UNSPSC 31311312: Copper bolted pipe assemblies

UNSPSC 31311312 Copper bolted pipe assemblies is a Commodity code that describes supplies of copper tubing and related piping products for water, sewer, and industrial infrastructure projects. State and local governments procure under this code primarily as components of larger water main replacement, stormwater rehabilitation, and municipal utility projects rather than as standalone assemblies. The issuing bodies are predominantly municipal water and utilities departments—the City of Phoenix Water Services Department and City of Phoenix Public Works Department, Orange County Florida utilities, Barnwell County South Carolina, and the Alameda County Water District—along with county public works agencies managing outfall and stormwater pipe replacement. Work is being solicited as both as-needed supply contracts for inventory and as materials within fixed-term construction projects.

Recent activity concentrates in Florida and Arizona, with secondary activity in California and South Carolina.
