UNSPSC 40173703: Ductile iron pipe reducing flange

Pipe reducing flange made of ductile iron

UNSPSC 40173703 Ductile iron pipe reducing flange, a Commodity code, covers specialty pipe fittings and connectors used in municipal water and sewer infrastructure rehabilitation projects. State and local governments procure these components as part of larger sanitary sewer mainline repairs, pipe replacement programs, and sewer system extensions. The code sees activity from county sanitation districts and county public works departments managing aging infrastructure rehabilitation across their service areas.

Santa Clara County has posted two representative opportunities under this code recently. County Sanitation District No. 2-3 issued ITB ITBRDAFY270088 in August 2026 for the Structural Defect Repair Project Phase 2, a sewer infrastructure rehabilitation program in the unincorporated eastern foothills requiring removal and replacement of vitrified clay pipe with PVC and HDPE pipe, along with service connection fittings including 4"×6", 4"×8", and 4"×10" wyes; bids were due September 17, 2026.

Both solicitations required physical bid delivery to the County Government Center in San Jose. The code shows limited recent activity in the posted opportunities block; no other states or jurisdictions appear in the source material.
