UNSPSC 31311503: Hastalloy X welded or brazed pipe assemblies

UNSPSC 31311503 Hastalloy X welded or brazed pipe assemblies is a Commodity code. State and local governments buying under this code procure industrial piping systems including HDPE and PVC pipe stock, fittings (elbows, couplings, tees, wyes), bends at various angles, end sections, and associated materials for stormwater drainage, natural gas infrastructure, electrical conduit, and airport operations on an as-needed basis. Recent solicitations show demand for pipe stock ranging from 0.75 inches to 36 inches in diameter, supplied with firm pricing and fast turnaround (24–48 hours typical for airport and municipal utility orders). Cities, county utilities, and public universities are the primary issuing bodies, with contracts spanning one to three years, often with one-year renewal options and price-escalation caps of three percent maximum.

The City of Phoenix Public Works Department dominates recent activity, posting identical-scope IFBs for industrial pipe and fittings supply in August 2026 (IFB 26-SW-0379, due August 12) and September 2026 (IFB 27-SW-0447, due September 30), both covering three-year terms with two optional one-year extensions for Phoenix Sky Harbor International Airport and two other Phoenix municipal airports. Lubbock Power & Light (a Texas municipal utility) requested 3,000 feet of 15 KV outdoor aluminum pipe cable in a September 2026 quote request (26-7014-ELD, due September 25). The City of Augusta, Georgia issued an ITB on September 10, 2026 (27-116, due September 29) for HDPE pipe, couplings, and end sections for stormwater management. The City of Lawrenceville, Georgia solicited natural gas pipe and materials for a DOT project corridor (bid due July 23, 2026). Geographic activity concentrates in Arizona, Georgia, Texas, and Florida, with smaller representation in California. Issuing bodies enforce DBE participation plans, E-Verify compliance, local-business preferences where applicable, and MBE/WBE requirements. Contractors must maintain local inventory, provide firm fixed pricing across contract terms, deliver within specified windows, and maintain emergency after-hours availability for municipal and utility customers.
