UNSPSC 40174104: PVC plastic pipe socketweld flange

Pipe socketweld flange made of PVC plastic

UNSPSC 40174104 PVC plastic pipe socketweld flange is a Commodity code that covers rigid polyvinyl chloride piping components used in gravity-fed municipal infrastructure, particularly sanitary and stormwater systems. State and local governments procure these products as part of larger sewer and water main rehabilitation, replacement, and extension projects. The issuing bodies soliciting under this code include regional sanitation districts and county public works departments. Work solicited ranges from point repairs and pipe-burst replacements of aging vitrified clay pipe (VCP) and cast iron infrastructure to planned mainline extensions, with socketweld flanges and related fittings specified as replacement components within broader infrastructure rehabilitation scopes.

Recent activity concentrates in California, specifically Santa Clara County. The County Sanitation District No. 2-3 issued ITB ITBRDAFY270088 on August 26, 2026, for the Structural Defect Repair Project Phase 2, a sanitary sewer infrastructure rehabilitation program in the unincorporated eastern foothills with proposals due September 17, 2026. The scope includes removal and replacement of existing VCP with 326 linear feet of 6-inch PVC SDR26 pipe, 114 linear feet of 8-inch PVC SDR26, and 43 linear feet of 10-inch PVC SDR26, along with service connection fittings including 4-inch to 6-inch, 8-inch, and 10-inch wyes and 4-inch PVC SDR26 service laterals. Santa Clara County also posted ITB ITBRDAFY260694 on April 29, 2026, for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, a pavement rehabilitation project with proposals due May 21, 2026, though this solicitation does not appear to reference PVC socketweld flanges explicitly in the available summary.
