UNSPSC 24111823: Spherical Pressure Vessel

Spherical Pressure Vessel (Sphere) This type of vessel is preferred for storage of high pressure fluids. A sphere is a very strong structure. The even distribution of stresses on the sphere's surfaces, both internally and externally, generally means that there are no weak points.

UNSPSC 24111823 Spherical Pressure Vessel (Commodity) covers CO2 and compressed-gas storage tanks and related rental, refill, and delivery services that state and local governments procure for pool chemistry, aquatic facility operations, and emergency-service equipment maintenance. Recent solicitations show demand for monthly rental of multiple tank sizes (typically 750 cubic foot and 125 cubic foot portable units) bundled with refill and delivery services on cost-per-pound or monthly-rate structures. County governments and municipalities issue these procurements as informal quick quotes and invitational bids, with pricing structured to remain firm across annual contract terms. Tank removal and decontamination work, including underground storage tank extraction and site restoration, also appears under the code when removal services include tank handling and vessel decommissioning; this work draws state certification requirements and prevailing-wage applicability in some jurisdictions.

Collier County, Florida has posted multiple CO2 rental and refill opportunities under the code within the past four months, most recently solicitation QQ2026144 (posted October 6, 2026, with quotes due July 28, 2026) seeking monthly rental of nine 750 cubic foot and five 125 cubic foot CO2 tanks plus refill and delivery services across six county aquatic facilities. The earlier Collier County Quick Quote QQ2026136 (posted June 30, 2026) followed an identical scope. The City of Meriden, Connecticut issued ITB B027-12 (posted August 12, 2026, bids due September 9, 2026) for removal and decontamination of a 4,000-gallon underground storage tank at a fire department facility, requiring Connecticut state tank-removal certification and a minimum of two years of removal experience. Activity concentrates in Florida and Connecticut in the recent record; broader geographic spread is not evident from the posted opportunities.
