UNSPSC 40172207: Galvanized iron pipe blind flange

Galvanized iron pipe blind flange, the galvanization is an electrochemical process by which iron is covered with other metal. The galvanization fuction is to protect the treated metal surface against corrosion.

UNSPSC 40172207 Galvanized iron pipe blind flange is a Commodity code that covers fastening and closure components used in pressurized piping systems, though recent state and local procurement activity under this code shows minimal direct solicitation for blind flanges themselves. The code appears tagged in opportunities that involve broader infrastructure rehabilitation and construction where galvanized pipe fittings and closure components may be specified as incidental materials within larger project scopes. State and local buyers tagging work under this code include county sanitation districts and county transportation authorities managing water, sewer, and roadway infrastructure projects.

Santa Clara County and its subordinate districts have posted the most recent activity. County Sanitation District No. 2-3 issued an ITB (ITBRDAFY270088) due September 17, 2026 for the Structural Defect Repair Project Phase 2, a sewer infrastructure rehabilitation program involving removal and replacement of vitrified clay pipe and cast iron with PVC and HDPE pipe, service connection fittings (wyes), precast concrete manholes, and related sewer mainline extensions in the unincorporated eastern foothills. Santa Clara County also solicited bids (ITBRDAFY260694) due May 21, 2026 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, a comprehensive pavement and roadway infrastructure project including asphalt overlay, concrete curb and gutter, ADA improvements, and traffic signal modifications. Neither solicitation explicitly foregrounds blind flanges as a line item, suggesting the code may be a secondary classification for projects incorporating piping assemblies rather than a primary commodity driver in recent state and local procurement under this code.
