UNSPSC 40174707: Stainless steel pipe threaded flange

Pipe threaded flange made of stainless steel

UNSPSC 40174707 Stainless steel pipe threaded flange is a Commodity code that captures specialized piping components used in infrastructure rehabilitation and wastewater treatment projects. State and local governments procure stainless steel pipe flanges as part of broader sanitary sewer system upgrades, water conveyance repairs, and industrial utility installations where corrosion resistance and durability justify the material premium. The work typically appears embedded within larger construction or infrastructure replacement programs rather than as standalone supply contracts—flanges and fittings serve as components within mainline pipe replacement, service connection work, or system extension projects. County sanitation districts and county departments of public works represent the primary issuing bodies under this code, with occasional activity from municipal water and wastewater utilities.

Recent activity in this code concentrates in California, driven by aging sanitary sewer infrastructure rehabilitation across the state. Santa Clara County has posted at least two material infrastructure solicitations in 2026: County Sanitation District No. 2-3 issued an ITB (ITBRDAFY270088) on August 26, 2026 for the Structural Defect Repair Project Phase 2, due September 17, 2026, which included removal and replacement of vitrified clay and cast iron pipes with PVC and HDPE segments alongside service connection fittings and wyes; separately, Santa Clara County solicited an ITB (ITBRDAFY260694) on April 29, 2026 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, due May 21, 2026, encompassing pavement recycling, asphalt overlay, concrete curb and gutter work, and related roadway improvements. The Sanitation District No. 2-3 project required completion in sixty-five working days from Notice to Proceed and called for physical bid submission at the County Government Center in San Jose. While the posted opportunities emphasize PVC and HDPE for mainline work, stainless steel flanges typically appear in supplemental or specialized connection requirements within these broader rehabilitation scopes that are not itemized separately in the public summaries.
