UNSPSC 40174007: Copper pipe slipon flange

Slipon flange made of copper

UNSPSC 40174007 Copper pipe slip-on flange, a Commodity code, represents specialized pipe connection fittings used in sanitary sewer infrastructure projects. State and local governments procure these fittings as components within larger sewer mainline rehabilitation, replacement, and extension programs. The code shows activity from special-purpose sanitation districts and county transportation departments executing infrastructure repair and modernization work. Copper slip-on flanges appear in the bill of materials for sewer gravity main construction and rehabilitation, where they join existing and new pipe segments in point repairs, pipe-burst replacements, and mainline extensions. Work solicited under this code involves coordination with other pipe materials (vitrified clay pipe removal, PVC SDR26 replacement, HDPE pipe bursting) and associated fittings such as wyes and service connection laterals.

Santa Clara County, through its County Sanitation District No. 2-3 and county transportation office, represents the dominant recent buyer. On August 26, 2026, County Sanitation District No. 2-3 posted ITB ITBRDAFY270088, Structural Defect Repair Project Phase 2, due September 17, 2026, soliciting bids for thirty-five sanitary sewer mainline point repairs, five mainline pipe-burst replacements at seventeen locations, and two sewer mainline extensions across unincorporated eastern foothills, with completion required in sixty-five working days from Notice to Proceed. A second opportunity, ITB ITBRDAFY260694 posted April 29, 2026 by Santa Clara County for Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard (due May 21, 2026), encompasses comprehensive pavement rehabilitation including concrete curb, gutter, and sidewalk work but does not explicitly list pipe flanges in the posted scope summaries. Recent activity concentrates in Santa Clara County, California. The Sanitation District project is the primary relevant solicitation under this code.
