UNSPSC 40173100: Pipe lapjoint flanges

UNSPSC 40173100 Pipe lapjoint flanges is a Class code that covers pipe flanges and related fittings used in gravity-fed wastewater and stormwater infrastructure. State and local governments procurement under this code centers on sewers, drainage systems, and related gravity pipeline networks where flanged connections are required for assembly, repair, or replacement. The issuing bodies include county sanitation districts and county public works departments executing infrastructure rehabilitation and capital improvement projects. Pipe lapjoint flanges are typically specified as components within larger sewer mainline repair, replacement, and extension work, where they facilitate connections between sections of pipe or allow for future access and maintenance.

Recent activity concentrates in California, where Santa Clara County has posted multiple infrastructure rehabilitation solicitations. The County Sanitation District No. 2–3 Structural Defect Repair Project Phase 2, solicited as IFB ITBRDAFY270088 with a response deadline of September 17, 2026, encompasses sanitary sewer mainline point repairs and pipe-burst replacements across eastern foothills in unincorporated Santa Clara County, including removal and replacement of vitrified clay pipe, high-density polyethylene pipe bursting, and service connection fittings such as 4-inch × 6-inch, 4-inch × 8-inch, and 4-inch × 10-inch wyes. The Central Expressway Pavement Rehabilitation Project Between Bowers Avenue and Scott Boulevard, solicited as IFB ITBRDAFY260694 with a response deadline of May 21, 2026, represents a broader County road and drainage infrastructure project that may include ancillary drainage or utility work where flanged connections are specified. Both solicitations require physical bid delivery to the County Government Center in San Jose and do not accept electronic submissions.
