UNSPSC 40181807: Finned tube

Finned tubes are the main components of heat exchangers. They are a series of tubes where fins have been added on the outside to increase the contact area with the outside fluid, to exchange heat and between the fluid inside the tube and the fluid outside the tube.

UNSPSC 40181807 Finned tube is a Commodity code that covers replacement tubing and tube assemblies for water and wastewater treatment equipment, as demonstrated by recent state and local solicitations purchasing pump tubing for sampler units and rehabilitation components for municipal infrastructure projects. State and local governments procure replacement tubes and tubing assemblies for operational and capital infrastructure work, particularly in water resources management and transportation rehabilitation. The issuing bodies soliciting under this code include county water departments and county transportation authorities, reflecting the infrastructure-maintenance nature of the purchases.

Recent activity includes a Gwinnett County Department of Water Resources quotation request (RFQ) posted June 25, 2026, due June 30, 2026, for 400 units of pump tubing (manufacturer item 60-6700-062 or approved equivalent) in packs of five for 5800/4700 and 6700 Series Avalanche Sampler equipment, with FOB Destination delivery to the Central Facility in Lawrenceville, Georgia, and a Santa Clara County invitation to bid (ITB) posted April 29, 2026, due May 21, 2026, for the Central Expressway Pavement Rehabilitation Project, which includes removal and replacement of components alongside extensive pavement and infrastructure work. Georgia and California represent the primary jurisdictions with identifiable recent opportunities under this code.
