UNSPSC 40173403: Cast iron pipe plate flange

Pipe plate flange made of cast iron

UNSPSC 40173403 Cast iron pipe plate flange is a Commodity code under which state and local water utilities and public works departments procure cast iron and ductile iron pipe fittings, flanges, and mechanical joint restraining devices for water distribution, wastewater, and stormwater infrastructure. The code captures flanged fittings in standard configurations—reducers, tees, outlet flanges, and gate valves—along with mechanical joint restraining devices (solid design and solid ring design) for pipe ranging from 3 inches to 54 inches in diameter, all meeting American Water Works Association, ASTM, and ANSI standards including NSF potable-water certification. Cities, counties, and regional water authorities issue the solicitations, typically as term contracts with firm unit pricing and multi-year renewal options. Issuing bodies include the City of Tampa (Hillsborough County), City of Phoenix Water Services Department, Palm Beach County Board of County Commissioners, and Santa Clara County; Tampa and Palm Beach County have posted multiple recent opportunities in the water-infrastructure commodity space, signaling sustained demand from Florida jurisdictions.

Recent activity spans California, Florida, and Arizona. The City of Phoenix Water Services Department issued IFB 260217 on February 23, 2026, for a five-year water pipe and miscellaneous fittings contract commencing May 1, 2026, with sealed offers due February 19, 2026, covering 15 product groups and spanning flanges, reducers, gate valves, and related components. Palm Beach County Board of County Commissioners issued IFB 26-038/RR on April 22, 2026, for mechanical joint restraining devices on a term contract basis, with separate lots for ductile iron pipe (918 units across twelve sizes) and PVC pipe (912 units across ten sizes), bids due June 4, 2026, and anticipated contract value of $200,000 over the initial twelve-month term. The City of Tampa issued RFQ 26-P-00152 on March 9, 2026, for Standard Class 125 Flanged Fittings (six line items including 6-inch by 2-inch flanged outlet flanges and reducers), quotes due February 25, 2026, for a one-year award period. Palm Beach County offers a ten percent price preference for Small Business Enterprise bidders and a five percent local preference for bidders with a permanent place of business in the county, while the City of Phoenix imposes DBE compliance under 49 C.F.R. Part 26.
