UNSPSC 40173703: Ductile iron pipe reducing flange

Pipe reducing flange made of ductile iron

UNSPSC 40173703 Ductile iron pipe reducing flange is a Commodity code covering flanged pipe fittings and mechanical joint restraining devices for water and wastewater infrastructure. State and local water utilities, county public works departments, and municipal water services departments are the primary buyers; the solicitations show activity from specialized water procurement units within larger municipalities as well as county-level infrastructure authorities. The work includes the supply and delivery of ductile iron and cast iron flanged fittings in multiple sizes and configurations, mechanical joint restraining devices rated for ductile iron pipe, and related accessory packages (gaskets, bolts, nuts). Solicitations typically require conformance to AWWA, ASTM, and ANSI standards, NSF certification for potable water components, firm fixed unit pricing, and delivery within 10 to 30 days of order.

Recent activity spans California, Florida, and Arizona. Palm Beach County Board of County Commissioners issued IFB #26-038/RR in April 2026 (due June 4, 2026) for mechanical joint restraining devices for ductile iron pipe in sizes 3 to 54 inches and polyvinyl chloride pipe, with estimated quantities of 918 and 912 units respectively across two lots and an anticipated contract value of $200,000 over twelve months; the procurement includes SBE price preference (ten percent if within ten percent of lowest non-SBE bid) and five percent local preference for Palm Beach County vendors. The City of Phoenix Water Services Department solicited water pipe and miscellaneous fittings under IFB 260217 (due February 19, 2026) for a five-year contract covering 15 product groups including flanges, reducers, and elbows; the procurement requires five years of prior operation, local inventory availability, next-day delivery on captive parts, and compliance with DBE requirements. Santa Clara County issued ITB ITBRDAFY260694 for the Central Expressway Pavement Rehabilitation Project (due May 21, 2026), which includes removal and replacement of inductive traffic loops and other water-adjacent infrastructure but represents tangential rather than primary pipe-fitting demand under this code. The City of Tampa's RFQ 26-P-00152 (due February 25, 2026) targeted Standard Class 125 flanged fittings in five line items, with SLBE preference and one-year term awards.
