UNSPSC 40174003: Cast iron pipe slipon flange

Pipe slipon flange made of cast iron

UNSPSC 40174003 Cast iron pipe slip-on flange is a Commodity code covering flanged cast iron pipe fittings and related joint restraint devices for water distribution, wastewater, and surface drainage infrastructure. State and local governments buy these components as part of larger water and utility infrastructure programs — capital replacement, rehabilitation, and new construction for municipal water systems, county drainage districts, and transit or special-purpose utility authorities. The sourcing reflects both routine supply-chain procurement (purchase-and-delivery term contracts for inventory stocking) and embedded demand within larger infrastructure projects where flanged fittings are specified components of comprehensive pavement, roadway, or utility work.

Recent activity spans California and Florida. Santa Clara County, California posted an IFB in April 2026 for the Central Expressway Pavement Rehabilitation Project (due May 21, 2026), a comprehensive roadway rehabilitation including pavement, drainage, and infrastructure improvements where flanged pipe components are incidental to the overall scope. Palm Beach County, Florida issued an IFB in April 2026 (due June 4, 2026) for mechanical joint restraining devices on a term contract — specifically solid design restraint devices for ductile iron pipe and polyvinyl chloride (PVC) pipe, with estimated quantities of 918 and 912 units respectively, initial contract value of $200,000 over twelve months, and availability of Small Business Enterprise price preference. The City of Tampa issued an RFQ in March 2026 (due February 25, 2026) for Standard Class 125 cast iron flanged fittings in five line items, including flanged outlet flanges, reducers, and tees, with one-year term and SLBE certification available. The City of Phoenix Water Services Department posted an IFB in February 2026 (due February 19, 2026) for water pipe and miscellaneous fittings including flanges as part of a five-year supply contract with 15 product groups and annual pricing adjustments subject to City approval.
