UNSPSC 40142706: Carbon steel flange

Carbon steel flanges are a type of flange made from carbon steel material. They are commonly used in piping systems for their durability, strength, and resistance to corrosion. They are available in various sizes and shapes, including weld neck, slip-on, threaded, and blind flanges, among others. Flange with all types of facing raised, flat face, ring type joint made of carbonsteel.

UNSPSC 40142706 Carbon steel flange is a Commodity code that nominally addresses pipe and fitting components, but the recent state and local solicitations tagged under it show minimal relevance to the code's stated scope. The opportunities posted instead address welding equipment (Lincoln Frontier 400X welder/generators), ready-mix concrete delivery services, manhole covers and grates, steel manhole risers, and manhole inlet/outlet infrastructure items. These are material handling, infrastructure component, and construction services procurements rather than carbon steel flanges per se. State and local issuing bodies represented in the recent block include a municipal water district (North Texas Municipal Water District), a city public works department (City of Jackson), a county board of commissioners (Pasco County), a county purchasing division (Gwinnett County), and a statewide cooperative purchasing vehicle (Purchasing Cooperative of America). No repeat buyers appear across multiple recent opportunities, and the block shows no clear pattern of jurisdictions sourcing actual carbon steel flanges under this code.

The geographic spread spans Texas (North Texas Municipal Water District, City of Jackson represented through the PCA cooperative, City of O'Donnell), Michigan (City of Jackson), Georgia (Gwinnett County), and Florida (Pasco County), with the PCA cooperative enabling national scope. Representative recent opportunities include Pasco County's Invitation for Bid IFB-KM-26-068 for manhole covers and grates with a bid deadline of May 5, 2026, and Gwinnett County Department of Water Resources' Informal Written Quotation 128258 for steel risers posted March 30, 2026, with quotations due April 2, 2026. The code shows little recent relevant activity — the mismatch between the code's nominal scope (carbon steel flanges) and the actual procurement content (water infrastructure components and equipment unrelated to flanges) suggests misclassification in the source data rather than active state and local demand for the commodity itself.
