UNSPSC 31311402: Carbon steel ultra violet welded pipe assemblies

UNSPSC 31311402 Carbon steel ultra violet welded pipe assemblies is a Commodity code capturing industrial and municipal pipe supply and fabrication services, though recent state and local activity under this code shows minimal direct solicitation for UV-welded carbon steel assemblies specifically. The code appears in the procurement landscape primarily through broader infrastructure and water utility projects that may incorporate welded pipe components as subordinate materials within larger construction or systems-integration scopes, rather than as standalone supply contracts focused on the welded assembly product itself.

State and local issuing bodies pursuing pipe and related infrastructure work span county water authorities, municipal departments, and transit agencies across Florida, Georgia, California, and Arizona. The City of Phoenix Public Works Department solicited industrial pipe and fittings (IFB 26-SW-0379, due August 12, 2026) on a three-year renewable term for as-needed supply of HDPE and PVC pipe, fittings, glue, and hand tools with 24–48-hour delivery and local inventory requirements. Broward County issued an RFP for welding and fabrication services (OPN2131884B2, due July 1, 2026) covering portable and shop welding on steel and stainless steel components at water and wastewater facilities, with AWS Welder Certification required. Orange County, Florida solicited sewer pipes and fittings (Y26-126, due January 22, 2026) with an estimated five-year spend of $28.7 million covering PVC, ductile iron, valves, and manhole components. Gwinnett County (Georgia) issued a bid for stormwater pipe on an annual contract (BL079-26, due May 19, 2026) encompassing reinforced concrete, HDPE, and corrugated metal pipe in various diameters. The City of Lawrenceville (Georgia) sought a supplier for natural gas pipe and materials storage with just-in-time delivery coordination (PE66751NONST2027000000096, due July 23, 2026). These procurements reflect water, wastewater, stormwater, and gas utility system modernization and maintenance, but the source does not identify specific recent solicitations for carbon steel UV-welded pipe assemblies as a distinct product line, and the code's activity remains obscure relative to the broader pipe supply and fabrication work documented in the recent opportunities block.
