UNSPSC 40172900: Pipe expansion joints

UNSPSC 40172900 Pipe expansion joints is a Class code covering the supply of mechanical devices that accommodate thermal and structural movement in piping systems, though state and local governments procure these components primarily as subordinate materials within larger infrastructure rehabilitation and construction projects rather than as standalone pipe-fitting purchases. The code captures expansion joints specified in bridge, highway, water infrastructure, and building system upgrades where temperature fluctuations, pressure changes, or structural settlement require compensating joints to prevent pipe failure. State and local issuing bodies soliciting under this code include county transportation departments, municipal water and wastewater utilities, and city public works divisions managing aging or newly constructed infrastructure systems.

Santa Clara County posted ITB ITBRDAFY260694 on April 29, 2026, for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, with bids due May 21, 2026. While the primary scope centers on pavement rehabilitation, hot mix asphalt overlay, curb and gutter installation, and traffic signal modifications, the project specifications would incorporate pipe expansion joints as part of any stormwater or drainage system work embedded in the corridor improvements. The solicitation requires physical bid submission to the County Clerk of the Board of Supervisors at the County Government Center in San Jose, California, with a 142-working-day completion timeline. No project budget or set-aside designations were disclosed. Recent state and local activity under this code is limited; expansion joints appear most commonly as materials line-items in regional road and utility rehabilitation RFPs rather than as standalone procurement vehicles.
