UNSPSC 40182306: Seamless steel tube assembly

Seamless tube assembly made of steel

UNSPSC 40182306 Seamless steel tube assembly, a Commodity code, covers the supply of pipes and tubing systems for infrastructure projects, though recent state and local opportunities in this category show wide variance in material specifications and application. State and local governments soliciting under this code are primarily county departments managing water resources and transportation infrastructure. Santa Clara County and Gwinnett County represent the issuing bodies in recent postings, both procuring through county purchasing and department-specific channels rather than through state-level cooperative vehicles. The scope of work ranges from specialized stormwater conveyance systems — reinforced concrete pipe, high-density polyethylene pipe, and corrugated metal pipe in multiple diameter and corrugation specifications — to broader pavement rehabilitation projects where pipe assembly may be an incidental component rather than the primary deliverable.

Recent activity concentrates in California and Georgia. Gwinnett County Board of Commissioners issued Invitation to Bid BL079-26 on April 16, 2026, seeking purchase of stormwater pipe on an annual contract for the Department of Water Resources, with sealed bids due May 19, 2026, covering reinforced circular concrete pipe from 15" to 72" diameter, high-density polyethylene pipe from 12" to 24" diameter, and corrugated metal full round pipe in multiple corrugation specifications, with delivery required within fourteen days of order placement on an F.O.B. Destination basis and an initial four-year term followed by four optional 12-month renewal periods. Santa Clara County issued Invitation to Bid ITBRDAFY260694 on April 29, 2026, for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, with bids due May 21, 2026, encompassing partial depth recycling, hot mix asphalt overlay, pavement repairs, and Portland cement concrete curb and gutter installation among multiple disciplines, with 142 working days to completion. The Gwinnett County solicitation represents a closer match to the code's nominal scope and signals sustained demand for stormwater pipe supply on multi-year standing contracts.
