UNSPSC 40173100: Pipe lapjoint flanges

UNSPSC 40173100 Pipe lapjoint flanges, a Class code, covers flanged pipe fittings and joint restraining devices that state and local governments procure for water infrastructure, municipal utilities, and public works projects. Recent solicitations show state and local agencies buying cast iron and ductile iron flanged fittings, mechanical joint restraining devices for water pipes, standard class flanged reducers and tees, and comprehensive water pipe and miscellaneous fitting assemblies that conform to AWWA, ASTM, and ANSI standards. The code draws activity from municipal utilities and water services departments as primary issuing bodies, alongside county water authorities and transportation agencies. Cities such as Tampa, Phoenix, and Santa Clara County post regularly under this code, with Palm Beach County issuing term contracts for mechanical joint restraining devices.

Geographic activity concentrates in Florida and Arizona, with recent high-visibility solicitations from the City of Phoenix Water Services Department, Palm Beach County Board of County Commissioners, the City of Tampa Purchasing Department, and Santa Clara County. Representative opportunities include the City of Phoenix Water Services Department's five-year IFB for water pipe and miscellaneous fittings (15 product groups, sealed offers due February 19, 2026); Palm Beach County's IFB for mechanical joint restraining devices on a term contract basis (Lot 1 for ductile iron pipe sizes 3 to 54 inches, Lot 2 for PVC pipe 3 to 24 inches, sealed bids due June 4, 2026, anticipated contract value $200,000 over twelve months); the City of Tampa's RFQ for Standard Class 125 Flanged Fittings (five line items, quotes due February 25, 2026); and Santa Clara County's Central Expressway Pavement Rehabilitation Project ITB (comprehensive infrastructure including curb, gutter, and roadway components, bids due May 21, 2026). Contractors must typically demonstrate five years in operation, maintain local inventory with next-day delivery capability, carry Commercial General Liability and Workers' Compensation insurance, and comply with state and local SBE and local-preference set-asides where applicable.
