UNSPSC 40174105: CPVC plastic pipe socketweld flange

Pipe socketweld flange made of CPVC plastic

UNSPSC 40174105 CPVC plastic pipe socketweld flange is a Commodity code that captures chlorinated polyvinyl chloride (CPVC) piping components used in municipal water, wastewater, and infrastructure rehabilitation projects. State and local governments procure these flanges as part of larger sanitary sewer mainline repairs, pipe replacements, and system extensions. The work spans county sanitation districts, municipal water and sewer authorities, and county public works departments undertaking infrastructure rehabilitation. Recent solicitations show that CPVC socketweld flanges appear alongside PVC SDR26 pipe, HDPE pipe, and precast concrete components in comprehensive sewer system modernization and structural defect repair programs.

Santa Clara County has generated the most visible recent activity under this code. The County Sanitation District No. 2-3 Structural Defect Repair Project Phase 2 (ITB ITBRDAFY270088, due September 17, 2026) called for removal and replacement of vitrified clay pipe with PVC SDR26, HDPE pipe bursting, and service connection fittings including wyes in Santa Clara County's unincorporated eastern foothills, with a sixty-five working day completion window. A second recent opportunity from Santa Clara County — the Central Expressway Pavement Rehabilitation Project Between Bowers Avenue and Scott Boulevard (ITB ITBRDAFY260694, due May 21, 2026) — encompassed pavement rehabilitation, PCC curb installation, and traffic infrastructure work but does not explicitly reference socketweld flange procurement. Activity appears concentrated in California, particularly Santa Clara County, though the source provides limited geographic breadth to characterize the code's statewide or regional pattern.
