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, a Commodity code, encompasses tanks and pressure vessels state and local governments procure for water treatment, facility operations, and industrial storage—including CO2 storage and delivery tanks, microfiltration feed tanks, cryogenic nitrogen storage systems, and general-purpose liquid storage tanks. Recent solicitations show counties and municipalities buying refurbished or replacement tanks ranging from portable 125-cubic-foot CO2 cylinders to 12,150-gallon microfiltration systems and five-million-gallon prestressed concrete water storage tanks, with vendors handling rental, delivery, refill, installation, hydrotesting, and disposal. Issuing bodies include county operations departments (Collier County, Pinellas County, Gwinnett County), city water utilities (Marietta), public-university procurement (University of Wisconsin-Eau Claire), and county solid-waste facilities. The code sees activity across multiple jurisdictions acquiring tanks for pool maintenance, industrial water treatment, nitrogen laboratory supply, water distribution infrastructure, and temporary or permanent operational storage.

Recent activity concentrates in Florida and Georgia, with the most frequent solicitations from Collier County, which has posted at least two Quick Quote notices for CO2 tank rental, refill, and delivery services at six aquatic facilities (response dates July 8, 2026 and July 28, 2026). Pinellas County issued an ITB for replacement of a 12,150-gallon microfiltration feed tank with installation and hydrotesting (response date April 30, 2026, estimated value approximately $103,722). Gwinnett County solicited quotations for four 5,000-gallon and two 1,635-gallon Norwesco-brand storage tanks (response date March 16, 2026). The City of Marietta requested sealed bids for design and installation of a five-million-gallon prestressed concrete water tank including demolition of the existing 4.3-million-gallon tank (response date February 24, 2026). The University of Wisconsin-Eau Claire sought a microbulk cryogenic nitrogen storage tank and delivery system (response date April 24, 2026). Procurement vehicles range from informal Quick Quote to sealed-bid ITB and RFB, with most solicitations structured as low-bid awards and firm pricing through contract end dates in 2027.
