UNSPSC 40173706: Stainless steel pipe reducing flange

Pipe reducing flange made of stainless steel

UNSPSC 40173706 Stainless steel pipe reducing flange is a Commodity code that appears in state and local solicitations primarily for wastewater and sanitary sewer infrastructure projects where PVC, HDPE, and cast iron piping systems require connection fittings, reducers, and flange assemblies during mainline repairs, replacements, and extensions. State and local water districts and county sanitation agencies issue the bulk of procurement activity under this code, typically bundling reducing flanges and wyes as component materials within larger infrastructure rehabilitation IFBs rather than as standalone line items. The scope reflects utility-infrastructure modernization work—pipe-bursting replacements of aging vitrified clay pipe (VCP), mainline extensions in unincorporated service areas, and service connection fitting replacements in 4-inch through 10-inch diameter configurations.

Santa Clara County has been the most active jurisdiction in the recent opportunity set. County Sanitation District No. 2-3 issued ITB ITBRDAFY270088 on August 26, 2026 for the Structural Defect Repair Project Phase 2, due September 17, 2026, which called for removal and replacement of twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes as part of a thirty-five-point-repair and two-mainline-extension program in unincorporated eastern foothills Santa Clara County. Santa Clara County also posted ITB ITBRDAFY260694 on April 29, 2026 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, due May 21, 2026, though that solicitation focused on pavement and traffic infrastructure rather than sanitary sewer fittings. Recent activity is concentrated in California, specifically the San Francisco Bay Area, where aging utility infrastructure and infill development drive repeated rehabilitation procurement cycles.
