UNSPSC 40173003: Forged steel pipe half coupling

Pipe half coupling made of forged steel

UNSPSC 40173003 Forged steel pipe half coupling is a Commodity code that covers pipe fittings and couplings for water and wastewater infrastructure projects. State and local governments procure these components as part of broader sewer and water main replacement, rehabilitation, and extension work. The issuing bodies soliciting under this code span county utility authorities, county sanitation districts, and municipal water departments. Recent opportunities show that these fittings are specified within larger infrastructure rehabilitation contracts where they serve as connection points and branch connections in gravity and pressurized piping systems.

Recent activity appears concentrated in California and Georgia. Santa Clara County Sanitation District No. 2-3 posted an ITB in August 2026 for the Structural Defect Repair Project Phase 2, which specifies removal and replacement of service connection fittings including 4"×6", 4"×8", and 4"×10" wyes as part of a sewer mainline rehabilitation scope covering vitrified clay pipe replacement and pipe bursting work with a sixty-five working day completion window. Pinellas County, Florida issued an IFB in October 2026 for coordinated sewer and water main improvements in the City of Seminole, including approximately 500 linear feet of 12-inch PVC sanitary sewer pipe and 6,800 linear feet of 6-inch water main replacement using both open-cut and horizontal directional drilling methods, with qualification submittal due October 13, 2026 and final bids due November 5, 2026. The City of Marietta, Georgia and DeKalb County, Georgia have posted separate annual supply contracts for water service couplings and quick insertion valves and related fittings. These opportunities indicate that half couplings and similar fittings are sourced as components within unit-price and lump-sum infrastructure contracts rather than as standalone material purchases, with contract terms ranging from sixty-five working days to 380 consecutive calendar days.
