UNSPSC 31311109: Stainless steel solvent welded pipe assemblies

UNSPSC 31311109 Stainless steel solvent welded pipe assemblies, a Commodity code, shows limited recent state and local procurement activity aligned with its nominal scope. The few recent opportunities tagged under this code predominantly solicit industrial pipe, fittings, and materials for water, wastewater, and stormwater infrastructure rather than stainless steel solvent welded assemblies specifically. The City of Phoenix Public Works Department's IFB 26-SW-0379 (due August 12, 2026) for industrial pipe, miscellaneous fittings, and equipment on an as-needed basis spans three years with two optional one-year extensions and emphasizes delivery within 24 to 48 hours from purchase order date with local inventory maintenance; however, the scope covers High-Density Polyethylene (HDPE) and Polyvinyl Chloride (PVC) pipe rather than stainless steel. Broward County's RFP OPN2131884B2 (due July 1, 2026) for welding and fabrication services encompasses work on steel, stainless steel, aluminum, and black steel components at county water and wastewater facilities, including portable and shop welding with hourly labor rates, emergency availability, and surface preparation. Issuing bodies soliciting under or near this code include state procurement offices (State of California), counties (Orange County and Broward County, Florida; Gwinnett County and Notla Water Authority, Georgia; Santa Clara County, California), cities (Phoenix, Lawrenceville, Palm Bay, Tucson, Lavonia), and a university (University of Wisconsin-Madison), with water and wastewater infrastructure dominating the activity.

Recent activity clusters in Florida (Orange County, Palm Bay, Broward County), Georgia (Gwinnett County, Notla Water Authority, Lawrenceville, Lavonia), California (State of California, Santa Clara County), and Arizona (City of Phoenix, City of Tucson). The California State procurement RFBIS27200030 (due July 29, 2026) solicits steel materials or products under a competitive bidding process with attached technical specifications and price lists, though specific items and quantities are not disclosed in the summary. The code shows sporadic activity across water treatment plant upgrades, stormwater and sewer infrastructure replacement and rehabilitation, and general industrial piping supply contracts. The mismatch between the code's nominal scope—stainless steel solvent welded pipe assemblies—and the broader industrial piping and materials sourced in recent opportunities suggests that state and local procurement offices may be using this code loosely to tag general pipe and fitting supply and fabrication work. Vendors targeting this code should review full solicitation documents to confirm whether work actually requires stainless steel solvent welded assemblies or instead encompasses standard carbon steel, HDPE, PVC, or ductile iron piping with fabrication or welding services.
