UNSPSC 40180000: Tubes tubing and tube fittings

Lengths or sections of hollow cylinders for the conveyance of liquids or gases. Similar to pipe except that tubing usually implies tighter engineering requirements than pipe.

UNSPSC 40180000 Tubes tubing and tube fittings (Family) encompasses supply contracts for industrial and utility-grade piping, tubing, fittings, and related components that state and local governments procure for water and wastewater systems, stormwater infrastructure, chemical handling, and facility maintenance. Recent opportunities show agencies buying ductile iron pipe for potable water distribution, HDPE and PVC piping for municipal utilities, chemical-resistant plastics for disinfectant injection systems, copper tubing for facility plumbing, stainless steel pipe for specialized applications, and comprehensive fittings (elbows, couplings, unions, tees, adapters, valves) supporting installation and repair across multiple infrastructure classes. Issuing bodies span water utilities (City of Phoenix Public Works, Tucson Water, City of Arlington Water Utilities, Broward County Water and Wastewater Services), county engineering departments (Collier County, Orange County Florida), municipal purchasing offices (City of Tampa, City of Dallas, City of Brockton Massachusetts), and specialized districts (Alameda County Water District, Lubbock Power & Light). The Family code sees activity across municipal water treatment plant construction, emergency outfall pipe replacement, routine supply-and-delivery contracts, and capital rehabilitation projects at operating facilities.

Recent opportunities cluster in Florida (Orange County, Collier County, Palm Bay, Tampa, Broward County), Texas (Phoenix Arizona, Dallas, Arlington, Lubbock), California (San Mateo County, Santa Clara County, Alameda County), Massachusetts (Brockton), and Connecticut (Meriden), reflecting national water infrastructure investment cycles. Representative recent solicitations include the City of Tampa's ITB 26-P-00565 (October 16, 2026 response date) for 4" to 6" ductile iron pipe supply with a five percent SLBE bid discount; the City of Phoenix Public Works IFB 27-SW-0447 (September 30, 2026, three-year supply contract with options for extension) for HDPE pipe 1.5" to 24" diameter and PVC pipe 0.75" to 4" diameter under FAA Grant Assurances and DBE-N compliance; Collier County's sealed bid solicitation (September 21, 2026 deadline) for a $4.27 million lime-softening blend-tank construction project incorporating 180 linear feet of 42-inch and 130 linear feet of 36-inch ductile iron piping with Schedule 80 CPVC chemical lines; and Broward County's ITB OPN2131840B1 (June 23, 2026) for an open-end indefinite-quantity contract supplying new well column pipes in 6" to 12" diameters with SBE and local-vendor preferences applied. Pricing structures vary—some contracts fix unit prices for the term; others allow CPI-indexed annual adjustments. Prevailing wage, E-Verify compliance, insurance requirements ($500,000 to $2 million general liability thresholds), and performance bonds are routine. Award timelines extend 30 to 90 days post-bid opening.
