UNSPSC 40174709: CPVC plastic pipe threaded flange

Pipe threaded flange made of CPVC plastic

UNSPSC 40174709 CPVC plastic pipe threaded flange, a Commodity code, covers plastic pipe fittings and components used in water and wastewater infrastructure projects, though recent state and local solicitations tagged to this code predominantly feature PVC and HDPE pipe materials rather than CPVC-specific products. Santa Clara County and its subordinate sanitation districts are the primary active buyers in the recent record, issuing invitations to bid (ITB) for sewer rehabilitation and pavement projects that incorporate plastic pipe replacement and installation as part of broader infrastructure work. The actual purchasing pattern shows demand for PVC SDR26 pipe in multiple diameters (4-inch through 10-inch), service connection fittings such as wyes, and HDPE pipe for trenchless pipe-bursting applications. Issuing bodies include county sanitation districts and county transportation departments, both engaged in long-cycle infrastructure rehabilitation with 65- to 142-working-day completion windows.

Recent activity concentrates in California, specifically the San Francisco Bay Area. The Santa Clara County Sanitation District No. 2-3 issued ITB ITBRDAFY270088 for the Structural Defect Repair Project Phase 2, with bids due September 17, 2026, encompassing 326 linear feet of 6-inch PVC SDR26 pipe, 114 linear feet of 8-inch PVC SDR26, 43 linear feet of 10-inch PVC SDR26, 1,080 linear feet of 6-inch HDPE for pipe bursting, and service fittings including twenty-seven 4"×6" wyes and related components. The same county issued ITB ITBRDAFY260694 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, due May 21, 2026, which included removal and replacement of inductive traffic loops and related drainage infrastructure. The code shows limited recent activity beyond these Santa Clara County opportunities and does not surface standout repeat buyers or geographic spread across multiple states in the available record.
