UNSPSC 40174703: Cast iron pipe threaded flange

Pipe threaded flange made of cast iron

UNSPSC 40174703 Cast iron pipe threaded flange, a Commodity code, covers specialized pipe fittings and components used in sanitary sewer infrastructure rehabilitation and replacement projects across state and local water and sanitation districts. State and local governments procure these fittings as part of larger sewer mainline repair, rehabilitation, and extension programs—typically bundled with labor, equipment, and complementary piping materials in competitive-bid infrastructure contracts. The issuing bodies pursuing work under this code are primarily special-purpose sanitation districts and county public works departments managing wastewater collection systems.

Santa Clara County, California, represents the primary recent activity, with two competitive-bid solicitations posted in 2026. County Sanitation District No. 2-3 issued ITB ITBRDAFY270088 on August 26, 2026 (due September 17, 2026) for Structural Defect Repair Project Phase 2, which includes removal and replacement of vitrified clay pipe with new polyvinyl chloride and high-density polyethylene pipe, along with service connection fittings including twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes—components aligned with this commodity code's scope. Santa Clara County also posted ITB ITBRDAFY260694 on April 29, 2026 (due May 21, 2026) for the Central Expressway Pavement Rehabilitation Project, a broader civil infrastructure effort that does not directly reference cast iron pipe fittings in its stated scope. The recent-opportunities block does not support activity outside California or repeat buyers beyond Santa Clara County.
