UNSPSC 40173101: Carbon steel pipe lapjoint flange

Pipe lapjoint flange made of carbon steel

UNSPSC 40173101 Carbon steel pipe lapjoint flange is a Commodity code that names a single component type, yet state and local solicitations tagged under it reflect broader sanitary sewer and water infrastructure rehabilitation work. Based on recent opportunities, the code appears in purchasing when jurisdictions are procuring materials and labor for sewer mainline repairs, pipe replacements, and extensions — work that may include flanged connections as part of larger assembly packages. The issuing bodies are county sanitation districts and county public works departments managing water and wastewater infrastructure in their service territories. The scope encompasses removal and replacement of deteriorated vitrified clay pipe and cast iron with modern polyvinyl chloride and high-density polyethylene alternatives, along with ancillary fittings, service connections, and concrete structures such as manholes and inlets.

Santa Clara County has driven the recent visible activity under this code. County Sanitation District No. 2-3 issued an ITB (ITBRDAFY270088) due September 17, 2026 for the Structural Defect Repair Project Phase 2, soliciting bids for thirty-five sanitary sewer mainline point repairs, five mainline pipe-burst replacements at seventeen locations, and two sewer mainline extensions totaling over 1,500 linear feet of replacement pipe in multiple diameters along with twenty-nine service connection wyes and three new 48-inch precast concrete sanitary sewer manholes in the unincorporated eastern foothills. Santa Clara County also issued an ITB (ITBRDAFY260694) due May 21, 2026 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, which included pavement, drainage, and traffic infrastructure work. Geographic concentration appears limited to California based on these recent records, with Santa Clara County as the dominant issuing body.
