UNSPSC 31311302: Carbon steel bolted pipe assemblies

UNSPSC 31311302 Carbon steel bolted pipe assemblies, a Commodity code, spans industrial piping, fabrication services, and pipe materials that state and local governments procure for water infrastructure, wastewater systems, stormwater drainage, and utility construction projects. Recent state and local solicitations show demand across three distinct segments: supplier contracts for bulk pipe stock (carbon steel, stainless steel, reinforced concrete, HDPE, and corrugated metal pipe in multiple diameters), fabrication and welding services for on-site assembly and repair of steel components, and just-in-time material coordination for active construction. Issuing bodies include state departments (California, Georgia), county water and wastewater agencies (Orange County Florida, Gwinnett County Georgia, Broward County Florida, Pima County Arizona), city public works and utilities departments (Phoenix, Palm Bay, Lawrenceville, Tucson, Lavonia), and independent water authorities (Notla Water Authority). Procurement preferences appear in several jurisdictions—Orange County Florida applies Service Disabled Veteran Business tiered discounts; Broward County and Pima County deploy Small Business Enterprise and Disadvantaged Business Enterprise set-asides or aspirational goals; Lavonia Georgia mandates 4.0% minority and women-owned business participation targets. Recent opportunities reflect robust infrastructure investment in water system upgrades, stormwater replacement, and sewer line modernization across the Southeast and West.
