UNSPSC 40173403: Cast iron pipe plate flange

Pipe plate flange made of cast iron

UNSPSC 40173403 Cast iron pipe plate flange is a Commodity code that covers flanged cast iron pipe components used in water and wastewater infrastructure rehabilitation. State and local governments buy these components primarily as replacement parts in sanitary sewer mainline repair and pipe-replacement projects, where cast iron segments are removed and replaced with modern materials like PVC and HDPE. The work typically spans point repairs to existing trunk lines, pipe-bursting operations that require coupling and transition fittings, and service connection modifications. Issuing bodies soliciting under this code are predominantly special-purpose sanitation districts and county public works departments managing aging sewer infrastructure in suburban and foothills areas.

Santa Clara County has posted the most recent relevant activity: County Sanitation District No. 2-3 released an ITB (ITBRDAFY270088) on August 26, 2026, due September 17, 2026, for the Structural Defect Repair Project Phase 2 in the unincorporated eastern foothills, which includes pipe-bursting of existing 6-inch cast iron segments totaling 1,080 linear feet and replacement of cast iron service connection fittings. A second Santa Clara County solicitation, the Central Expressway Pavement Rehabilitation Project (ITBRDAFY260694), posted April 29, 2026, due May 21, 2026, did not reference cast iron flanged components in its scope and appears peripherally tagged to this code; it focused on asphalt, concrete, and traffic infrastructure along the expressway corridor. Geographic activity is concentrated in California, specifically Santa Clara County's water and sanitation districts. No other states or jurisdictions appear in the recent-opportunities block.
