UNSPSC 40171905: Copper pipe backup flange

Pipe backup flange made of copper

UNSPSC 40171905 Copper pipe backup flange is a Commodity code that encompasses specialized plumbing and piping fittings used in sanitary sewer infrastructure rehabilitation and mainline extension projects. State and local governments acquire these components as part of comprehensive sewer system repairs, pipe replacements, and service connection upgrades. The recent opportunities show that sanitation districts and county public works departments procure copper pipe backup flanges and related fittings (such as wyes and connection components) during point-repair programs, pipe-burst replacement initiatives, and mainline extensions that involve removal and replacement of aging vitrified clay pipe, cast iron, and related infrastructure with modern PVC, HDPE, and precast concrete systems.

Santa Clara County has emerged as a active buyer in this code space, with two recent ITB solicitations from the County and the County Sanitation District. The Sanitation District No. 2-3 Structural Defect Repair Project Phase 2 (ITB ITBRDAFY270088, due September 17, 2026) encompasses thirty-five sanitary sewer mainline point repairs and five pipe-burst replacements requiring removal and replacement of service connection fittings, including twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes, along with multiple lengths of PVC and HDPE pipe and precast concrete manholes. The Central Expressway Pavement Rehabilitation Project (ITB ITBRDAFY260694, due May 21, 2026) addresses pavement rehabilitation and related improvements but does not specify copper pipe backup flanges in the available scope description. Activity is concentrated in California, specifically the unincorporated areas and municipalities within Santa Clara County's jurisdiction, with work completion requirements of sixty-five to 142 working days from notice to proceed.
