UNSPSC 40174100: Pipe socketweld flanges

UNSPSC 40174100 Pipe socketweld flanges is a Class code covering cast iron and ductile iron flanged fittings, mechanical joint restraining devices, and related water-system piping components that state and local water utilities, public works departments, and municipalities procure for infrastructure maintenance and capital projects. Recent solicitations show water agencies buying standard flanged fittings (reducers, tees, outlets), mechanical joint restraint devices for ductile iron pipe (DIP) and polyvinyl chloride (PVC) pipe in multiple sizes with accessory packages (gaskets, bolts, nuts), and miscellaneous water-system fittings (bushings, couplings, elbows, gate valves, meter stops, saddle tees) to AWWA, ASTM, and ANSI standards. Issuing bodies include city water utilities (Phoenix Water Services, Tampa), county public works and water agencies (Santa Clara County, Palm Beach County), and transit or capital-improvement authorities managing pavement and infrastructure projects. Palm Beach County, Santa Clara County, and Phoenix Water Services appear as repeat buyers in recent postings.

The code shows recent activity concentrated in California and Florida. Representative opportunities include Palm Beach County's IFB 26-038/RR (issued April 22, 2026; due June 4, 2026) for mechanical joint restraining devices on a term contract with estimated contract value of $200,000 over twelve months; City of Phoenix Water Services' IFB 260217 (issued February 23, 2026; due February 19, 2026) for a five-year water pipe and miscellaneous fittings contract with 15 product groups and no stated budget; City of Tampa's RFQ 26-P-00152 (issued March 9, 2026; due February 25, 2026) for standard class 125 flanged fittings; and Santa Clara County's ITB ITBRDAFY260694 (issued April 29, 2026; due May 21, 2026) for the Central Expressway Pavement Rehabilitation Project. Palm Beach County applies a ten percent SBE price preference when bids fall within ten percent of the lowest non-SBE bid, and a five percent local preference for bidders with permanent business presence in Palm Beach County or the Glades. Phoenix Water Services requires DBE compliance under 49 C.F.R. Part 26, five years' operational history, local inventory capability, and one-year warranty coverage.
