UNSPSC 40173903: Ductile iron pipe rupture disk

Pipe rupture disk made of ductile iron

UNSPSC 40173903 Ductile iron pipe rupture disk is a Commodity code. State and local governments purchase industrial and potable water system pipe materials—including HDPE, PVC, ductile iron water main, and associated fittings, couplings, valves, and appurtenances—predominantly through annual supply contracts and as-needed purchase agreements. Recent solicitations show procurement focused on inventory stocking for water and sewer infrastructure maintenance, main replacements, and drainage system rehabilitation; the code's nominal focus on rupture disks does not reflect the broader materials-supply activity actually being solicited. Issuing bodies include city public works departments, county water and sewer authorities, and special-purpose water districts. Cities of Phoenix and Sarasota, DeKalb County (Georgia), Calhoun (Georgia), and the Douglasville-Douglas County Water and Sewer Authority appear in multiple recent notices, signaling sustained demand from these jurisdictions.

Recent activity concentrates in Arizona, Florida, and Georgia. The City of Phoenix Public Works Department issued back-to-back IFBs for industrial pipe and fittings supply (IFB 27-SW-0447 due September 30, 2026 and IFB 26-SW-0379 due August 12, 2026), both three-year terms with two optional one-year extensions, covering HDPE and PVC pipe from 0.75 to 24 inches with fittings, glue, and hand tools; the City of Augusta, Georgia solicited various HDPE pipe, coupling, and end sections for stormwater installation (ITB 27-116, due September 29, 2026, one year with four optional one-year renewals); and the Douglasville-Douglas County Water and Sewer Authority requested annual water and sewer pipe fittings and related materials (IFB 327, due October 7, 2026). DeKalb County, Georgia sought quick insertion valves and tapping sleeves (ITB 2026-034-ITB, due August 27, 2026, three-year multiyear contract). Contracts typically require 24- to 60-day delivery, local inventory maintenance, firm fixed pricing for the full term, and compliance with DBE participation goals or small business plans where federal funds apply.
