UNSPSC 40174107: HDPE plastic pipe socketweld flange

Pipe socketweld flange made of HDPE plastic

UNSPSC 40174107 HDPE plastic pipe socketweld flange is a Commodity code that captures high-density polyethylene pipe and related fittings used in municipal wastewater and stormwater infrastructure rehabilitation. State and local governments procure HDPE pipe primarily as a replacement or extension material in sanitary sewer mainline repair and rehabilitation projects, where it is installed via pipe bursting or traditional open-cut methods to replace aging vitrified clay pipe, cast iron, or asbestos cement systems. The code also encompasses socketweld flanges and service connection wyes used to tie in lateral lines and connect existing infrastructure during mainline upgrades. Issuing bodies soliciting under this code include county sanitation districts and county public works departments managing regional infrastructure systems.

Recent activity centers in California, particularly Santa Clara County. County Sanitation District No. 2-3 posted ITB ITBRDAFY270088 on August 26, 2026, due September 17, 2026, for the Structural Defect Repair Project Phase 2, which calls for 1,080 linear feet of 6-inch HDPE pipe for pipe bursting operations within unincorporated eastern foothills, along with PVC mainline segments and twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes for service connection replacement. Santa Clara County also posted ITB ITBRDAFY260694 on April 29, 2026, due May 21, 2026, for the Central Expressway Pavement Rehabilitation Project, which involves broader roadway work and did not explicitly reference HDPE pipe quantities in the posted summary, though such materials may be included in the full specifications. Both solicitations used physical bid submission at the County Government Center in San Jose, with sixty-five to one hundred forty-two working day completion windows.
