UNSPSC 40173401: Brass pipe plate flange

Pipe plate flange made of brass

UNSPSC 40173401 Brass pipe plate flange, a Commodity code, nominally covers metal pipe fittings and flanges used in industrial piping systems. Recent state and local solicitations tagged under this code, however, show activity concentrated in municipal water and wastewater infrastructure — specifically sanitary sewer rehabilitation and mainline replacement projects. The actual procurement under this code spans pipe fittings, connection wyes, and related components used in sewer system point repairs, pipe-burst replacements, and mainline extensions. County sanitation districts and county public works departments are the primary issuing bodies, soliciting through invitation-to-bid (ITB) notices with response windows typically two to three weeks.

Santa Clara County dominates recent activity, posting two major infrastructure ITBs in the first nine months of 2026. County Sanitation District No. 2-3 issued ITB ITBRDAFY270088 on August 26, 2026, due September 17, 2026, for the Structural Defect Repair Project Phase 2 — a sewer rehabilitation program in unincorporated eastern foothills involving thirty-five point repairs, five pipe-burst replacements, and two mainline extensions, with scope including removal and replacement of service connection wyes (4"×6", 4"×8", 4"×10") alongside PVC and HDPE pipe. Santa Clara County issued ITB ITBRDAFY260694 on April 29, 2026, due May 21, 2026, for the Central Expressway Pavement Rehabilitation Project, which included pavement work but fell outside the scope of this pipe-fitting code. The code shows narrow recent opportunity volume concentrated in California municipal infrastructure projects.
