UNSPSC 31311305: Low alloy steel bolted pipe assemblies

UNSPSC 31311305 Low alloy steel bolted pipe assemblies is a Commodity code. State and local governments soliciting under this code buy industrial pipe, fittings, and related materials for water and wastewater infrastructure, stormwater systems, natural gas distribution, and construction projects. Recent opportunities show demand for reinforced concrete pipe (RCP), high-density polyethylene (HDPE) pipe, polyvinyl chloride (PVC) pipe, corrugated metal pipe, ductile iron pipe, and associated fittings and valves in sizes ranging from under one inch to 90 inches in diameter. Issuing bodies include state departments, county governments, cities, and special-purpose water authorities. Jurisdictions typically structure these as multi-year supply contracts with firm pricing, as-needed or annual ordering, and delivery windows of 24 to 48 hours for stocked items or 14 days for special orders. Some contracts require local inventory maintenance and dedicated account management. Broward County and Orange County, Florida appear as repeat procurers; Orange County's five-year sewer pipes and fittings contract estimated at approximately $28.7 million in total spending signals sustained demand for this commodity class in that region.
