UNSPSC 40171901: Carbon steel pipe backup flange

Pipe backup flange made of carbon steel

UNSPSC 40171901 Carbon steel pipe backup flange is a Commodity code that covers pipe fittings and related mechanical components, though recent state and local solicitations show the code being applied to a broader range of water and utility infrastructure procurement. State and local governments use this category to purchase mechanical joint restraining devices, flanged fittings, pipe assemblies, and miscellaneous water system components for municipal water systems, drainage infrastructure, and pavement rehabilitation projects. The issuing bodies are predominantly city water departments, county utilities and procurement offices, and county transportation agencies—specifically the City of Phoenix Water Services Department, Palm Beach County Board of County Commissioners, City of Tampa Purchasing Department, and Santa Clara County. Recent work includes fixed-unit pricing supply contracts for mechanical joint restraining devices in various pipe diameters, Class 125 flanged fittings for municipal water distribution, and comprehensive water pipe and miscellaneous fittings supply agreements.

Activity concentrates in Florida, California, and Arizona.
