UNSPSC 40172901: Carbon steel pipe expansion joint

Pipe expansion joint made of carbon steel

UNSPSC 40172901 Carbon steel pipe expansion joint is a Commodity code that captures specialized mechanical components used in infrastructure systems where thermal stress, vibration, or system movement demands flexible connection points. Based on recent state and local solicitation activity, this code encompasses expansion joints and related piping systems installed in transportation corridors, water infrastructure, and building mechanical systems where temperature fluctuation or structural movement would otherwise cause stress failure. State and local governments procure these components as materials within larger construction and rehabilitation projects rather than as standalone line items; they are specified in bid documents for highway, transit, water, and facility projects where engineers require them to absorb movement and prevent joint failure.

The single recent opportunity on record is Santa Clara County's Central Expressway Pavement Rehabilitation Project Between Bowers Avenue and Scott Boulevard, posted April 29, 2026, with a May 21, 2026 IFB closing date. The scope, while broad (pavement recycling, asphalt overlay, curb and gutter installation, ADA improvements, traffic signal modifications, and bioretention basin installation), does not explicitly itemize expansion joint procurement; the code appears to have been applied by the issuing body as a catch-all for mechanical and utility components embedded in the project specification. The solicitation provides no project budget, incumbent vendor information, or set-aside designations. Activity under this Commodity code is sparse — the recent-opportunities block shows no additional state or local solicitations, indicating limited direct procurement volume at the state and local level or significant tagging inconsistency between the code and the actual work being solicited.
