UNSPSC 40173702: Cast iron pipe reducing flange

Pipe reducing flange made of cast iron

UNSPSC 40173702 Cast iron pipe reducing flange is a Commodity code used by state and local water and wastewater utilities, transportation departments, and municipalities to procure cast iron and ductile iron pipe fittings, flanges, and joint restraining devices for water distribution systems, stormwater infrastructure, and pavement rehabilitation projects. The recent solicitations show that state and local governments are buying a range of pipe fittings and accessories — including reducing flanges, tees, elbows, couplings, bushings, gate valves, and mechanical joint restraining devices for both ductile iron pipe (DIP) and polyvinyl chloride (PVC) pipe — typically as supply contracts with firm unit pricing and specified delivery requirements. Issuing bodies include city water utilities (Phoenix Water Services, City of Tampa), county water and transportation departments (Santa Clara County, Palm Beach County), and municipal purchasing departments. The code also captures construction-related procurement for pavement rehabilitation projects that include incidental water infrastructure work, though the primary focus is on utility supply contracts.

Recent opportunities span California, Florida, and Arizona, with notable activity in Florida and the Southwest. The City of Phoenix Water Services issued an IFB in February 2026 for water pipe and miscellaneous fittings (15 product groups including flanges and reducers) for a five-year contract commencing May 1, 2026, with a pre-offer conference and sealed-bid submission by February 19, 2026. Palm Beach County Board of County Commissioners issued an IFB in April 2026 for mechanical joint restraining devices for DIP and PVC pipe in estimated quantities of 918 and 912 units respectively, with an anticipated contract value of $200,000 over twelve months and a June 4, 2026 deadline. The City of Tampa issued an RFQ in March 2026 for Standard Class 125 flanged fittings (five line items including 6-inch by 2-inch flanged outlet flanges and 4-inch by 3-inch reducers) with electronic submission by February 25, 2026, and a one-year award period. Santa Clara County issued an ITB in April 2026 for pavement rehabilitation work including incidental water and drainage infrastructure, with bids due May 21, 2026. Insurance requirements are standard across these procurements ($1 million to $2 million general liability depending on issuing body), and several solicitations include SBE or local business preferences.
