UNSPSC 31311101: Aluminum solvent welded pipe assemblies

UNSPSC 31311101 Aluminum solvent welded pipe assemblies is a Commodity code that in recent state and local practice encompasses industrial piping supply on an as-needed basis, including HDPE and PVC pipe ranging from 0.75 to 24 inches in diameter, applicable fittings such as elbows and couplings, and related hand tools and glue. State and local buyers under this code include cities (Phoenix, Fort Worth, Palm Bay), counties (Collier County, Orange County, Santa Clara County), and regional authorities across Florida and the Southwest. The City of Phoenix Public Works Department, Collier County, and the City of Palm Bay appear as repeat procurement bodies. Scope of work spans routine supply agreements with firm pricing, 24- to 48-hour delivery commitments, local inventory maintenance, and website-based order management; contractors must provide downloadable or interactive catalogs and manage multiple customer accounts. Representative recent opportunities include the City of Phoenix Public Works Department's IFB 26-SW-0379 for supply of industrial pipe, miscellaneous fittings, and equipment on a three-year term with two one-year extensions, with sealed offers due August 12, 2026 and contract start December 1, 2026; Collier County's Bid 26-8683 for SCRWTP Lime Softening Improvements with sealed bids due July 15, 2026 (later posted as July 1, 2026), encompassing construction and supply of Schedule 80 CPVC chemical injection piping and ductile iron piping with an anticipated budget of $3.29 million; and the City of Fort Worth's RFP 26-0222 for aluminum, iron, rebar, and steel materials on an as-needed basis with proposals due July 23, 2026 and a 30 percent small business participation goal.

Geographic activity concentrates in Florida (Collier County, Orange County, Palm Bay) and Arizona–Texas (Phoenix, Fort Worth), with secondary activity in California (Santa Clara County). The code shows meaningful activity in infrastructure and water treatment upgrades where piping supply and installation occur concurrently. Vendors pursuing work under this code should be prepared to meet rapid delivery timelines (24–48 hours), maintain local inventory or secure binding supplier contracts, comply with E-Verify and bonding requirements, and carry commercial general liability insurance of at least $1 million per occurrence. DBE-N and small business participation goals appear frequently in these opportunities, particularly in Phoenix (DBE-Neutral under 49 CFR Part 26) and Fort Worth (30 percent SBP goal for certified small businesses in five-county region). Repeat buyers and established supply relationships offer stable pipeline activity, but competition is active and pricing pressure is significant given the commodity nature of these products.
