High Pressure Storage Container Milwaukee Boiler MFG. Co ASME-NB-INS: 3067

Is this ASME or DOT rated, and what does that allow me to do with it?

This vessel is ASME rated, built to Section VIII standards with National Board number 3067. ASME Section VIII vessels are designed for stationary service—process systems, plant air receivers, storage applications—as opposed to DOT cylinders which are certified for transport. You cannot legally fill and ship this as a cargo container, but it's appropriate for fixed installation at your facility.

What is the MAWP and capacity at service pressure?

Maximum allowable working pressure is 363 PSIG at 650°F. The listing does not specify vessel dimensions, water capacity, or volume, so you'll need to request the nameplate data sheet or National Board Form U-1 from the seller to confirm volumetric capacity and orientation (horizontal/vertical).

What is the requalification or inspection status?

The listing does not state current inspection status, last internal exam date, or remaining certificate validity. ASME Section VIII vessels in continued service typically require periodic internal and external inspections per the jurisdiction's rules—often every 3 to 10 years depending on service and state requirements—but this unit's compliance standing is unknown. Ask the seller for the most recent inspection report and National Board Form R-1 if available.

What should I inspect before putting it into service?

At minimum, verify the nameplate is legible and matches National Board records, perform thickness testing to confirm no excessive corrosion, and inspect all nozzles, manways, and welded seams for cracking or prior repair. An authorized inspector should review whether the vessel meets your jurisdiction's requirements and whether internal service history (ask what it stored) is compatible with your intended process—prior acidic, caustic, or chloride service can disqualify reuse in certain applications.
