UNSPSC 40174402: Forged steel pipe spectacle blind flange

Pipe spectacle blind flange made of forged steel

UNSPSC 40174402 Forged steel pipe spectacle blind flange is a Commodity code that represents a niche component used in pressurized pipeline systems, typically employed in water and wastewater infrastructure applications where isolation, inspection, or maintenance of pipeline segments is required. State and local governments procure spectacle blind flanges — metal plates with dual faces (one open, one solid) that can be rotated between open and closed positions — as part of capital projects involving water treatment facilities, sanitary sewer systems, stormwater management, and industrial utility infrastructure. The issuing bodies soliciting under this code include county sanitation districts, county public works departments, and municipal water and wastewater utilities across the water infrastructure sector.

Recent state and local activity under this code centers in California, specifically within Santa Clara County's water and wastewater infrastructure programs. County Sanitation District No. 2-3 posted an ITB (ITBRDAFY270088) on August 26, 2026, due September 17, 2026, for the Structural Defect Repair Project Phase 2, a sewer infrastructure rehabilitation program in the unincorporated eastern foothills involving sanitary sewer mainline point repairs, pipe-burst replacements, and mainline extensions; while the primary scope emphasizes PVC and HDPE pipe replacement rather than spectacle blind flanges explicitly, such components typically appear as accessories in sanitary sewer system isolation and maintenance work. Santa Clara County also posted an ITB (ITBRDAFY260694) on April 29, 2026, due May 21, 2026, for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, a pavement and utility infrastructure project that may include subsurface utility modifications where isolation components are specified. The code shows limited recent posting activity; procurement under 40174402 is episodic and concentrated in specialized water and wastewater capital projects rather than routine or high-frequency acquisitions.
