Minature Pressure Vessel

[MLamontagne]

I am designing cast aluminum pressure vessel/air reservoir that has a volume of 30 in^3 and is designed be pressureized at a maximum of 120 PSI, this air reservoir also has a built in pulse valve. I have been reviewing Section VIII and in U-1(c) it is above the 15 PSI limit but below the 6in crossection limit, and in U-1(j) is is way below in the volume limit for U-1(j)(3). Does it need a stamp "U" or "UM" or any stamp?

MLamontagne, likely it need not be stamped, but the jurisdiction where it is to be installed has the final say. See U-1(c)(1).

Mike

The problem with sloppy work is that the supply FAR EXCEEDS the demand
