UNSPSC 40173405: Malleable iron pipe plate flange

Pipe plate flange made of malleable iron

UNSPSC 40173405 Malleable iron pipe plate flange (Commodity) encompasses fittings and flanged components used in water and wastewater infrastructure repair and installation. State and local buyers procure these components as part of sewer rehabilitation, pipe replacement, and mainline extension projects. The code applies to discrete pipe fittings, flanged connectors, and related structural components sourced as materials within larger infrastructure rehabilitation contracts. Sanitation districts and county public works departments are the primary issuing bodies, typically bundling these components into broader sewer infrastructure improvement solicitations alongside labor, equipment, and related materials.

Santa Clara County's sanitation and public works divisions dominate recent activity under this code. County Sanitation District No. 2-3 issued an ITB (Solicitation Number ITBRDAFY270088) on August 26, 2026 with a response deadline of September 17, 2026 for the Structural Defect Repair Project Phase 2, a sewer rehabilitation program in the unincorporated eastern foothills that includes removal and replacement of service connection fittings—specifically twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes—alongside mainline pipe replacement in multiple diameters (6-inch, 8-inch, and 10-inch PVC and HDPE). Santa Clara County also issued an ITB (Solicitation Number ITBRDAFY260694) on April 29, 2026 with a May 21, 2026 deadline for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, though that solicitation focused on roadway and traffic infrastructure rather than wastewater components. The recent opportunities signal active sewer infrastructure rehabilitation spending in California's Bay Area, with work completion timelines of sixty-five to 142 working days from notice to proceed.
