UNSPSC 40174906: Malleable iron pipe union

Pipe union made of malleable iron

UNSPSC 40174906 Malleable iron pipe union, a Commodity code, represents fittings and connectors used in pressurized and gravity-flow piping systems for water and wastewater infrastructure. State and local governments procure these components as replacement parts and new-installation materials in sewer mainline rehabilitation, water distribution upgrades, and sanitary system extensions. The code sees activity from county sanitation districts, county transportation and public works departments, and municipal water and wastewater authorities. Malleable iron unions appear in bid packages alongside PVC, HDPE, and cast iron pipe; they are typically specified where pipe sections require removable connections or where expansion and contraction demand flexible joinery.

Recent activity centers in California, where Santa Clara County issued two significant infrastructure solicitations in 2026. County Sanitation District No. 2–3 posted an ITB (ITBRDAFY270088) on August 26, 2026 for the Structural Defect Repair Project Phase 2, due September 17, 2026, which includes removal and replacement of service connection fittings—twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes—as part of a broader sewer mainline rehabilitation scope. Santa Clara County also issued an ITB (ITBRDAFY260694) on April 29, 2026 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, due May 21, 2026, with pavement and drainage work that may require incidental pipe fittings. The source reveals no other recent state or local opportunities under this code; activity appears concentrated in California water and sanitation infrastructure projects with relatively long project timelines (65 to 142 working days).
