UNSPSC 40174700: Pipe threaded flanges

UNSPSC 40174700 Pipe threaded flanges is a Class code covering mechanical joint restraining devices, flanged fittings, and related pipe connection components that state and local governments procure for water distribution, wastewater infrastructure, and municipal utility maintenance. Recent opportunities show jurisdictions acquiring cast iron and ductile iron flanged fittings, reducers, tees, and outlet flanges in multiple sizes; mechanical joint restraining devices for both ductile iron pipe and PVC; and miscellaneous water pipe fittings and accessories including bushings, couplings, elbows, gate valves, and saddle tees. Issuing bodies span city water utilities and departments of public works (City of Phoenix Water Services Department, City of Tampa, City of Brockton Department of Public Works), county transportation and public works agencies (Santa Clara County, Palm Beach County Board of County Commissioners), and municipal procurement departments serving multiple city departments. Most recent solicitations are IFBs and RFQs with fixed-price contracting on one-year to five-year terms, with awards made to lowest responsive bidders or divided by lot. SBE and local business enterprise set-asides and preferences appear regularly: Palm Beach County offers a ten percent SBE price preference and five percent local preference; Tampa identifies SLBE-certified suppliers; and Phoenix applies DBE requirements under 49 C.F.R. Part 26.

The code sees active procurement across the Southwest, Southeast, and Northeast. Phoenix issued a five-year IFB for water pipe and miscellaneous fittings with response due February 19, 2026, requiring five years of prior operation and local inventory sufficient for daily support and next-day delivery on captive parts. Tampa issued an RFQ for Standard Class 125 flanged fittings with response due February 25, 2026, requiring all pricing to include freight and delivery within ten days. Palm Beach County issued IFB #26-038/RR on April 22, 2026, for mechanical joint restraining devices on a term contract with lot-by-lot awards and response due June 4, 2026, with anticipated contract value of $200,000 over the initial twelve-month term. The City of Brockton, Massachusetts Department of Public Works posted a bid for ductile, cast iron, and steel fittings with response due June 4, 2026. All require proof of insurance, E-Verify compliance, and warranty provisions; many impose material standards referencing AWWA, ASTM, and ANSI or NSF potable water certifications.
