UNSPSC 40174103: Stainless steel pipe socketweld flange

Pipe socketweld flange made of stainless steel

UNSPSC 40174103 Stainless steel pipe socketweld flange is a Commodity code that captures state and local procurement of pipe fittings and related hydraulic components, though recent solicitations show the code is being applied broadly to general-purpose water infrastructure fittings and joint restraint devices that fall outside the narrow scope of stainless steel socketweld flanges. State and local water utilities, public works departments, and county procurement offices are the primary buyers under this designation. The work involves purchasing prefabricated pipe components, flanged fittings, joint restraining devices, and accessory assemblies (gaskets, bolts, nuts) for water distribution systems, wastewater infrastructure, and pavement rehabilitation projects. Issuing bodies include county water departments, city purchasing offices, and county boards of commissioners conducting term-contract and fixed-unit-price procurements.

Recent activity spans Florida, California, and Arizona. Palm Beach County Board of County Commissioners issued IFB 26-038/RR in April 2026 seeking mechanical joint restraining devices for ductile iron pipe (3-inch to 54-inch diameters) and polyvinyl chloride pipe (3-inch to 24-inch) on a term contract with anticipated value of $200,000 over twelve months, with bids due June 4, 2026, and SBE and local-preference set-asides available. The City of Phoenix Water Services Department posted IFB 260217 in February 2026 for water pipe and miscellaneous fittings across 15 product groups under a five-year contract effective May 1, 2026, with a non-mandatory pre-offer conference scheduled for February 4, 2026, DBE compliance required, and sealed offers due February 19, 2026. The City of Tampa issued RFQ 26-P-00152 in March 2026 for Standard Class 125 flanged fittings (cast iron reducers, tees, outlet flanges) with a one-year award period and ten-day delivery requirement, due February 25, 2026. The code also appears in Santa Clara County's ITB for the Central Expressway Pavement Rehabilitation Project (due May 21, 2026), though that solicitation focuses on roadway construction rather than pipe fittings, suggesting misclassification.
