UNSPSC 31311602: Carbon steel sonic welded pipe assemblies

UNSPSC 31311602 Carbon steel sonic welded pipe assemblies (Commodity) does not align with actual recent state and local procurement activity under this code. The nine posted opportunities span industrial piping supply, welding services, stormwater and water system infrastructure, bridge replacement, waste-to-energy facility design-build, and pavement rehabilitation—none of which involve carbon steel sonic welded pipe assemblies as a discrete product line. The mismatch reflects either miscoding by issuing bodies or database-level classification drift; the code sees minimal relevant solicitation activity.

State and local buyers posting opportunities under or near this code include city public works departments (Phoenix, Palm Bay, Lawrenceville), county governments (Hillsborough, Orange, Santa Clara), special-purpose water authorities (Notla Water Authority), and Florida county solid-waste agencies. Recent opportunities cluster in Florida, Georgia, and California. Representative recent solicitations include the City of Phoenix Public Works' IFB27SW0447 (September 2026) for industrial pipe and fittings supply on an as-needed basis with a three-year term and two one-year options; the Hillsborough County Board of County Commissioners' ITB-26-00389 (September 2026) for mobile welding services estimated at $207,429.10 across three years at solid-waste facilities; and the City of Augusta, Georgia's ITB 27-116 (September 2026) for HDPE pipe, couplings, and end sections for drainage installation. Buyers in this space emphasize local inventory maintenance, rapid delivery (24–48 hours standard, four-hour response for emergency services), DBE compliance on federally assisted projects, and firm fixed pricing across multi-year terms. No solicitations explicitly request carbon steel sonic welded pipe assemblies; consider this code for watch status pending clarification of actual commodity definitions or shift in issuing-body tagging.
