UNSPSC 40173901: Carbon steel pipe rupture disk

Pipe rupture disk made of carbon steel

UNSPSC 40173901 Carbon steel pipe rupture disk is a Commodity code with little recent activity directly aligned to its nominal scope. The recent state and local opportunities tagged to this code center instead on industrial pipe supply, water main materials, sewer and stormwater piping systems, and miscellaneous plumbing and hydraulic fittings—broadly industrial piping infrastructure rather than pressure-relief rupture disks. Cities and counties are procuring ductile iron pipe, PVC pipe, mechanical joint fittings, gate valves, fire hydrants, air release valves, and manhole components for water treatment facilities, water main relocation projects, sewer system upgrades, and stormwater rehabilitation along transportation corridors. Issuing bodies span city public works departments (Phoenix, Sarasota, Palm Bay, Dallas), county utilities and transportation authorities (Orange County, Gwinnett County), and smaller municipal water systems (Calhoun, Lavonia). The code does not show a clear pattern of rupture disk procurement; rather, the tag appears to reflect a broader industrial piping materials classification that encompasses multiple commodity lines.

Recent activity concentrates in Florida and Georgia. The City of Phoenix Public Works Department posted an IFB on July 8, 2026 for industrial pipe, fittings, and equipment with responses due August 12, 2026, establishing a three-year supply agreement with two optional one-year extensions. The City of Sarasota issued an ITB for potable water main materials on June 29, 2026 for the Small AC Water Main Replacement–FY24 project, requiring conformance to an approved manufacturers list and delivery within ninety days. Orange County, Florida procured sewer pipes and fittings through a sealed IFB with an estimated five-year spending total of approximately $28.7 million, with Service Disabled Veteran Business preference applied. The City of Calhoun, Georgia requested bids for water main relocation supplies including ductile iron mains and PVC piping due June 18, 2026. These procurements are large-volume, multi-year supply agreements with firm pricing, approved-equal provisions, and aggressive delivery timeframes—characteristics typical of municipal infrastructure maintenance contracts. The code shows sparse activity for actual rupture disk procurement and may warrant verification against the jurisdictions' actual commodity classifications.
