UNSPSC 31311101: Aluminum solvent welded pipe assemblies

UNSPSC 31311101 Aluminum solvent welded pipe assemblies is a Commodity code, yet the recent state and local opportunities tagged under it reveal little alignment with the code's nominal scope. The solicitations instead span industrial pipe supply (HDPE and PVC), stormwater and outfall pipe replacement, bridge construction, water treatment plant improvements, and landscaping—none of which center on aluminum solvent welded assemblies as a primary procurement line item. The City of Phoenix Public Works Department and City of Phoenix Aviation Department have posted two as-needed supply contracts for industrial pipe and fittings (IFB 26-SW-0379 and IFB 27-SW-0447), both three-year agreements with two optional one-year extensions commencing December 1, 2026, covering HDPE pipe (1.5 to 24 inches diameter), PVC pipe (0.75 to 4 inches diameter), elbows, couplings, glue, and hand tools with 24- to 48-hour delivery requirements and local inventory maintenance mandates. The City of Augusta, Georgia posted ITB 27-116 on September 10, 2026, due September 29, seeking various HDPE pipe, couplings, and end sections for down-drain installation on an as-needed basis under a one-year initial term with four optional one-year renewals. The City of Fort Worth posted RFP 26-0222 on June 24, 2026, due July 23, for aluminum, iron, rebar, and steel materials on an as-needed basis with a 30 percent small business participation goal and one-year initial term with up to five optional renewals.

Collier County, Florida dominates recent activity with multiple construction projects that tangentially reference piping systems but are primarily scoped as general site work, water treatment facilities, and infrastructure restoration rather than aluminum solvent welded pipe procurement. The county posted IFB 26-8703 for the Immokalee Sports Complex Phase 1A & 1B (bids due November 2, 2026, $6.24 million budget), ITB 26-8700 for Freedom Park Boardwalk Repairs (bids due November 6, 2026, $1.3 million budget), and IFB 26-8683R for South County Regional Water Treatment Plant lime softening improvements with a blend tank (bids due September 21, 2026, $4.27 million budget), among others. Orange County, Florida solicited emergency bridge replacements (Y26-742, estimated $6.2 million), and Palm Bay, Florida posted pipe replacement and stormwater infrastructure work. Activity is concentrated in Florida (Collier County, Orange County, Palm Bay, and Brevard County), Arizona (Phoenix), Georgia (Augusta), Texas (Fort Worth), and California (Santa Clara County). The code shows minimal recent activity squarely addressing aluminum solvent welded pipe assemblies as a standalone commodity, suggesting either misclassification of posted opportunities or limited state and local demand under this specific code in the current market window.
