UNSPSC 40171704: Ductile iron pipe adapter

Pipe adapter made of ductile iron

UNSPSC 40171704 Ductile iron pipe adapter is a Commodity code that encompasses specialized fittings and connectors used in water and sewer infrastructure rehabilitation projects. State and local governments procure these adapters—including bell-and-spigot configurations, MJS (mechanical joint systems), and connection fittings in various diameters—to bridge incompatible pipe materials and standards during mainline replacement, extension, and repair work. The buying is driven by aging water and sanitary sewer systems requiring replacement of vitrified clay pipe, cast iron, galvanized, and substandard PVC with modern materials such as high-density polyethylene and PVC SDR26. Issuing bodies span county utilities and sanitation districts, with Pinellas County, Florida; Santa Clara County and its Sanitation District No. 2-3 in California; and Gwinnett County, Georgia appearing as recent buyers. These are infrastructure-focused jurisdictions managing regional or countywide water and sewer operations, typically soliciting through formal competitive procurement.

Recent activity centers in Florida and California, with secondary representation in Georgia. Pinellas County, Florida issued a two-step IFB (Solicitation 260652ITBC, due November 5, 2026) for coordinated sewer and water main improvements including approximately 500 linear feet of 12-inch sanitary sewer pipe replacement and 6,800 linear feet of 6-inch water main replacement, with service connections and fittings as supporting scope. Santa Clara County's Sanitation District No. 2-3 posted an IFB (ITBRDAFY270088, due September 17, 2026) for a structural defect repair project involving removal and replacement of vitrified clay and cast iron pipe with PVC and HDPE, including service connection wyes in 4-inch through 10-inch ranges. Gwinnett County, Georgia issued an informal written quotation (PE77023NONST2026000000634, due June 15, 2026) for six 48-inch MJS adapters with gaskets and diapers. These opportunities reflect steady demand from utilities managing mainline rehabilitation and sewer extension projects where adapter procurement is bundled with broader infrastructure contracts or purchased as standalone components for inventory or specific improvements.
