum temperature is above 250°F and/or the MAWP is above 160 PSIG.
