UNSPSC 40175003: Stainless steel pipe weldneck flange

Pipe weldneck flange made of stainless steel

UNSPSC 40175003 Stainless steel pipe weldneck flange, a Commodity code, shows minimal recent state and local procurement activity aligned with its nominal scope. The recent opportunities posted under this code comprise water infrastructure, mechanical joint restraining devices, cast iron flanged fittings, and pavement rehabilitation projects—none of which center on stainless steel weldneck flanges as the primary deliverable. The Santa Clara County pavement rehabilitation IFB (ITBRDAFY260694, due May 21, 2026) involves asphalt overlay, concrete curb and gutter, and traffic infrastructure but does not isolate flange procurement. The Palm Beach County mechanical joint restraining device IFB (#26-038/RR, due June 4, 2026) covers restraining devices for ductile iron and PVC pipe but does not address stainless steel flanges. The City of Tampa RFQ (26-P-00152, due February 25, 2026) seeks cast iron Class 125 flanged fittings—a distinct product category. The City of Phoenix five-year IFB (IFB260217, due February 19, 2026) for water pipe and miscellaneous fittings includes flanges as one of 15 product groups but does not specify stainless steel or weldneck construction.

The code sees activity concentrated in Florida (Palm Beach County and City of Tampa) and Arizona (City of Phoenix), with one California jurisdiction (Santa Clara County). Issuing bodies are municipal water services departments and county infrastructure agencies rather than a broad mix of state or school district buyers. The mismatch between the code's nominal product—stainless steel weldneck flanges—and the recent opportunities tagged under it suggests this code receives limited relevant procurement volume in the state and local market, or that issuers are using the code to classify broader water infrastructure and fitting purchases that may include but are not centered on stainless steel pipe flanges. Firms pursuing this code should verify actual procurement demand through direct outreach to water utilities and county infrastructure departments in active states rather than relying on posted UNSPSC classifications.
