UNSPSC 40173004: Malleable iron pipe half coupling

Pipe half coupling made of malleable iron

UNSPSC 40173004 Malleable iron pipe half coupling is a Commodity code that captures individual pipe fittings and couplings used in water and sewer infrastructure projects. Recent state and local solicitations show governments buying these components as part of broader water main replacement, sewer rehabilitation, and service connection programs. Water and sewer utilities are the primary issuing bodies, including county sanitation districts, county utility authorities, and municipal water departments. Work under this code spans both maintenance-of-supply contracts—annual or multiyear agreements for ongoing inventory replenishment—and project-specific material procurement embedded within larger infrastructure rehabilitation efforts. The County of DeKalb, Georgia and Santa Clara County Sanitation District No. 2-3 appear as repeat buyers of related water and sewer infrastructure components.

Recent activity concentrates in California and Georgia. Pinellas County, Florida posted an ITB on October 12, 2026 for coordinated sewer and water main improvements including approximately 500 linear feet of 12-inch PVC sanitary sewer pipe and 6,800 linear feet of 6-inch water main replacement with service components (response October 13, 2026, final bids November 5, 2026). Santa Clara County Sanitation District No. 2-3 issued an ITB in August 2026 for the Structural Defect Repair Project Phase 2, involving removal and replacement of vitrified clay and cast iron pipe with PVC and HDPE across multiple diameters and service connection fittings (response September 17, 2026). The City of Marietta, Georgia solicited water service saddles, couplings, clamps, and valves under annual contract BL121-26 (due September 22, 2026), and the County of DeKalb, Georgia issued a three-year multiyear ITB for quick insertion valves and tapping sleeves (due August 27, 2026).
