Hydropneumatic Tanks

Hydropneumatic Steel Tanks

ASME Pressurized Steel Tanks: 200-30,000 Gallons

Hydropneumatic tanks are ASME-certified vessels for storing pressurized water and air. Starting at 2,000 gallons, these tanks are often horizontal and lined with polyurethane or epoxy to store potable water safely. They ensure consistent water pressure, provide an "on-demand" water supply, and act as buffer tanks in high-capacity pumping systems.

ASME Tank Specs: Codes, Fittings, and Custom Options

1. Tanks are built in accordance with the latest edition of the ASME Unfired Pressure Vessel Code. All ASME vessels are welded, tested, and inspected per ASME Section VII, Division I-UG 27.
2. Thicknesses are calculated per ASME Section VII, Division I-UG 27.
3. Fitting details/locations are typical.
4. An 11" x 15" elliptical manway is typical for an inspection opening. All lined vessels require a 12" x 16" minimum elliptical manway.
5. Tanks with different/larger volumes, dimensions, and pressure ratings are available upon request.
6. ASME stamped vessels are required in most states. Where applicable, non-code hydropneumatic tanks are available upon request.
