UNSPSC 40174100: Pipe socketweld flanges

UNSPSC 40174100 Pipe socketweld flanges is a Class code that covers pipe fittings and connection components used in water and wastewater infrastructure projects. State and local governments procure these items primarily as part of sewer rehabilitation and water main construction programs, where they serve as critical junction points in pipe systems. The fittings are typically specified as replacement components within broader infrastructure repair or replacement contracts managed by water districts, sanitation districts, and county public works departments. Recent solicitations show demand for wyes, tees, and other transition fittings in various diameters (4-inch through 10-inch) integrated into mainline repairs and service connection replacements.

Santa Clara County is the dominant recent buyer, issuing two infrastructure ITBs between April and August 2026. County Sanitation District No. 2-3 posted ITB ITBRDAFY270088 on August 26, 2026 (due September 17, 2026) for the Structural Defect Repair Project Phase 2, a sewer mainline rehabilitation program requiring twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes as part of service connection fitting replacement across thirty-five point repairs and two mainline extensions. Santa Clara County's earlier ITB ITBRDAFY260694 (posted April 29, 2026, due May 21, 2026) for the Central Expressway Pavement Rehabilitation Project included pavement and related infrastructure work but did not explicitly name socketweld flanges in the posted summary. The code shows limited recent activity in the source; opportunities are concentrated in California's Santa Clara County jurisdiction, with no corroborating solicitations from other states or issuing-body types appearing in the most-recent-opportunities block.
