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, but recent state and local procurement activity shows little or no relevant demand under this specific classification. The opportunities tagged to this code describe industrial pipe supply, water and sewer pipe fittings, and stormwater infrastructure rehabilitation—none of which involves rupture disks as a standalone product or service line. The City of Phoenix Public Works Department and the City of Augusta, Georgia have solicited HDPE and PVC pipe, fittings, and related appurtenances; the Douglasville-Douglas County Water and Sewer Authority has requested water and sewer pipe fittings, concrete materials, valves, and manhole products; and Santa Clara County has advertised sewer mainline point repairs and pipe-burst replacements using PVC and HDPE materials. These are commodity purchases in the broader pressure-relief and piping-systems family, but they do not center on rupture disks, which are specialized safety devices designed to burst at a preset pressure threshold and protect vessels and pipelines from overpressure conditions.

Geographic activity concentrates in Georgia (Augusta, DeKalb County, Calhoun, Lavonia) and Florida (Palm Bay, Sarasota, Orange County), with secondary solicitations from California (Santa Clara County) and Arizona (Phoenix). Water and sewer utilities, municipal public works departments, and county government agencies dominate the issuing bodies. However, because the recent opportunities do not align with the rupture-disk commodity classification, this code does not present actionable intelligence for rupture-disk suppliers. A firm pursuing this category should monitor solicitations from municipal water authorities, wastewater treatment facilities, and industrial utilities in regions with aging infrastructure rehabilitation programs, as those sectors would be the primary buyers of rupture-disk assemblies—but the current posting activity does not reflect that demand under this code.
