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 does not reflect the actual work state and local governments are buying under this classification. Recent opportunities tagged to the code show no procurement of spacer tubes; instead, they document water and sewer infrastructure projects involving pipe, fittings, valves, and related distribution materials. The City of Phoenix Public Works Department, the City of Augusta, the Douglasville-Douglas County Water and Sewer Authority, and the County of DeKalb have all posted solicitations for industrial pipe (HDPE and PVC), couplings, elbows, wyes, and related fittings for water mains, sewer lines, and stormwater systems on as-needed supply basis. These acquisitions span three-year to one-year contract terms with firm pricing and strict delivery requirements (24–48 hours for Phoenix; 60 days for Augusta; no minimum-order constraints mandated). The issuing bodies include municipal public works departments, county water authorities, and county purchasing offices—primarily mid-sized Southern and Western cities and counties managing routine maintenance and capital replacement of buried utility infrastructure.

Geographic activity concentrates in Georgia (Augusta, DeKalb County, Calhoun, Lavonia) and Arizona (Phoenix), with secondary activity in Florida (Sarasota, Palm Bay, Orange County) and California (Santa Clara County). The City of Phoenix has posted two substantially identical IFBs for industrial pipe and fittings (IFB 26-SW-0379 in August 2026 and IFB 27-SW-0447 in September 2026), both for three-year supply contracts commencing December 1, 2026, suggesting either reissuance or parallel procurement lines. The City of Augusta issued ITB 27-116 (bids due September 29, 2026) for HDPE pipe and couplings in diameters 8 to 36 inches with one-year term and four optional renewals. The Douglasville-Douglas County Water and Sewer Authority issued IFB 327 (bids due October 7, 2026) for annual water and sewer pipe fittings and related materials covering one-year term from December 20, 2026. The code itself appears misaligned with procurement reality—the taxonomy label "spacer inner/outer tube" has no observable match in these solicitations, which acquire bulk utility piping, standard fittings, and appurtenances rather than precision spacer components.
