UNSPSC 40173000: Pipe half couplings

UNSPSC 40173000 Pipe half couplings is a Class code covering pipe couplings and related threaded or flanged connection fittings that state and local water and sewer utilities procure for distribution infrastructure maintenance and capital improvement. Recent opportunities under this code show mixed scope alignment: water system suppliers are bidding on broad categories of water infrastructure components—bypass spools, tailpieces, flanged fittings, and general water pipe and fittings—where half couplings are one line item among dozens or hundreds. The Jackson County Utility Authority's septic abatement project and the City of Phoenix's water meter assembly and general water pipe procurements exemplify the fragmented buying pattern; utilities issue multi-item material solicitations where coupling products compete alongside valves, clamps, and other distribution components rather than as standalone procurements. Issuing bodies are primarily municipal water and sewer departments (City of Phoenix Water Services, Gwinnett County Department of Water Resources, Volusia County utilities) and special-purpose water authorities, with cooperative purchasing vehicles (Berkshire Regional Group Purchasing Program for Massachusetts municipalities) occasionally including culvert products and related highway supplies where pipe connections are incidental. Geographic activity clusters in water-rich or fast-growth jurisdictions: Arizona (Phoenix), Georgia (Gwinnett, Franklin, and Technical College System), Florida (Volusia), and Massachusetts (Berkshire County multi-municipality cooperative).

Recent representative opportunities include the City of Phoenix Water Services Department's solicitation for water pipe and miscellaneous fittings (IFB 260217, due February 19, 2026, five-year contract commencing May 1, 2026) encompassing 15 product groups with quantities from 2 to over 21,000 units, all materials to conform to AWWA, ASTM, and ANSI standards including NSF certification; and the City of Phoenix's five-year contract for bypass spools and tailpieces (IFB 26-0112, due November 12, 2025) with 132 line items of stainless steel components and ductile iron flanged fittings in sizes 3 to 12 inches, minimum 250 psi working pressure. Volusia County's competitive sealed bid for Materials for Water and Sewer Operations (IFB 26-B-42LS, due February 4, 2026, three-year initial term with two optional one-year renewals) required American-made metal items and AWWA compliance for a comprehensive range including brass fittings, stainless steel clamps, and gate valves. All three are available through procurement portals and require firm pricing for initial contract periods, insurance certifications (minimum $1,000,000 to $2,000,000 commercial general liability), and compliance with federal Davis-Bacon Act or E-Verify standards where funded by federal or state programs.
