UNSPSC 40174902: Carbon steel pipe union

Pipe union made of carbon steel

UNSPSC 40174902 Carbon steel pipe union is a Commodity code that classifies individual threaded or flanged pipe coupling fittings used in municipal water, wastewater, and utility infrastructure. State and local governments procure these fittings as components in larger construction and rehabilitation projects involving sewer lines, water mains, and pressurized piping systems. The issuing bodies under this code are primarily county sanitation districts, public works departments, and water utilities responsible for maintaining and upgrading utility infrastructure. Work being solicited includes supply of carbon steel unions sized to match mainline and service connection pipe diameters, typically specified as part of broader repair, replacement, or extension projects for sanitary sewer and water distribution systems.

Santa Clara County is the primary recent issuer of contracts involving these fittings. County Sanitation District No. 2-3 posted an ITB (ITBRDAFY270088) on August 26, 2026 for the Structural Defect Repair Project Phase 2, a sanitary sewer rehabilitation program in the unincorporated eastern foothills that required replacement of service connection fittings including wyes in various sizes, with bids due September 17, 2026. Santa Clara County also posted an ITB (ITBRDAFY260694) on April 29, 2026 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, a comprehensive infrastructure project requiring labor, materials, and equipment for roadway and utility improvements, with bids due May 21, 2026. Activity is concentrated in California, specifically in the San Francisco Bay Area; the code shows limited recent exposure beyond this region in the available records.
