UNSPSC 40173710: HDPE plastic pipe reducing flange

Pipe reducing flange made of HDPE plastic

UNSPSC 40173710 HDPE plastic pipe reducing flange, a Commodity code, represents the supply of high-density polyethylene pipe components and fittings used in water and wastewater infrastructure rehabilitation projects. State and local sanitation districts and county transportation departments solicit under this code for sewer mainline repairs, pipe replacement, and related gravity-fed conveyance work. The specific commodity — HDPE reducing flanges and associated fittings — appears in solicitations for point repairs, pipe-burst replacement, and mainline extensions where existing vitrified clay pipe (VCP) or cast iron infrastructure is being rehabilitated or extended using modern thermoplastic piping systems. Work is typically procured through invitation to bid (ITB) and includes labor, materials, and equipment for removal, installation, and testing.

Santa Clara County has been the primary recent issuing body, with two ITBs posted between April and August 2026. The Sanitation District No. 2-3 Structural Defect Repair Project Phase 2 (ITBRDAFY270088), due September 17, 2026, called for 1,080 linear feet of 6-inch HDPE pipe bursting and removal and replacement of service connection fittings including wyes in multiple sizes for sewer mainline rehabilitation in the unincorporated eastern foothills. The Central Expressway Pavement Rehabilitation Project Between Bowers Avenue and Scott Boulevard (ITBRDAFY260694), due May 21, 2026, focused primarily on pavement work but included related utility modifications. Recent activity is concentrated in California, specifically Santa Clara County, reflecting broader state and regional investment in aging sanitary sewer infrastructure renewal. The code shows limited recent posting volume; firms pursuing this commodity should monitor California county sanitation district and water agency procurement channels for infrastructure rehabilitation cycles.
