UNSPSC 31311705: Low alloy steel bonded pipe assemblies

UNSPSC 31311705 Low alloy steel bonded pipe assemblies is a Commodity code that in recent state and local procurement activity encompasses industrial pipe supply, piping infrastructure replacement, and stormwater/sewer system materials — though the actual solicitations diverge substantially from the code's nominal scope. City and county water, public works, and utilities departments are the primary issuing bodies. The City of Phoenix Public Works Department solicited sealed offers for industrial pipe, miscellaneous fittings, and equipment (IFB 26-SW-0379, due August 12, 2026) covering HDPE and PVC pipe ranging from 0.75 to 24 inches in diameter, elbows, couplings, glue, and hand tools on an as-needed basis for a three-year term with two optional one-year extensions. The City of Dallas Water Utilities sought competitive bids for a five-year indefinite delivery/indefinite quantity master agreement for ductile iron pipe (BG2600030409, due June 12, 2026). Orange County, Florida Utilities Division posted a five-year sewer pipes and fittings procurement encompassing 56 line items of PVC and ductile iron pipes, fittings, valves, manhole components, and miscellaneous supplies (IFB Y26-126, due January 22, 2026), with an estimated five-year spending total of approximately $28.7 million. The Clayton County Water Authority in Georgia issued a Notice of Sole Source Intent for fiberglass reinforced polymer mortar (FRPM) pipe in sizes from 18 to 60 inches for sewer replacement, with an estimated total cost of $6.07 million (due May 13, 2026).

Recent activity concentrates in Florida and Texas, with additional solicitations in Georgia and California. The City of Palm Bay, Florida requested bids for the I-95 Outfall Pipe Replacement project (ITB 41ITB26, due July 14, 2026) involving removal and installation of replacement outfall pipe infrastructure governed by Florida Department of Environmental Protection permits. Santa Clara County, California solicited bids for the Central Expressway Pavement Rehabilitation Project (ITBRDAFY260694, due May 21, 2026) including extensive scope with pavement rehabilitation, partial depth recycling, and asphalt overlay among other improvements. The City of Palm Bay also conducted a Request for Information on stormwater pipe rehabilitation and replacement solutions along the Malabar Road corridor (38RFI26, due June 9, 2026) as a pre-solicitation information-gathering initiative. The code shows moderate recent activity but the disconnect between the code's stated scope (low alloy steel bonded pipe assemblies) and actual solicitations (predominantly PVC, ductile iron, HDPE, and FRPM materials) suggests this code may not capture the full breadth of industrial pipe procurement occurring under state and local notices.
