UNSPSC 31351500: Bolted tube assemblies

UNSPSC 31351500 Bolted tube assemblies is a Class code representing fabricated metal tubing components with bolted connections that state and local governments procure for infrastructure maintenance, equipment repair, and facility operations. The code covers pre-assembled or field-assemblable tube structures joined by bolts rather than welding, commonly used in HVAC systems, water distribution networks, compressed air lines, and structural support applications across municipal and county facilities. Issuing bodies typically include county public works departments, city water utilities, school district maintenance operations, and municipal transit authorities that maintain aging infrastructure and equipment requiring replacement or repair of piping and tubing systems.

No recent state and local contract opportunities appear in the available records for this code. The sparse activity under UNSPSC 31351500 suggests limited procurement volume or infrequent solicitation cycles for bolted tube assemblies at the state and local level, which is consistent with the specialized and project-driven nature of this commodity. Firms pursuing this code should monitor regional water utility, public works, and facilities management RFPs and IFBs where infrastructure renewal or equipment overhaul projects are announced, as these tend to surface demand for fabricated metal tubing in concentrated geographic regions rather than as standing or recurring buys.
