UNSPSC 40174703: Cast iron pipe threaded flange

Pipe threaded flange made of cast iron

UNSPSC 40174703 Cast iron pipe threaded flange (Commodity) encompasses cast iron and ductile iron pipe fittings and flanges that state and local water utilities, public works departments, and transit authorities procure for water distribution system maintenance, repair, and expansion. Recent solicitations show demand for both threaded flanges and broader flanged fitting categories — reducers, tees, outlet flanges, and joint restraining devices in sizes ranging from 2 inches to 54 inches — supplied with gaskets, bolts, nuts, and accessory packages. Issuing bodies include municipal water services departments (City of Phoenix, City of Tampa), county water and transportation authorities (Santa Clara County, Palm Beach County), and miscellaneous city departments. Water utilities are the repeat buyers, with Phoenix and Palm Beach County each posting separate procurements within the past four months.

Activity concentrates in Arizona, California, and Florida. Representative recent opportunities include the City of Phoenix Water Services Department's five-year IFB for water pipe and miscellaneous fittings posted February 23, 2026, with sealed offers due February 19, 2026, covering 15 product groups including flanges and requiring AWWA, ASTM, and ANSI/NSF compliance; Palm Beach County Board of County Commissioners' IFB 26-038/RR for mechanical joint restraining devices for ductile iron and PVC pipe posted April 22, 2026, due June 4, 2026, with an anticipated contract value of $200,000 over twelve months and SBE preference available; and the City of Tampa's RFQ 26-P-00152 for Standard Class 125 flanged fittings posted March 9, 2026, due February 25, 2026. Bidders must meet insurance requirements (typically $1 million to $2 million general liability), provide manufacturer warranties, and comply with local SBE preferences and E-Verify requirements. DBE status qualifies under Phoenix's procurement, and SLBE certification triggers preference in Tampa.
