UNSPSC 31311409: Stainless steel ultra violet welded pipe assemblies

UNSPSC 31311409 Stainless steel ultra violet welded pipe assemblies is a Commodity code representing specialized metal piping products that state and local governments procure for water, wastewater, stormwater, and utility infrastructure projects. Recent state and local solicitations under this code show little direct demand for stainless steel UV-welded assemblies; instead, the procurement landscape is dominated by reinforced concrete pipe (RCP), high-density polyethylene (HDPE), polyvinyl chloride (PVC), ductile iron, and corrugated metal pipe for municipal water distribution, sewer systems, stormwater management, and outfall replacement work. The issuing bodies span state departments, county governments, municipal water and public works departments, and special-purpose utilities—including the State of California, Orange County Florida, the City of Phoenix Public Works Department, Broward County, Gwinnett County Georgia, and smaller municipal authorities in Georgia and Florida. Welding and fabrication services appear in the dataset through Broward County's open-end contract for steel, stainless steel, and aluminum welding and fabrication at water treatment plants and wastewater facilities, suggesting that welded assemblies and fabricated components are purchased as services rather than prefabricated pipe products.

Geographic activity centers on Florida and Georgia, with secondary activity in California and Arizona. Representative recent opportunities include Broward County's RFP for welding and fabrication services (due July 1, 2026) covering portable and shop welding on steel and stainless components at water and wastewater facilities; Gwinnett County's IFB for annual stormwater pipe supply (due May 19, 2026) encompassing RCP, HDPE, and corrugated metal in standardized diameters; and the City of Palm Bay's ITB for I-95 outfall pipe replacement (due July 14, 2026) requiring removal and installation of replacement outfall piping infrastructure in Brevard County. Orange County Florida's invitation for sewer pipes and fittings (due January 22, 2026, with estimated five-year spending of approximately $28.7 million) reflects the scale and frequency of municipal pipeline procurement in the region. The code shows minimal recent solicitation activity specifically for stainless steel UV-welded assemblies as finished goods; state and local demand appears directed toward standard pipe materials (concrete, plastic, metal) purchased as commodity supplies or custom welding services performed on-site, rather than prefabricated specialized assemblies.
