UNSPSC 31311205: Low alloy steel riveted pipe assemblies

UNSPSC 31311205 Low alloy steel riveted pipe assemblies is a Commodity code that does not align with the recent state and local procurement activity tagged under it. The opportunities shown span industrial pipe supply (HDPE and PVC), stormwater and water system infrastructure, mobile welding services, bridge replacement, and waste-to-energy facility development — none of which involve low alloy steel riveted pipe assemblies as a primary procurement item. The code shows minimal relevant recent activity; a mismatch between the code's nominal scope and actual purchasing patterns suggests this category is either underutilized or miscoded in the jurisdictions' taxonomy.

The tagged opportunities reflect broad infrastructure and facility maintenance work across multiple issuing bodies including city public works departments (Phoenix), counties (Orange, Hillsborough, Broward, Santa Clara), special-purpose authorities (Solid Waste Authority of Palm Beach County, Notla Water Authority), and state agencies (Texas Parks and Wildlife Department, State of California). Representative recent solicitations include the City of Phoenix Public Works Department IFB 27-SW-0447 for industrial pipe, miscellaneous fittings, and equipment (response date September 30, 2026), the City of Augusta Georgia ITB 27-116 for HDPE pipe, couplings, and end sections (September 29, 2026), and Hillsborough County Board of County Commissioners ITB-26-00389 for mobile welding services (September 16, 2026). Geographic spread covers Arizona, Georgia, Florida, California, and Texas. Bidders pursuing this code should verify actual commodity specificity with each issuing body prior to pursuit, as the code descriptor does not reflect the range of modern polymer piping, welding, and infrastructure materials that dominate current state and local procurement under this classification.
