UNSPSC 31311209: Stainless steel riveted pipe assemblies

UNSPSC 31311209 Stainless steel riveted pipe assemblies (Commodity) covers industrial and municipal piping systems that state and local governments purchase for water, wastewater, stormwater, and gas infrastructure projects. Recent solicitations show demand spans water treatment facility upgrades, outfall pipe replacement, sewer systems, natural gas distribution, and stormwater management—with procurement focused on both material supply contracts and construction projects incorporating piping components. The mix of issuing bodies reflects infrastructure-heavy jurisdictions: water authorities, county utilities departments, city public works and water/wastewater services, counties, and special-purpose districts. Repeat buyers in the recent activity include Orange County, Florida (sewer pipes and fittings, stormwater rehabilitation), the City of Phoenix (industrial pipe and fittings supply), Gwinnett County, Georgia (stormwater pipe), and the City of Lavonia, Georgia (water treatment plant improvements).

Geographic concentration is strongest in Florida (Orange County utilities and environmental infrastructure, Palm Bay stormwater and outfall projects, City of Tucson water facilities) and Georgia (Gwinnett County stormwater procurement, Lavonia water treatment, Lawrenceville gas distribution, Notla Water Authority water line upgrades), with secondary activity in Arizona and California. Representative recent solicitations include the City of Phoenix Public Works Department's IFB 26-SW-0379 (July 8, 2026, due August 12, 2026) for industrial pipe, fittings, and equipment on a three-year supply contract with two one-year options; Gwinnett County's ITB BL079-26 (April 16, 2026, due May 19, 2026) for reinforced concrete pipe, HDPE, and corrugated metal pipe on a four-year annual contract; and Orange County, Florida's Y26-126 (updated due date January 22, 2026) for sewer pipes and fittings with an estimated five-year spending total of $28.7 million. Supply contracts typically require 24- to 48-hour delivery, F.O.B. destination, firm pricing for the contract term, and compliance with state utility contractor licensing and American Iron and Steel requirements where federal funding is involved. Construction projects incorporating piping often carry DBE participation goals and prevailing wage requirements under Davis-Bacon Act provisions.
