UNSPSC 40173406: Stainless steel pipe plate flange

Pipe plate flange made of stainless steel

UNSPSC 40173406 Stainless steel pipe plate flange is a Commodity code that encompasses metallic pipe fittings and flanged components used in water, wastewater, and utility infrastructure projects. State and local procurement under this code centers on repair, replacement, and rehabilitation of sanitary sewer systems, water distribution networks, and related municipal utility infrastructure where corrosion-resistant piping materials are specified. Issuing bodies soliciting under the code include county sanitation districts, county transportation and public works departments, and municipal utilities across multiple jurisdictions. The work reflects a mix of infrastructure rehabilitation (point repairs, mainline replacements, extensions) and new-construction components requiring engineered fittings that meet material and pressure specifications for gravity-flow and pressurized systems.

Recent activity concentrates in California, particularly in Santa Clara County, where two ITB opportunities posted in 2026 illustrate the typical demand pattern. County Sanitation District No. 2–3 posted ITB ITBRDAFY270088 on August 26, 2026 for the Structural Defect Repair Project Phase 2 (response due September 17, 2026), a sewer infrastructure rehabilitation program that called for removal and replacement of vitrified clay pipe with PVC SDR26 at multiple diameters, HDPE pipe-burst replacements, and service connection fittings including 4"×6", 4"×8", and 4"×10" wyes. Santa Clara County posted ITB ITBRDAFY260694 on April 29, 2026 for the Central Expressway Pavement Rehabilitation Project (response due May 21, 2026), which encompassed partial-depth recycling, hot-mix asphalt overlay, PCC curb and gutter installation, and related pavement work. Both opportunities required physical bid submission to the County Clerk of the Board of Supervisors at the County Government Center in San Jose and specified tight completion schedules (65 working days and 142 working days respectively). The code shows active demand from water and wastewater utilities in California, though geographic and issuing-body breadth remains limited in the recent-opportunities record.
