UNSPSC 40174704: Ductile iron pipe threaded flange

Pipe threaded flange made of ductile iron

UNSPSC 40174704 Ductile iron pipe threaded flange is a Commodity code that covers specialized pipe fittings and flanged connections used in sanitary sewer infrastructure rehabilitation and water distribution projects. State and local governments procure this code primarily through county sanitation districts, county public works departments, and municipal water and wastewater authorities executing mainline sewer repairs, pipe replacements, and extensions. The scope of work involves removal and replacement of aging pipe infrastructure—particularly vitrified clay pipe (VCP) and cast iron pipe—with modern materials such as PVC and HDPE, along with associated fittings including wyes, service connection fittings, and flanged tee and reducer assemblies that connect mainline and lateral segments.

Recent activity concentrates in California, particularly Santa Clara County. County Sanitation District No. 2-3 in Santa Clara County issued ITB ITBRDAFY270088 on August 26, 2026, for the Structural Defect Repair Project Phase 2, with bids due September 17, 2026, soliciting labor, materials, and equipment for thirty-five sanitary sewer mainline point repairs, five mainline pipe-burst replacements, and two mainline extensions in the unincorporated eastern foothills. The scope includes removal and replacement of service connection fittings—twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes—alongside PVC and HDPE pipe installation. Santa Clara County Department of Transportation also issued ITB ITBRDAFY260694 on April 29, 2026, for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, due May 21, 2026, which included pavement rehabilitation, curb and gutter installation, and related infrastructure improvements. The district requires sixty-five working days for project completion from Notice to Proceed.
