UNSPSC 31311700: Bonded pipe assemblies

UNSPSC 31311700 Bonded pipe assemblies is a Class code describing industrial piping systems and components—including PVC and ductile iron pipes, HDPE piping, fittings, couplings, elbows, valves, and related assembly hardware—that state and local governments procure for water infrastructure, sewer systems, stormwater management, and drainage applications. State and local issuing bodies soliciting under this code span water utilities departments, county infrastructure authorities, city public works and water utilities divisions, and county environmental or utilities agencies. Procurement methods include IFBs, ITBs, and RFPs for both as-needed supply contracts and project-specific construction work. Recent opportunities show demand for industrial pipe supply on three-year or five-year master agreements with as-needed ordering and rapid delivery requirements (24 to 48 hours), alongside project-level work for pipe replacement, rehabilitation, and stormwater system restoration.
