UNSPSC 31311309: Stainless steel bolted pipe assemblies

UNSPSC 31311309 Stainless steel bolted pipe assemblies (Commodity) does not appear to align with the recent state and local procurement activity tagged under this code. The opportunities currently solicited show minimal direct correlation to stainless steel bolted assemblies; instead, they reflect broader industrial pipe, materials, and construction procurement spanning multiple pipe types, metals, water systems, and site work.

The issuing bodies reflect the typical cross-section of state and local water infrastructure procurement: the State of California (materials and metals), county water authorities (Gwinnett County, Orange County, Notla Water Authority), city public works departments and utilities (Phoenix, Lawrenceville, Lavonia, Palm Bay, Tucson), regional transportation authorities, and educational institutions (University of Wisconsin-Madison). Geographic concentration appears heaviest in Florida (Orange County, Palm Bay) and Georgia (Gwinnett County, Lawrenceville, Lavonia, Notla Water Authority), with secondary activity in California, Arizona, Colorado, and Wisconsin. Recent solicitations under this code span water system improvements, stormwater and sewer pipe replacement, industrial pipe and fittings supply contracts, metals procurement, and specialized welding and fabrication services. Representative opportunities include the City of Phoenix Public Works Department IFB 26-SW-0379 for industrial pipe, fittings, and equipment (response due August 12, 2026) covering HDPE and PVC pipe on a three-year supply contract; Gwinnett County Board of Commissioners ITB BL079-26 for stormwater pipe on annual contract (response due May 19, 2026) covering reinforced concrete, HDPE, and corrugated metal pipe; and Orange County, Florida IFB Y26-126 for sewer pipes and fittings (response due January 22, 2026) with an estimated five-year spending total of $28.7 million. The code appears to capture water and wastewater infrastructure materials and related services more broadly than stainless steel assemblies specifically, suggesting either inconsistent code assignment in source materials or declining activity in the narrow commodity itself.
