UNSPSC 40173700: Pipe reducing flanges

Reducing flanges are used on pipes. They are commonly used in the chemical industry and other proccess industries as well

UNSPSC 40173700 Pipe reducing flanges, a Class code, encompasses cast iron and ductile iron pipe fittings, mechanical joint restraining devices, and flanged reducers and outlet fittings that state and local water and transportation authorities procure for infrastructure repair, installation, and maintenance. Recent state and local opportunities show procurement of Class 125 flanged fittings in multiple sizes, ductile iron pipe mechanical restraining devices with accessory packages, and integrated water system components across cities and counties. The issuing bodies include city water departments, county commissions, and county transportation agencies; Palm Beach County Board of County Commissioners and the City of Phoenix Water Services Department appear as repeat or substantial buyers of these components. Work typically involves supply contracts with fixed unit pricing, delivery requirements, and warranty provisions, frequently structured as competitive sealed bids with multiple-year terms and renewal options.

Geographic activity centers on Florida and Arizona based on recent opportunities. The City of Tampa issued an RFQ for Standard Class 125 flanged fittings (26P00152, RFQ, due February 25, 2026) specifying six-inch, four-inch outlet flanges and reducers with ten-day delivery and one-year contract terms. Palm Beach County Board of County Commissioners solicited mechanical joint restraining devices for ductile iron and PVC pipe in sizes three to fifty-four inches (IFB 26-038/RR, due June 4, 2026, estimated value $200,000 over twelve months) on a lot-by-lot basis with SBE price preference and local preference provisions. The City of Phoenix Water Services Department issued an IFB for water pipe and miscellaneous fittings including flanges, reducers, and related components across fifteen product groups (IFB260217, due February 19, 2026) for a five-year contract commencing May 1, 2026, requiring five years' prior operation, local inventory capacity, and DBE compliance. Santa Clara County solicited the Central Expressway Pavement Rehabilitation Project (ITBRDAFY260694, ITB, due May 21, 2026), which includes infrastructure components but shows limited relevance to reducing flanges or mechanical joint restraining devices as primary procurement focus.
