UNSPSC 40171501: Commercial welded carbon steel pipe

Pipe with a pressure rating of 2500 psi or less made of welded carbon steel

UNSPSC 40171501 Commercial welded carbon steel pipe is a Commodity code that state and local governments procure for water infrastructure, stormwater systems, and natural gas pipeline projects. Recent solicitations show jurisdictions buying industrial pipe materials—including carbon steel, polyethylene, PVC, and reinforced concrete pipe—on open-end supply contracts with delivery and inventory requirements, as well as incorporated into larger construction projects for treatment plants, pump stations, and outfall replacements. The issuing-body mix spans state procurement offices, counties, cities, water authorities, and transit-connected agencies. The State of California issued a competitive bid (RFB-IS-27200030, due July 29, 2026) for steel materials with attached technical specifications and price lists; the City of Phoenix Public Works Department solicited a three-year IFB for industrial pipe, fittings, and equipment (IFB 26-SW-0379, due August 12, 2026) with DBE-N compliance and local inventory requirements; Broward County sought welding and fabrication services (OPN2131884B2, due July 1, 2026) including work on steel components at water treatment plants; and Gwinnett County, Georgia issued a competitive bid for stormwater pipe on annual contract (BL079-26, due May 19, 2026) covering reinforced concrete pipe, HDPE, and corrugated metal pipe in multiple size ranges. Orange County, Florida's sewer pipes and fittings procurement (Y26-126, due January 22, 2026 per latest update) expected approximately $28.7 million in five-year spending for PVC and ductile iron pipes with fast-turnaround delivery. The City of Lawrenceville, Georgia sought just-in-time natural gas pipe and materials supply (PE66751NONST2027000000096, due July 23, 2026) for a DOT project.

Recent activity concentrates in Florida, California, and Georgia, with secondary volume in Arizona and other states. The City of Palm Bay, Florida is replacing outfall pipe infrastructure along the I-95 corridor (ITB 41ITB26, due July 14, 2026) under environmental permits with lump-sum bidding and retainage structures. Notla Water Authority in Georgia procured approximately 2,400 linear feet of 6-inch water line with American Iron and Steel compliance (PE33821NONST2026000000002, due June 18, 2026). Santa Clara County solicited Central Expressway pavement rehabilitation including PCC work (ITBRDAFY260694, due May 21, 2026). The City of Lavonia, Georgia contracted water treatment plant improvements including modifications to settling basins and clearwell storage (PE66940NONST2026000000005, due May 26, 2026) with DBE participation goals and Build America, Buy America Act requirements. Procurement under this code emphasizes firm-fixed pricing, fast delivery (24- to 48-hour windows common), local inventory maintenance, and compliance with environmental permits and domestic content rules. Set-asides and preferences appear in multiple jurisdictions: DBE-N mandates on transit-connected work, SBE/CBE preferences in Broward County, and DBE participation goals in Georgia water projects. The code sees steady, fragmented activity across municipal water departments, stormwater management, and transportation agencies with no single dominant buyer.
