UNSPSC 40175302: Orifice flanges

UNSPSC 40175302 Orifice flanges (Commodity) covers cast iron and ductile iron flanged fittings, flanged outlets, reducers, tees, and related piping components that state and local water utilities and public works departments procure for water distribution system construction, rehabilitation, and maintenance. The code sees activity across municipal water services, county water authorities, and city public works departments soliciting these items through competitive sealed bids, invitations for bid, and requests for quotes for both one-time purchases and multi-year term contracts. Recent opportunities show governments buying standard Class 125 flanged fittings, mechanical joint restraining devices for ductile iron and PVC pipe, and miscellaneous water pipe assemblies that must comply with AWWA, ASTM, and ANSI standards including NSF potable water certification.

Recent activity spans Florida, Arizona, and California. The City of Tampa issued an RFQ in March 2026 for Standard Class 125 flanged fittings (cast iron flanged outlets, reducers, and tees) with a ten-day delivery requirement and one-year award term; the City of Phoenix Water Services Department issued an IFB in February 2026 for water pipe and miscellaneous fittings (including flanges, elbows, and related assemblies) across 15 product groups for a five-year contract beginning May 1, 2026, with pre-bid conference attendance and mandatory AWWA/ASTM/ANSI compliance. Palm Beach County Board of County Commissioners posted an IFB in April 2026 for mechanical joint restraining devices for ductile iron pipe (3 inches to 54 inches) and PVC pipe (3 inches to 24 inches) with a twelve-month initial term and four optional renewal periods, on a term contract basis with approximately $200,000 anticipated value over the initial year. Santa Clara County issued an ITB in April 2026 for the Central Expressway Pavement Rehabilitation Project with a May 21, 2026 response date, though this opportunity focuses primarily on roadway construction and pavement rehabilitation rather than flanged fitting procurement and represents a code misclassification.
