UNSPSC 40173310: Ductile iron pipe nipple

A piece of externally threaded tube used to join two tubes and made from ductile iron.

UNSPSC 40173310 Ductile iron pipe nipple is a Commodity code that covers small-diameter threaded or flanged iron pipe fittings and connecting components used in water distribution, wastewater, drainage, and industrial piping systems. State and local governments procure these fittings as repair and maintenance components, bundled within larger infrastructure projects or as standing parts inventory for water utilities, public works departments, and transit authorities. The code sees solicitation from municipal water and sewer utilities, county public works offices, and city infrastructure maintenance programs across multiple jurisdictions.

Recent posted opportunities under this code are sparse. Santa Clara County issued an ITB (ITBRDAFY260694) on April 29, 2026 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard in San Jose, California, with a bid-opening deadline of May 21, 2026; however, that solicitation's primary scope covers pavement recycling, asphalt overlay, concrete curb and gutter work, ADA improvements, and traffic signal modifications—not pipe fittings. The listing under this Commodity code appears to be a tagging mismatch, as no discrete ductile iron pipe nipple procurement is described in the opportunity details. No budget or award value is disclosed for the Santa Clara project. The scarcity of targeted opportunities under this code suggests either limited recent independent solicitations for pipe fittings alone (most procurement bundling them into larger construction or utility contracts) or minimal state and local activity in the current window.
