UNSPSC 40174711: HDPE plastic pipe threaded flange

Pipe threaded flange made of HDPE plastic

UNSPSC 40174711 HDPE plastic pipe threaded flange is a Commodity code covering high-density polyethylene pipe and associated fittings used in sanitary sewer rehabilitation and infrastructure replacement work. State and local governments procure this material as part of broader sewer mainline repair, pipe-burst replacement, and sewer extension projects. Recent solicitations show sanitation districts and county public works departments as the primary issuing bodies, with work scoped as removal-and-replacement of aging clay and cast-iron pipe using HDPE pipe bursting and conventional excavation-and-replacement methods. Service connection fittings—including wyes and other junction components—are specified alongside the mainline pipe stock.

Santa Clara County sanitation and public works agencies have posted the most recent activity under this code. The County Sanitation District No. 2-3 Structural Defect Repair Project Phase 2 (ITB ITBRDAFY270088, due September 17, 2026) called for 1,080 linear feet of 6-inch HDPE pipe for mainline pipe bursting, along with PVC replacement pipe and service-connection wyes, as part of a sixty-five working day sewer rehabilitation program in unincorporated eastern foothills. A second Santa Clara County opportunity, the Central Expressway Pavement Rehabilitation Project Between Bowers Avenue and Scott Boulevard (ITB ITBRDAFY260694, due May 21, 2026), encompassed pavement and drainage work but did not explicitly reference HDPE pipe in the posted scope. The code shows limited recent activity; the primary signal is infrastructure rehabilitation work in California, driven by aging sewer systems and county-level capital projects.
