UNSPSC 40173200: Pipe long weldneck flanges

UNSPSC 40173200 Pipe long weldneck flanges is a Class code that spans pipe fittings and connection components used in water and wastewater infrastructure repair and replacement projects. State and local governments procure under this code primarily through municipal water and sanitation districts, county public works departments, and regional utility authorities that manage sewer and potable water systems. The actual work involves supply and installation of flanged pipe components during mainline rehabilitation, pipe replacement, and infrastructure extension projects—notably including wyes, fittings, and connection assemblies that join sections of PVC, HDPE, and replacement piping in sanitary sewer systems and potable water lines.

Santa Clara County accounts for recent visible activity under the code, with at least two active projects issued by county sanitation districts and the county public works department. County Sanitation District No. 2-3 issued ITB ITBRDAFY270088 on August 26, 2026, with proposals due September 17, 2026, for the Structural Defect Repair Project Phase 2, which includes removal and replacement of service connection fittings—twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes—as part of a sewer mainline rehabilitation program in the unincorporated eastern foothills. Santa Clara County also issued ITB ITBRDAFY260694 on April 29, 2026, with bids due May 21, 2026, for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, a broader pavement and utility infrastructure project with a 142 working day completion timeline. Both opportunities require physical bid delivery to the County Government Center in San Jose, California. The code shows limited recent activity in the available opportunities dataset, with no visible solicitations from other states or jurisdictions at this time.
