UNSPSC 40171603: Industrial ductile iron pipe

Pipe with a pressure rating of more than 2500 psi made of ductile iron

UNSPSC 40171603 Industrial ductile iron pipe is a Commodity code under which state and local governments procure ductile iron pipe and related fittings for water main replacement, system rehabilitation, and infrastructure rehabilitation projects. Recent solicitations show municipalities and counties purchasing 4-inch to 30-inch diameter ductile iron pipe, often specified to ANSI/AWWA C151/A21.51 standards with cement mortar lining, asphaltic coating, and Class 250 to Class 350 pressure ratings for potable water service. The issuing bodies include city water utilities (Phoenix, Tampa, Dallas, Sarasota), county water departments (Pinellas County, DeKalb County, Gwinnett County), and special-purpose water authorities (City of Lavonia). Purchases span both materials-only commodity supplies on firm-fixed or as-needed contracts and coordinated infrastructure projects pairing pipe replacement with associated work—notably Pinellas County's October 2026 RFQ for sewer and water main improvements combining 12-inch PVC sewer pipe with 6-inch ductile iron water main replacement across overlapping work areas, and the City of Tampa's September 2026 ITB for 4-inch to 6-inch ductile iron pipe with an SLBE bid discount of up to $10,000.

Geographic concentration appears heaviest in Florida (Pinellas County, Tampa, Sarasota, Palm Bay, Orange County) and Georgia (Gwinnett County, DeKalb County, Calhoun, Lavonia), with recent activity also in Arizona (Phoenix), Texas (Dallas, Southlake), and California (Santa Clara County). Representative recent opportunities include the City of Tampa's ITB 26-P-00565 (posted September 24, 2026; bids due October 16, 2026) for 1,860 linear feet of 4-inch and 2,780 linear feet of 6-inch ductile iron pipe to ANSI/AWWA C151/A21.51 standards with one-year initial term and three one-year renewal options; the City of Dallas's ID/IQ master agreement for ductile iron pipe (posted May 14, 2026; bids due June 12, 2026) serving the Water Utilities department on a five-year term with one optional six-month extension; and Gwinnett County's multiple informal written quotations for large diameter 30-inch ductile iron pipe sections, gland retainers, and tapping sleeves (September 2026, with responses due September 8–18, 2026) for water resource infrastructure. Most awards stipulate domestic manufacturing, NSF/ANSI 61 certification for potable water contact, and delivery within 14 to 60 days of purchase order issuance.
