UNSPSC 40171902: Forged steel pipe backup flange

Pipe backup flange made of forged steel

UNSPSC 40171902 Forged steel pipe backup flange is a Commodity code that covers specialized pipe fittings and components used in water and wastewater infrastructure repair and replacement work. State and local governments procure these components as part of larger sanitation and utility district projects involving sewer system rehabilitation, mainline repairs, and pipe replacement. Issuing bodies sourcing under this code include county sanitation districts, county public works departments, and regional water authorities undertaking infrastructure rehabilitation. The work typically involves removal and replacement of deteriorated pipe systems with modern materials, installation of service connection fittings, and related underground utility work.

Santa Clara County leads recent activity under this code, with two substantial infrastructure projects posted in 2026. The County Sanitation District No. 2-3 Structural Defect Repair Project Phase 2 (ITBRDAFY270088), with bids due September 17, 2026, encompasses thirty-five sanitary sewer mainline point repairs and five pipe-burst replacements using PVC and HDPE pipe along with service connection wyes and fittings across the unincorporated eastern foothills. The Central Expressway Pavement Rehabilitation Project Between Bowers Avenue and Scott Boulevard (ITBRDAFY260694), due May 21, 2026, is primarily a roadway project but includes related utility modifications. Both solicitations were issued as ITBs (invitation to bid) with physical bid delivery required to the County Government Center in San Jose. Activity is concentrated in California; no other states appear in the recent opportunity record.
