UNSPSC 40175000: Pipe weldneck flanges

UNSPSC 40175000 Pipe weldneck flanges is a Class code whose name misaligns with the actual scope of work state and local governments are purchasing under it. Recent solicitations tagged to this code do not involve weldneck flanges but rather comprehensive sewer and pavement infrastructure projects requiring pipe materials, fittings, and related components as inputs to larger rehabilitation programs. Santa Clara County has posted two recent ITBs—the County Sanitation District No. 2-3 Structural Defect Repair Project Phase 2 (due September 17, 2026) and the Central Expressway Pavement Rehabilitation Project Between Bowers Avenue and Scott Boulevard (due May 21, 2026)—both awarded as invitation-for-bid notices requiring sealed physical submissions to the County Clerk. The sanitation project involves removal and replacement of vitrified clay pipe with PVC and HDPE pipe at multiple diameters, service connection wyes, and precast concrete manholes across thirty-five point repairs and two mainline extensions. The pavement project encompasses partial depth recycling, asphalt overlay, concrete curb and gutter work, ADA improvements, and traffic infrastructure modifications. The issuing body across both recent opportunities is Santa Clara County.

Activity under this code is limited to California, specifically Santa Clara County, based on the two recent opportunities in the dataset. The sanitation project requires sixty-five working days for completion, while the pavement rehabilitation project allows 142 working days from the Notice to Award. Both solicitations require bids to be hand-delivered to the County Government Center in San Jose; electronic submissions are not accepted. The code shows minimal recent activity and appears to be used inconsistently by the jurisdiction—the nominal scope (weldneck flanges) does not match the actual materials and services being procured. Business development professionals should verify whether Santa Clara County continues to tag infrastructure projects to this code or whether the tagging reflects a data classification anomaly.
