UNSPSC 40175310: Flange insulation kit

Flange insulation kits are the most widely used form of controlling losses due to corrosion. They can be used to control stray electric currents in piping at oil, gas, water, refinery and chemical plants and increase the effectiveness of cathodic protection systems and confine or eliminate electrolytic corrosion..

UNSPSC 40175310 Flange insulation kit, a Commodity code, does not align with the recent state and local procurement activity posted under this classification. The four most recent opportunities solicited under the code involve mechanical joint restraining devices for ductile iron and PVC piping, standard Class 125 flanged fittings for municipal water systems, general water pipe and miscellaneous fittings (bushings, clamps, couplings, gate valves, reducers, saddle tees), and pavement rehabilitation work including guardrail components—none of which constitute flange insulation kits as the code name suggests. State and local water utilities and public works departments appear to be the primary issuing bodies, including the City of Phoenix Water Services Department, the City of Tampa Purchasing Department, Palm Beach County Board of County Commissioners, and Santa Clara County. The code shows activity across California and Florida jurisdictions, with a single Arizona water utility also soliciting under it.

Recent opportunities include Palm Beach County's IFB 26-038/RR for mechanical joint restraining devices (due June 4, 2026), with an anticipated contract value of $200,000 over the initial twelve-month term and SBE and local preference eligibility; the City of Tampa's RFQ 26-P-00152 for Standard Class 125 flanged fittings (due February 25, 2026), a one-year award with no disclosed budget range; the City of Phoenix Water Services Department's five-year IFB 260217 for water pipe and miscellaneous fittings (due February 19, 2026), with no stated award value; and Santa Clara County's ITB ITBRDAFY260694 for the Central Expressway Pavement Rehabilitation Project (due May 21, 2026), a 142-working-day project with no disclosed budget. The mismatch between the code's nominal scope and the actual work being solicited suggests that the code is being misapplied in state and local procurement systems or that flange insulation kits are incidental components within broader water infrastructure or piping supply contracts.
