UNSPSC 40173200: Pipe long weldneck flanges

UNSPSC 40173200 Pipe long weldneck flanges is a Class code that describes mechanical pipe fittings and restraining devices purchased by state and local governments for water distribution, wastewater infrastructure, and general utility maintenance. Recent solicitations show that state and local buyers source a range of flanged fittings and joint restraint equipment — cast iron flanged fittings in multiple sizes and configurations, ductile iron pipe restraining devices, polyvinyl chloride pipe restraining devices with accessory packages, and miscellaneous water pipe components including flanges, bushings, couplings, and elbows. Issuing bodies span municipal water and utility departments, county boards of supervisors, and city purchasing departments. Palm Beach County, the City of Phoenix Water Services Department, the City of Tampa Purchasing Department, and Santa Clara County have all posted opportunities within the past four months.

Recent procurement activity appears most concentrated in Florida and California. The City of Phoenix Water Services Department issued an IFB for water pipe and miscellaneous fittings (15 product groups including flanges) with a five-year term commencing May 1, 2026; Palm Beach County Board of County Commissioners posted an IFB for mechanical joint restraining devices on a term-contract basis with an anticipated contract value of $200,000 over twelve months and response due June 4, 2026; the City of Tampa issued an RFQ for Standard Class 125 flanged fittings with responses due February 25, 2026; and Santa Clara County posted an ITB for the Central Expressway Pavement Rehabilitation Project (which includes miscellaneous utility and infrastructure components) with a May 21, 2026 response deadline. Palm Beach County's solicitation explicitly recognizes Small Business Enterprise certified bidders with a ten percent price preference when bids fall within ten percent of the lowest non-SBE bid, and a five percent local preference for bidders with a permanent place of business in Palm Beach County or the Glades. The City of Phoenix requires DBE compliance under 49 C.F.R. Part 26.
