UNSPSC 40172606: Malleable iron pipe coupling

Pipe coupling made of malleable iron

UNSPSC 40172606 Malleable iron pipe coupling is a Commodity code that captures water infrastructure materials and fittings used in municipal utility systems, though the recent solicitations show this code applied to a broader range of coupling, fitting, and piping products than the strict code name suggests. State and local water utilities, county utility authorities, and municipal water departments are the primary buyers under this code. The work includes procurement of malleable iron and ductile iron fittings, bypass spools, tailpieces, couplings, gate valves, curb stops, meter stops, clamps, reducers, and related water system components for meter assemblies, distribution networks, and treatment plant infrastructure. Specifications typically mandate compliance with American Water Works Association (AWWA), American Society for Testing and Materials (ASTM), and American National Standards Institute (ANSI) standards, with potable water components requiring NSF certifications. Materials must be new and American-made where required by statute. Five-year renewable contracts are standard, with as-needed supply arrangements and monthly invoicing or quarterly pricing reviews common.

Water utilities in the South and Southwest dominate recent activity. The City of Phoenix Water Services Department has posted multiple five-year supply contracts (IFB-26-0217 for water pipe and miscellaneous fittings due February 19, 2026, and IFB-26-0112 for bypass spools and tailpieces due November 12, 2025), Volusia County, Florida issued an ITB for Materials for Water and Sewer Operations due February 4, 2026, and Gwinnett County Board of Commissioners in Georgia solicited replacement particle counters for filter plants due May 8, 2026. Jackson County Utility Authority in Mississippi posted a request for quotes for the South Central Septic Abatement Project due July 8, 2026, with BABA certification required and RESTORE grant funding. Contracts typically include DBE participation requirements, prevailing wage compliance where federally funded, and minimum insurance of $1,000,000 to $2,000,000 general liability. Award is made to the lowest responsive and responsible bidder, with prices firm for 90 to 180 days initially and subject to annual redetermination based on documented material or labor cost increases.
