UNSPSC 40172902: Cast iron pipe expansion joint

Pipe expansion joint made of cast iron

UNSPSC 40172902 Cast iron pipe expansion joint, a Commodity code, describes replacement and repair components for municipal wastewater and water distribution infrastructure, specifically rigid piping systems where cast iron segments require jointing, sealing, or expansion accommodation during mainline repair and replacement work. State and local governments solicit these components as part of sewer and water main rehabilitation projects where existing vitrified clay pipe, cast iron, or other legacy pipe stock is removed and replaced or rehabilitated in place. The buying bodies are primarily county sanitation districts, county public works and water departments, and special-purpose wastewater authorities responsible for aging infrastructure in suburban and rural areas. Work solicited under the code centers on point repairs, pipe bursting operations, mainline extensions, and full-section replacements where expansion joints and associated fittings provide structural integrity and accommodate system pressure and thermal cycling.

Recent opportunities show activity concentrated in California and Georgia. Santa Clara County's Sanitation District No. 2-3 posted an IFB (ITBRDAFY270088) on August 26, 2026 due September 17, 2026 for the Structural Defect Repair Project Phase 2, covering thirty-five sanitary sewer mainline point repairs, five pipe-burst replacements at seventeen locations, and two mainline extensions across the unincorporated eastern foothills; the scope specifies removal and replacement of 326 linear feet of 6-inch vitrified clay pipe with polyvinyl chloride SDR26, pipe bursting of existing 6-inch VCP and cast iron with high-density polyethylene, and twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes, with sixty-five working days to completion. The County of DeKalb, Georgia solicited sealed bids for quick insertion valves under ITB 2026-034-ITB (PE64400NONST2027000000268), posted July 27, 2026 due August 27, 2026, as a three-year multiyear contract covering high-pressure and low-pressure quick insert valves, tapping sleeves, resilient wedge insert gate valves, and optional valve insertion equipment for pressurized and non-pressurized pipeline systems. A third Santa Clara County opportunity (ITBRDAFY260694) for the Central Expressway Pavement Rehabilitation Project (posted April 29, 2026, due May 21, 2026) involved broader infrastructure work and does not appear to target cast iron expansion joints directly.
