UNSPSC 31311112: Copper solvent welded pipe assemblies

UNSPSC 31311112 Copper solvent welded pipe assemblies is a Commodity code, and state and local governments procure copper pipe components and related assemblies primarily for water distribution, plumbing, and outfall infrastructure work. Recent opportunities show water utilities and municipalities buying copper tubing, water pipe fittings, and associated components—often as part of broader pipe-and-fitting supply contracts or integrated construction projects. The City of Phoenix Water Services Department issued an IFB for water pipe and miscellaneous fittings (including couplings, elbows, gate valves, and flanges) under a five-year contract; the Alameda County Water District solicited copper tubing in specific Cambridge-Lee Industries brands and diameters; and the School Board of Sarasota County sought time-and-materials plumbing services requiring licensed technicians and materials supply. Issuing bodies include city water and public works departments, county utilities and water districts, and school facilities operations—a mix of municipal and special-purpose water authorities. Geographic activity concentrates in Florida (Phoenix, Orange County, Palm Bay, Pasco County, Sarasota) and California (Alameda County), with secondary activity in South Carolina and Texas driven by larger waterline replacement and street reconstruction projects.

The code sees activity in both as-needed supply contracts and integrated construction delivery. The City of Phoenix Public Works Department's IFB for industrial pipe, miscellaneous fittings, and equipment (due August 12, 2026) requires 24- to 48-hour delivery and local inventory support for HDPE and PVC pipe in multiple sizes, with firm pricing for three years plus optional extensions. Orange County, Florida's five-year sewer-pipes-and-fittings contract (responses due January 22, 2026) estimated $28.7 million in spending and required pricing as percentage discounts from manufacturer suggested retail price, with Service Disabled Veteran Business preferences tiered from 8% down to 3% depending on bid value. Waterline replacement and pavement rehabilitation projects (such as Barnwell County's Heyward Street waterline installation and the City of San Antonio's Gardendale Street reconstruction) incorporate copper and other pipe assemblies as line items within larger construction scopes. Pursuit depends on vendor capacity for rapid delivery, local inventory maintenance, and ability to meet municipal standards (AWWA, ASTM, ANSI, NSF certifications for potable water); DBE and small-business compliance is standard across these jurisdictions.
