UNSPSC 40174101: Carbon steel pipe socketweld flange

Pipe socketweld flange made of carbon steel

UNSPSC 40174101 Carbon steel pipe socketweld flange is a Commodity code that describes specialized pipe connection components, though recent state and local solicitations show significant misalignment between the code's nominal scope and actual procurement activity. The four most recent opportunities tagged to this code involve mechanical joint restraining devices for water distribution systems, standard class flanged fittings for municipal use, water pipe and miscellaneous fittings for a five-year supply contract, and pavement rehabilitation work — none of which directly align with carbon steel socketweld flanges. Palm Beach County Board of County Commissioners issued an IFB in April 2026 for mechanical joint restraining devices for ductile iron and PVC pipe; the City of Tampa issued an RFQ in March 2026 for cast iron flanged fittings; the City of Phoenix Water Services Department issued an IFB in February 2026 for water pipe and miscellaneous fittings across 15 product groups on a five-year term; and Santa Clara County issued an ITB in April 2026 for a comprehensive pavement rehabilitation project that incidentally includes some pipe-related work. The issuing bodies span cities, counties, and large water utilities across Florida, Arizona, and California.

The geographic spread centers on Florida (Palm Beach County and City of Tampa), Arizona (City of Phoenix), and California (Santa Clara County), reflecting activity among mid-to-large municipal procurement offices and county authorities. The Palm Beach County IFB for mechanical joint restraining devices due June 4, 2026, anticipates $200,000 over the initial twelve-month contract term and offers a ten percent price preference for Small Business Enterprise bidders. The City of Phoenix five-year water pipe and fittings contract, with sealed offers due February 19, 2026, requires bidders to have five years' operating history, maintain local inventory, and comply with DBE requirements. The mismatch between the code's name and the actual work being solicited suggests this code may receive infrequent or misclassified tagging in state and local procurement systems, making it an unreliable indicator of genuine carbon steel socketweld flange demand.
