UNSPSC 31311313: Brass bolted pipe assemblies

UNSPSC 31311313 Brass bolted pipe assemblies (Commodity) covers industrial and water-system piping components—including fittings, valves, couplings, and related hardware—that state and local water utilities, public works departments, and infrastructure agencies procure on supply, as-needed, or project bases. Recent solicitations show the code capturing broader pipe and fitting procurement activity than the nominal commodity name suggests; actual buys include PVC and HDPE pipe, isolation valves, fire hydrant appurtenances, ductile iron pipe, and mixed-material assemblies for water mains, stormwater systems, and municipal outfall replacement. Issuing bodies are predominantly municipal water and public works departments, with repeat activity from Arizona, Florida, and California municipalities including the City of Phoenix, Orange County Florida, and City of Palm Bay, alongside county water districts and school facility maintenance programs. State and local procurement offices use this code for both standing supply agreements and discrete capital projects in water infrastructure.

Recent activity concentrates in Florida and the Southwest. The City of Phoenix Water Services Department issued an IFB for water pipe and miscellaneous fittings (IFB260217, due February 19, 2026) covering 15 product groups with a five-year term; the same City's Public Works Department solicited industrial pipe, fittings, and equipment on an as-needed basis (IFB26SW0379, due August 12, 2026) with a three-year initial term and two one-year options, emphasizing 24-to-48-hour delivery and local inventory requirements. Orange County, Florida awarded a five-year sewer pipes and fittings contract (Y26-126, closed January 22, 2026) with an estimated five-year spend of approximately $28.7 million and aggressive delivery timelines (emergency fills within four hours, standard within two days). Barnwell County, South Carolina's waterline replacement project (CIP-2257, due August 4, 2026) specified eight-inch and four-inch water mains with isolation valves and fire hydrant installation. Alameda County Water District procured specific copper tubing inventory (IFB252636, due April 27, 2026). The code shows consistent activity across municipal supply chains and capital water projects, with emphasis on rapid fulfillment, local stock, and compliance with American Water Works Association and NSF potable-water standards.
