UNSPSC 40142707: Alloy/Stainless steel cladded flange

Alloy or stainless steel cladded flanges are a type of flange that has a layer of stainless or alloy steel cladding on its surface.

Flange with all types of facing raised, flat face, ring type joint made of alloy steel /Stainless steel including cladded.

UNSPSC 40142707 Alloy/Stainless steel cladded flange is a Commodity code that, based on recent state and local solicitations, does not map clearly to the work actually being procured. The recent opportunities tagged under this code consist of diesel welder/generators, ready-mix concrete delivery services, manhole covers and grates, steel risers, and manhole inlet/outlet infrastructure components — none of which involve alloy or stainless steel cladded flanges as a primary procurement object. The issuing bodies include water districts, cities, counties, and cooperative purchasing vehicles, with no standout repeat buyer across the sample. This code shows a significant mismatch between its nominal scope and the infrastructure and utility-service work that state and local procurement offices are actually tagging and posting under it.

The geographic spread of recent activity touches Texas (North Texas Municipal Water District, City of O'Donnell via Purchasing Cooperative of America), Michigan (City of Jackson), Florida (Pasco County), and Georgia (Gwinnett County Department of Water Resources). Representative recent opportunities include Pasco County Board of County Commissioners' IFB-KM-26-068 for manhole covers and grates posted April 2, 2026, with a bid deadline of May 5, 2026; Gwinnett County Department of Financial Services' IWQ 128258 for steel risers (100 risers with 1-inch set screws and 100 with 2-inch set screws) posted March 30, 2026, with quotations due April 2, 2026; and Purchasing Cooperative of America's RFP OD-437-26 for manhole inlet, outlet, and related items on behalf of PCA members nationwide, posted January 22, 2026, with proposals due February 24, 2026. Given the consistent tagging disconnect, firms pursuing work in water utility infrastructure, manhole rehabilitation, or sewer services may find broader success searching adjacent UNSPSC codes in the utility and water-infrastructure family rather than relying on this Commodity code's actual posting activity.
