UNSPSC 31163020: Flange coupling

A type of coupling having two separate cast iron flanges. Each flange is mounted on the shaft end and keyed to it.

UNSPSC 31163020 Flange coupling is a Commodity code that nominally describes mechanical shaft connectors, but the single recent state and local solicitation tagged under this code does not reflect procurement of coupling hardware. DeKalb County's June 2026 ITB for reconstruction of the DeKalb Tennis Center in Mason Mill Park, Decatur, Georgia centers on information technology and low-voltage infrastructure installation — conduit, cabling, raceways, terminations, and testing — rather than mechanical couplings. The mismatch suggests either a coding error in the county's procurement system or a narrow subset of the larger project scope that involves coupling components. No other recent state and local opportunities appear under this code in the source material.

The single identified opportunity is DeKalb County's ITB 2026-076-ITB, posted June 9, 2026, with bids due July 13, 2026. Work scope includes furnishing and installing IT and low-voltage infrastructure systems for the tennis center's new pro shop building in accordance with DeKalb County Department of Innovation and Technology standards, including labor, materials, equipment, supervision, testing, certifications, and documentation. The limited activity and categorical mismatch make this code difficult to assess for business development purposes — prospective bidders should verify the actual commodity or service category before pursuing this or similar opportunities tagged as 31163020.
