UNSPSC 40174311: Spacer inner/outer tube

Pipeline support flexible spacer inner/outer tube are used to support and electrically insulate a pipeline from a casing pipe through which it must pass. Typical uses include river, canal and bridge crossings, as well as road and rail crossings.

UNSPSC 40174311 Spacer inner/outer tube is a Commodity code that sees minimal alignment with state and local procurement activity in the recent record. The code's nominal scope—mechanical spacer tubes used in industrial assemblies—does not match the work actually appearing in tagged opportunities. Recent solicitations under this code instead reflect broad infrastructure procurement for water, stormwater, and wastewater pipe systems, industrial supply contracts, and specialty equipment far removed from spacer-tube component work. The City of Phoenix Public Works Department, City of Sarasota, Orange County Florida, and cities in Georgia and Florida are the primary issuing bodies, representing municipal water utilities, public works departments, and county infrastructure agencies. These jurisdictions are bidding comprehensive piping infrastructure, fittings, valves, and related appurtenances—not spacer tubes—indicating a classification mismatch rather than active commodity-level demand.

Geographic activity concentrates in Florida (Phoenix, Sarasota, Orange County, Palm Bay) and Georgia (Calhoun, Lavonia, Gwinnett County), with one representative solicitation in California. Representative recent opportunities include the City of Phoenix Public Works Department IFB 26-SW-0379 (posted July 8, 2026, due August 12, 2026) for supply of industrial pipe, miscellaneous fittings, and equipment on an as-needed basis for a three-year term with optional extensions; Orange County Florida ITB Y26-126 (responses due January 22, 2026) for sewer pipes and fittings spanning 56 line items with an estimated five-year spending total of approximately $28.7 million; and the City of Calhoun, Georgia BID 2026-00299 (due June 18, 2026) for materials supplies for water main relocation including ductile iron and PVC piping. The code produces no decision-relevant signal for spacer-tube suppliers; activity tagged to this code reflects systemic classification error rather than genuine commodity demand.
