UNSPSC 24111807: Expansion tanks

UNSPSC 24111807 Expansion tanks is a Commodity code that covers pressure-vessel equipment used in hydronic heating, cooling, and plumbing systems to accommodate fluid volume changes. State and local governments procure these tanks as components in facility infrastructure upgrades, maintenance programs, and new construction projects—particularly for schools, municipal buildings, water utilities, and transit facilities. The tanks function as closed-system accumulators that prevent overpressure and water hammer in piping networks, and purchases typically occur as part of broader mechanical, HVAC, or plumbing system contracts or as replacement parts during system refurbishment.

The source does not contain records of recent state and local contract opportunities posted under this code. Without posted solicitations naming issuing bodies, geographic regions, or response dates, no representative recent activity can be characterized. The code shows limited visibility in current state and local procurement tracking, suggesting either sparse recent demand or that purchasing entities may tag similar work under related codes within the heating, ventilation, plumbing, or water distribution families.
