UNSPSC 40173404: Ductile iron pipe plate flange

Pipe plate flange made of ductile iron

UNSPSC 40173404 Ductile iron pipe plate flange, a Commodity code, represents flanged connection components and related restraining devices that state and local water utilities and transportation agencies buy to support distribution infrastructure, pavement rehabilitation, and water main construction and maintenance. Water utilities procure ductile iron pipe (DIP) flanges, mechanical joint restraining devices for DIP and polyvinyl chloride (PVC) pipe, and flanged fittings as part of routine pipe system assembly, replacement, and repair work. Transportation departments and counties source these components as part of larger pavement and drainage rehabilitation projects. Recent solicitations show a mix of outright purchase orders for individual fittings and term supply contracts for anticipated annual or multi-year volumes. Issuing bodies include county transportation departments (Santa Clara County), county water or utilities authorities (Palm Beach County), municipal water departments (City of Phoenix Water Services), and city procurement offices supporting multiple departments (City of Tampa).

Santa Clara County issued an IFB (ITB 260694) in April 2026 due May 21, 2026, for the Central Expressway Pavement Rehabilitation Project, which included removal and replacement of inductive traffic loops and other components typical of integrated corridor work; the scope is broad infrastructure rehabilitation rather than pipe flange procurement alone, and the code assignment appears incidental to the overall project. Palm Beach County issued a more targeted IFB (#26-038/RR, due June 4, 2026) for mechanical joint restraining devices for DIP (3 to 54 inches) and PVC pipe (3 to 24 inches), with estimated quantities of 918 and 912 units respectively across an anticipated $200,000 contract value over twelve months. The City of Phoenix Water Services Department issued an IFB (260217) for a five-year water pipe and miscellaneous fittings supply contract commencing May 1, 2026, with fifteen product groups including flanges; bidders must have five years' experience, maintain local inventory, and offer next-day delivery on captive parts. The City of Tampa issued an RFQ (26-P-00152, due February 25, 2026) for five line items of cast iron flanged fittings in various sizes and configurations to support city departments. Activity concentrates in California and Florida, with secondary presence in Arizona; the geographic spread is narrow and recent.
