UNSPSC 40171601: Industrial welded carbon steel pipe

Pipe with a pressure rating of more than 2500 psi made of welded carbon steel

UNSPSC 40171601 Industrial welded carbon steel pipe is a Commodity code that covers the supply of carbon steel pipe products to state and local water utilities, wastewater agencies, public works departments, and other infrastructure authorities. State and local governments buy this material primarily for pipeline installation, replacement, and infrastructure maintenance projects—including water distribution system upgrades, stormwater outfall replacement, natural gas pipeline installation, and sewerage system improvements. Recent solicitations show demand for both specialty applications (such as outfall pipes governed by environmental permits) and routine supply contracts supporting ongoing utility operations.

The issuing-body mix spans state departments, county water authorities, city public works and utilities divisions, and regional transit authorities. The State of California, Orange County and the City of Palm Bay in Florida, Broward County in Florida, Gwinnett County in Georgia, the City of Lawrenceville in Georgia, and the City of Phoenix in Arizona have all posted activity under or adjacent to this code in the past ninety days. Representative recent opportunities include the State of California's RFB for steel materials posted July 14, 2026, with bids due July 29, 2026; the City of Phoenix Public Works Department's IFB 26-SW-0379 for industrial pipe, miscellaneous fittings, and equipment (HDPE and PVC, not carbon steel) posted July 8, 2026, with offers due August 12, 2026; and Gwinnett County's Invitation to Bid BL079-26 for stormwater pipe on an annual contract, posted April 16, 2026, with bids due May 19, 2026, covering reinforced concrete, HDPE, and corrugated metal pipe across multiple diameter and material specifications. Recent activity concentrates in California and Florida, with secondary activity in Georgia, Arizona, and other states. Many of these procurements involve multi-year supply or framework agreements with as-needed ordering, fixed unit pricing, and strict delivery timelines (24–48 hours in competitive markets); some carry federal compliance requirements including DBE participation, prevailing wage, American Iron and Steel certifications, or environmental permitting obligations tied to water infrastructure grants.
