UNSPSC 40173302: Carbon steel pipe nipple

Pipe nipple made of carbon steel

UNSPSC 40173302 Carbon steel pipe nipple is a Commodity code that covers small-diameter steel pipe fittings and connectors used in pressurized piping systems, though recent state and local procurement activity under this code shows limited direct relevance. The single recent opportunity on record involves Santa Clara County Sanitation District No. 2-3's Structural Defect Repair Project Phase 2, an ITB solicitation posted August 26, 2026, with response due September 17, 2026. That project scope centers on sewer infrastructure rehabilitation using PVC and HDPE pipe for mainline replacements and extensions, with service connection fittings specified as PVC wyes rather than carbon steel nipples. The code tagging appears to be a misclassification; the work is predominantly gravity-flow sanitary sewer construction, not pressurized piping systems where carbon steel nipples are typically specified. A second recent opportunity from Santa Clara County, the Central Expressway Pavement Rehabilitation Project (ITB due May 21, 2026), involves roadway pavement, curbing, and traffic infrastructure work with no relevance to carbon steel pipe fittings or nipples.

State and local procurement activity under UNSPSC 40173302 shows no substantive recent opportunities aligned with carbon steel pipe nipple supply or installation. The available records do not support characterization of issuing-body mix, geographic concentration, or representative solicitations for this specific commodity. If pursuing work under this code, direct outreach to water utilities, wastewater treatment authorities, and municipal public works departments in California and other high-infrastructure-activity states may be more productive than relying on posted opportunities under this code classification.
