UNSPSC 31311202: Carbon steel riveted pipe assemblies

UNSPSC 31311202 Carbon steel riveted pipe assemblies is a Commodity code representing industrial and utility piping materials and related fittings that state and local governments procure for infrastructure maintenance, construction, and repair operations. Recent state and local solicitations under or near this code show mixed scope—while the code name specifies carbon steel riveted assemblies, actual procurement activity encompasses a broader range of industrial piping materials including high-density polyethylene (HDPE) pipe, polyvinyl chloride (PVC) pipe, natural gas pipe, and associated couplings, elbows, and end sections used in water distribution, stormwater management, drainage, and utility infrastructure projects. The issuing bodies soliciting under this code span cities, counties, water authorities, and state agencies. The City of Phoenix Public Works Department has posted two separate IFBs for industrial pipe and miscellaneous fittings (IFB 27-SW-0447 due September 30, 2026, and IFB 26-SW-0379 due August 12, 2026), both three-year supply contracts covering HDPE and PVC piping for Phoenix Aviation Department operations. The City of Augusta, Georgia solicited HDPE pipe and couplings via ITB 27-116 (due September 29, 2026) for drainage installation and maintenance. The City of Lawrenceville, Georgia requested natural gas pipe materials and storage coordination for a DOT project (due July 23, 2026). Notla Water Authority in Georgia solicited approximately 2,400 linear feet of 6-inch water line construction (due June 18, 2026). The City of Palm Bay, Florida issued an RFI on stormwater pipe rehabilitation and replacement along Malabar Road (due June 9, 2026, pre-solicitation phase).

Recent activity concentrates in Arizona, Georgia, and Florida, with additional opportunities in California and across the Southeast. Supply contracts dominate the mix, with pricing structured as per-unit or per-linear-foot firm-fixed rates, typically three-year terms with optional one-year renewals, 24–48-hour delivery requirements, and local inventory maintenance mandates. The City of Phoenix contracts emphasize DBE-Neutral compliance and small-business participation plans tied to federal transit funding. Augusta's procurement applies MBE/WBE utilization requirements and local-bidder preferences under ten percent. Several jurisdictions require E-Verify compliance and state work-authorization verification. Delivery and supply logistics are critical—vendors must maintain stocks supporting daily operations, establish dedicated contract representatives, and provide downloadable product catalogs or interactive ordering systems. Bonds are required in most solicitations (5–105 percent of bid value); insurance requirements typically include general liability ($1–2 million aggregate), workers' compensation, and auto liability coverage. The code shows steady municipal and utility demand but lacks standout concentration among repeat buyers beyond Phoenix's two consecutive IFBs in 2026.
