UNSPSC 40181808: Furnace tube

A tube furnace is an electric heating device used to conduct syntheses and purifications of inorganic compounds and occasionally in organic synthesis.

UNSPSC 40181808 Furnace tube (Commodity) covers replacement and new furnace tubing for industrial heating and combustion equipment used by state and local facilities. State and local procurement under this code includes supply and installation of boiler tubes, combustion chamber liners, heat exchanger tubing, and related tubular components for institutional and municipal heating plants, power generation facilities, and large institutional campuses. Issuing bodies include state facilities management departments, municipal utilities, county maintenance operations, and independent school districts that maintain central heating plants and steam distribution systems. Work solicited ranges from routine tube replacement during equipment maintenance cycles to full tube bundle assemblies for furnace refurbishment and efficiency upgrades.

The source provides no posted opportunities under this code as of 2026-10-20. Without recent solicitation activity in the dataset, the geographic distribution and representative issuers cannot be characterized. A review of current state and local procurement channels and cooperative purchasing platforms will establish whether this Commodity tier code sees active demand or reflects less-frequent capital and maintenance projects at the jurisdictions that operate large-scale furnace systems.
