UNSPSC 31311202: Carbon steel riveted pipe assemblies

UNSPSC 31311202 Carbon steel riveted pipe assemblies is a Commodity code that captures state and local procurement of metal piping products for water, wastewater, stormwater, and natural gas infrastructure projects. Recent state and local opportunities under this code reflect demand for industrial pipe, fittings, and materials used in municipal utility systems, though the solicitations span a broader scope than riveted assemblies alone—including HDPE, PVC, reinforced concrete pipe, corrugated metal pipe, ductile iron pipe, and associated fittings and valves that support infrastructure repair and replacement work. Issuing bodies include state departments and county governments as well as municipal water and wastewater utilities, with recent activity concentrated among Florida counties (Orange County, Brevard County, and the City of Palm Bay), Georgia municipalities (Gwinnett County, the City of Lawrenceville, and Notla Water Authority), and specialized procurement by Arizona and California jurisdictions. The State of California, the City of Phoenix Public Works Department, and several Florida utilities have posted multiple or recent solicitations for pipe and piping materials, indicating sustained demand from repeat buyers in those regions.

Representative recent opportunities include the State of California's competitive bid for steel materials (RFBIS27200030, due July 29, 2026) with an attached price list and technical specifications document; the City of Phoenix Public Works Department's IFB for industrial pipe, miscellaneous fittings, and equipment on an as-needed basis (IFB 26-SW-0379, due August 12, 2026) covering HDPE and PVC pipe from 0.75 to 24 inches in diameter with firm, fixed pricing for a three-year initial term and two optional one-year extensions; Gwinnett County's annual contract procurement for stormwater pipe including reinforced circular concrete pipe, HDPE, and corrugated metal pipe (BL079-26, due May 19, 2026) with a four-year initial term and four optional 12-month renewals; and the City of Lawrenceville's solicitation for natural gas pipe and materials storage and just-in-time delivery (PE66751NONST2027000000096, due July 23, 2026). Activity concentrates in the Southeast and Southwest; competitive profiles typically emphasize delivery responsiveness (24–48 hours for municipal utilities), firm pricing throughout the contract term, and compliance with American Iron and Steel requirements where federal funding is present.
