UNSPSC 40174000: Pipe slipon flanges

UNSPSC 40174000 Pipe slip-on flanges, a Class code, encompasses flanged pipe connectors and fittings used in municipal water, wastewater, and stormwater infrastructure projects. State and local procurement under this code centers on sanitary sewer rehabilitation, mainline extensions, and related piping infrastructure repair work. The issuing bodies soliciting under the code include county sanitation districts and county public works departments managing large-scale utility infrastructure projects. The work being purchased reflects replacement and extension of aging sewer systems using modern piping materials and connection fittings integrated with concrete manholes, service laterals, and system extensions in unincorporated areas and along major corridors.

Santa Clara County represents the primary recent activity for this code. 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, covering thirty-five sanitary sewer mainline point repairs, five pipe-burst replacements at seventeen locations, and two mainline extensions in the unincorporated eastern foothills. The scope includes removal and replacement of vitrified clay pipe with PVC SDR26 at multiple diameters totaling approximately 483 linear feet, pipe bursting with 1,080 linear feet of 6-inch HDPE, and service connection fittings including twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes, with work completion required in sixty-five working days from Notice to Proceed. A second Santa Clara County ITB (ITBRDAFY260694), posted April 29, 2026 and due May 21, 2026, for Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, included pavement, curb, sidewalk, and traffic infrastructure work but does not reflect activity directly under the pipe-flange code scope. Bidders must submit physical proposals to the County Government Center in San Jose; electronic bids are not accepted.
