UNSPSC 40173707: PVC plastic pipe reducing flange

Pipe reducing flange made of PVC plastic

UNSPSC 40173707 PVC plastic pipe reducing flange is a Commodity code under which state and local governments procure component fittings and flanges for polyvinyl chloride (PVC) pipe systems used in water, wastewater, and stormwater infrastructure. The recent state and local activity shows demand for PVC reducing flanges and associated wye fittings as part of larger sanitary sewer rehabilitation and infrastructure extension projects. Issuing bodies soliciting under this code include county sanitation districts and county public works departments undertaking utility infrastructure rehabilitation. The procurement pattern reflects replacement of aging vitrified clay pipe (VCP) and cast iron systems with modern PVC piping, where reducing flanges and wye fittings connect different pipe diameters and serve branch connections.

Recent opportunities in California demonstrate the code's application. Santa Clara County Sanitation District No. 2-3 posted an IFB (ITBRDAFY270088) on August 26, 2026 for the Structural Defect Repair Project Phase 2, due September 17, 2026, which calls for removal and replacement of service connection fittings including twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes as part of a sewer mainline rehabilitation program in the unincorporated eastern foothills. Santa Clara County also posted an earlier pavement rehabilitation IFB (ITBRDAFY260694) on April 29, 2026 due May 21, 2026 for Central Expressway between Bowers Avenue and Scott Boulevard, though that solicitation emphasizes roadway rather than utility component procurement. The code sees activity concentrated in California, with Santa Clara County appearing as a repeat buyer of infrastructure rehabilitation work. Contractors pursuing this code should monitor sanitation district and county public works procurement offices for sewer system overhauls and utility infrastructure extensions where PVC component replacement is a bundled requirement.
