UNSPSC 40173705: Malleable iron pipe reducing flange

Pipe reducing flange made of malleable iron

UNSPSC 40173705 Malleable iron pipe reducing flange is a Commodity code that covers specialized fittings used in sanitary sewer infrastructure rehabilitation and water conveyance systems. State and local governments procure these fittings as components in broader sewer line repair, replacement, and extension projects, typically bundled within larger infrastructure contracts managed by county sanitation districts, public works departments, and regional water agencies. The fittings serve as transition connectors in pipe networks where diameter changes are required, appearing alongside PVC, HDPE, and cast-iron pipe in mainline and service-lateral applications.

Santa Clara County has posted two recent infrastructure opportunities that touch the broader scope encompassing this code. In August 2026, Santa Clara County Sanitation District No. 2-3 issued an IFB (ITBRDAFY270088) for the Structural Defect Repair Project Phase 2, a sewer rehabilitation program with a response date of September 17, 2026; the scope includes mainline pipe replacement and service connection fittings (wyes in 4"×6", 4"×8", and 4"×10" configurations) across multiple diameters and pipe materials. In April 2026, Santa Clara County issued an IFB (ITBRDAFY260694) for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, due May 21, 2026, focused on pavement and curb work rather than pipe fittings. Geographic activity centers on California's Santa Clara County. Recent solicitations show limited direct visibility to malleable iron reducing-flange procurement; the code itself may see heavier use in routine maintenance and emergency repair work not yet posted in the recent-opportunities block, or bidders may source these fittings as pass-through components on larger fixed-price infrastructure contracts without separate itemization.
