UNSPSC 40173606: Malleable iron pipe reducing coupling

Pipe reducing coupling made of malleable iron

UNSPSC 40173606 Malleable iron pipe reducing coupling, a Commodity code, addresses water and sanitary sewer infrastructure components that state and local governments procure for mainline and service connection work. Recent solicitations show state and local buying agencies acquiring reducing couplings, service saddles, compression couplings, quick insertion valves, and related fittings as discrete components within larger water main replacement and sewer rehabilitation projects. These components are commonly bundled with pipe, valves, wyes, and flushing inlets in competitive-bid infrastructure contracts issued by county water districts, sanitation authorities, and municipal utilities. The work is procurement-focused rather than design-build; issuing bodies specify material sizes, grades (PVC SDR26, HDPE, VCP), and quantity requirements upfront, with contractors and equipment suppliers bidding unit or lump-sum rates for supply and installation.

Recent activity spans California and Georgia, with two large-scale sewer and water infrastructure projects from Santa Clara County and Pinellas County, Florida, and component supply contracts from the City of Marietta and DeKalb County in Georgia. Pinellas County, Florida issued an ITB (Solicitation 260652ITBC) on October 12, 2026 for the Ridgewood Estates Sewer Improvements and 82nd Avenue & 113th Street Water Main Improvements projects, with qualification submittals due October 13, 2026 and final bids due November 5, 2026, requiring replacement of approximately 6,800 linear feet of 6-inch water main and 500 linear feet of 12-inch sanitary sewer pipe along with service fittings and gate valves. Santa Clara County Sanitation District No. 2-3 issued an ITB (Solicitation ITBRDAFY270088) on August 26, 2026 for the Structural Defect Repair Project Phase 2, with bids due September 17, 2026, specifying removal and replacement of vitrified clay pipe with PVC pipe in multiple diameters, pipe bursting with HDPE, and twenty-seven 4"×6" wyes and additional service connection fittings. The City of Marietta, Georgia posted an ITB (Solicitation PE77023NONST2027000000714) on August 26, 2026 for water service saddles, couplings, clamps, and valves under annual contract, with bids due September 22, 2026. DeKalb County, Georgia issued an ITB (Solicitation PE64400NONST2027000000268) on July 27, 2026 for quick insertion valves under a three-year multiyear contract, with bids due August 27, 2026.
