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 covering specialized industrial piping components and related materials that state and local governments procure primarily for water infrastructure, stormwater systems, and municipal utility networks. Recent solicitations show state and local buyers purchasing ductile iron pipe fittings, nipples, and appurtenances as part of larger water main replacement, treatment facility upgrades, and outfall rehabilitation projects rather than as standalone rupture disks. The issuing bodies span city water utilities (Phoenix, Sarasota, Calhoun, Palm Bay, Dallas), county water resources departments (Gwinnett County), and county environmental management agencies (Orange County). Cities pursue both as-needed supply contracts and project-specific material bids; Gwinnett County's Department of Water Resources and Orange County's Utilities Division are repeat participants in the recent opportunity set.

Activity concentrates in Florida and Georgia, with recent opportunities posted by Phoenix, Arizona; Sarasota, Calhoun, and Palm Bay, Florida; Gwinnett County and Calhoun, Georgia; and Orange County, Florida. Representative solicitations include the City of Phoenix Public Works Department IFB 26-SW-0379 (posted July 8, 2026, due August 12, 2026) for a three-year as-needed supply of industrial pipe, fittings, and appurtenances including HDPE and PVC pipe with 24- to 48-hour delivery requirements; the City of Sarasota ITB 26-31JS (posted June 29, 2026, deadline passed) for materials-only supply of pipe, fittings, and appurtenances conforming to the City's Potable Water Approved Material List; and Gwinnett County's Informal Written Quotation 128859 (posted April 17, 2026, due April 23, 2026) for ductile iron pipe nipples with polyethylene coating in flange-connection configurations. Orange County, Florida issued a five-year sewer pipes and fittings IFB (Y26-126, updated January 22, 2026) with an estimated five-year spending total of approximately $28.7 million, spanning 56 line items of PVC and ductile iron pipes, fittings, valves, and manhole components. Most recent opportunities emphasize rapid delivery capability, compliance with approved material lists or standards (AWWA, ANSI), and fixed pricing structures, reflecting the role of rupture disks and related fittings within planned infrastructure replacement cycles rather than emergency stockpiling demand.
