UNSPSC 31310000: Fabricated pipe assemblies

UNSPSC 31310000 Fabricated pipe assemblies is a Family code, and state and local governments procure industrial pipe, fittings, valves, and related components under it for water, wastewater, and stormwater infrastructure operations. The City of Phoenix Public Works Department's supply solicitation for High-Density Polyethylene (HDPE) and Polyvinyl Chloride (PVC) pipe with fittings and hand tools illustrates the scope: municipalities and counties source these materials on as-needed or annual contract bases to support utility operations, emergency repairs, and new construction. Work ranges from routine inventory replenishment to project-specific procurement tied to capital improvement initiatives.

State and local issuing bodies are predominantly water utilities, public works departments, and municipal utility authorities in counties and cities. Water and sewer operations dominate the activity; recent opportunities include Broward County's open-end indefinite-quantity contract for well column pipes, the City of Arlington's annual requirements contract for HDPE water pipe, and the City of Dallas's five-year ID/IQ master agreement for ductile iron pipe. These are repeat procurement patterns across multiple jurisdictions. Secondary activity includes construction-related pipe procurement supporting infrastructure rehabilitation projects, such as Collier County's blend-tank improvements and the City of Palm Bay's outfall pipe replacement. Geographic concentration is evident in Florida, Texas, and California, with scattered activity across the upper Midwest and Northeast. Representative recent opportunities include the City of Phoenix IFB for industrial pipe, miscellaneous fittings, and equipment with an August 12, 2026 response date, Broward County's ITB for well column pipes due June 23, 2026, and the City of Arlington's solicitation for HDPE water pipe due May 21, 2026. These contracts typically feature firm fixed pricing on an F.O.B. destination basis, 24- to 48-hour delivery capability requirements, and multi-year or annual renewal terms with no guaranteed minimums, reflecting the variable demand patterns characteristic of utility operations.
