UNSPSC 31311400: Ultra violet welded UV pipe assemblies

UNSPSC 31311400 Ultra violet welded UV pipe assemblies is a Class code that captures specialized tubing and piping components for equipment and infrastructure applications in state and local operations. Recent solicitations show state and local governments buying pump tubing for water and environmental sampling equipment, as well as specialized piping components for pavement rehabilitation and related infrastructure work. The issuing bodies are county-level departments — water resources divisions, transportation authorities, and county purchasing offices — soliciting supplies and materials to support their operational and capital improvement programs.

Activity appears concentrated in the Southeast and West, with recent opportunities from Gwinnett County, Georgia (a water resources procurement for pump tubing to Avalanche Sampler equipment, RFQ due June 30, 2026) and Santa Clara County, California (a comprehensive pavement rehabilitation project including specialized tubing and piping components as part of a larger infrastructure scope, IB due May 21, 2026). The code shows limited recent state and local activity; the two opportunities posted in 2026 suggest that procurement under this code is episodic and project-driven rather than routine, tied to capital improvement cycles and equipment-replacement initiatives in water and transportation agencies.
