UNSPSC 24111818: Tank seal

Annular seal designed to prevent escape of vapors from floating roof storage tanks. Includes wiper assemblies

UNSPSC 24111818 Tank seal (Commodity) encompasses tank rental, refill, and delivery services for industrial and institutional gas applications, as well as tank removal and decontamination work. State and local governments are buying two distinct service lines under this code: ongoing rental and maintenance of pressurized gas tanks (primarily CO2) for facility operations, and one-time removal, decontamination, and disposal of underground storage tanks at municipal infrastructure sites. Collier County, Florida, and the City of Meriden, Connecticut, represent the issuing-body mix on recent solicitations—a county government and a municipal fire department managing routine pool and aquatic-center support and emergency infrastructure remediation, respectively. Vendors bidding rental work must provide monthly tank delivery, refill services on a per-pound basis, and maintenance across multiple service locations; vendors bidding removal work must hold state certification, demonstrate minimum experience in tank decontamination and soil remediation, and manage excavation, testing, and site restoration as part of a comprehensive removal plan.

Recent activity concentrates in Florida and Connecticut. Collier County, Florida posted two overlapping Quick Quote solicitations for FY27 CO2 tank rental, refill, and delivery (QQ2026144, posted October 6, 2026, with quotes due July 28, 2026; and QQ2026136, posted June 30, 2026, with quotes due July 8, 2026), each covering nine 750-cubic-foot and five 125-cubic-foot tanks across six county parks and aquatic facilities under monthly rental with firm pricing through September 30, 2027. The City of Meriden, Connecticut posted an Invitation for Bid (ITB B027-12, posted August 12, 2026, due September 9, 2026) for removal and decontamination of a 4,000-gallon (or 3,000-gallon, per specification variance) double-wall underground storage tank at Engine Company #2, requiring Connecticut state certification for tank removal and a minimum of two years of removal experience; a local-vendor preference and prevailing-wage requirements apply. Award on both Collier County solicitations flows to the lowest responsive quote; Meriden awards to the lowest responsible bid with liquidated damages of $500 per day for delays.
