UNSPSC 40171906: Aluminum pipe reserve flange

Aluminum flange ideal for bathrooms because it does not rust with water vapor or in tropical climates.

UNSPSC 40171906 Aluminum pipe reserve flange is a Commodity code that covers specialized pipe fittings and flanged components for infrastructure rehabilitation. State and local governments buy these components primarily as part of sewer system reconstruction and water infrastructure projects where existing pipe systems require replacement or repair. The issuing bodies under this code include county sanitation districts and county transportation or public works departments that oversee major utility infrastructure upgrades in unincorporated areas and along regional corridors.

Recent activity centers in California, specifically Santa Clara County, where two major infrastructure rehabilitation projects solicited bids in 2026. County Sanitation District No. 2-3 posted an IFB on August 26, 2026 (ITBRDAFY270088) for the Structural Defect Repair Project Phase 2, due September 17, 2026, which involves thirty-five sanitary sewer mainline point repairs and five pipe-burst replacements requiring removal and replacement of vitrified clay pipe with PVC and HDPE pipe, along with service connection fittings including wyes in multiple diameters. Santa Clara County also posted an IFB on April 29, 2026 (ITBRDAFY260694) for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, due May 21, 2026, comprising pavement rehabilitation, curb and gutter work, and related improvements. While the recent opportunities show limited direct sourcing of aluminum pipe reserve flanges, the code appears most relevant to contractors bidding comprehensive sewer and utility infrastructure projects where specialized pipe fittings are components of larger rehabilitation scopes.
