UNSPSC 31311702: Carbon steel bonded pipe assemblies

UNSPSC 31311702 Carbon steel bonded pipe assemblies is a Commodity code covering industrial and municipal piping materials supplied on as-needed and annual-term bases to support water, wastewater, stormwater, and airport infrastructure maintenance and construction. Recent state and local solicitations under this code show demand for HDPE pipe assemblies, polyvinyl chloride (PVC) pipe, concrete pipe with lift holes and flared ends, ductile iron pipe, fiberglass-reinforced polymer mortar (FRPM) pipe, and related fittings, couplings, elbows, and installation materials. Issuing bodies include city public works departments, county boards of commissioners, water authorities, airport departments, and municipal utilities; the City of Phoenix has posted multiple overlapping solicitations for industrial pipe supply under this code, signaling sustained demand from large municipal aviation and utilities operations. The scope spans as-needed inventory supply contracts with 24- to 48-hour delivery windows, annual term requirements contracts with firm fixed pricing, and longer-term master agreements (three to five years with renewal options) that allow the procuring agency to call off materials without predetermined quantities. Contractors must typically maintain local inventory, provide downloadable catalogs or interactive pricing systems, meet delivery commitments, hold applicable business and liability insurance, and comply with local small business participation plans and federal nondiscrimination requirements including DBE-N (Disadvantaged Business Enterprise - Neutral) programs where applicable, E-Verify employment verification, and buy-in requirements under BABA (Buy America, Build America).

Geographic activity concentrates in Florida (Palm Bay, Orange County, Brevard County for stormwater and drainage projects), Georgia (Colquitt County, Clayton County Water Authority, Augusta for concrete and fiberglass pipe), Arizona (Phoenix), and Texas (Dallas, Arlington); activity also spans California (Santa Clara County) and shows broad state-local engagement. Representative recent opportunities include the City of Phoenix Public Works Department IFB 27-SW-0447 (posted September 30, 2026, due September 30, 2026) soliciting HDPE and PVC pipe, fittings, and hand tools for three-year supply to three Phoenix-area airports with two optional one-year renewals; Colquitt County (Georgia) sealed-bid procurement for concrete pipe with lift holes and flared ends (posted September 14, 2026, due October 14, 2026) for one-year annual supply; the City of Augusta (Georgia) ITB 27-116 (posted September 10, 2026, due September 29, 2026) for HDPE pipe, couplings, and end sections for stormwater down-drain maintenance under MWBE and local-bidder-preference rules; and the City of Dallas Water Utilities Department BG2600030409 (posted May 14, 2026, due June 12, 2026) establishing a five-year ID/IQ master agreement for ductile iron pipe supply. Opportunities span both recurring commodity supply (as-needed pipe and fittings inventory) and project-specific infrastructure work (stormwater rehabilitation, pipe replacement, bridge projects), with pricing models ranging from per-unit firm-fixed rates to lump-sum project delivery with progress payments.
