UNSPSC 40174006: Stainless steel pipe slipon flange

Pipe slipon flange made of stainless steel

UNSPSC 40174006 Stainless steel pipe slip-on flange is a Commodity code that captures stainless steel flanged pipe fittings used in water and wastewater infrastructure rehabilitation and construction. State and local governments procure these components as materials inputs to larger sewer and water main replacement, repair, and extension projects. Recent opportunities show the code supporting sanitary sewer mainline work including pipe replacement, point repairs, pipe bursting, and service connection installations across multiple pipe diameters and configurations. Issuing bodies under this code include county water districts and county public works departments executing infrastructure rehabilitation programs in unincorporated areas and along major transportation corridors.

Santa Clara County is the primary recent buyer, appearing in two separate sewer and pavement rehabilitation solicitations posted between April and August 2026. The County Sanitation District No. 2-3 Structural Defect Repair Project Phase 2, posted August 26, 2026 with an IFB response due September 17, 2026, represents direct procurement of pipe fittings and related components for a thirty-five-point repair and five pipe-burst replacement program in the unincorporated eastern foothills; the scope explicitly names service connection wyes (4"×6", 4"×8", and 4"×10" configurations) alongside PVC and HDPE pipe replacement. Santa Clara County's Central Expressway Pavement Rehabilitation Project Between Bowers Avenue and Scott Boulevard, posted April 29, 2026 with an IFB due May 21, 2026, represents a broader pavement and infrastructure rehabilitation effort requiring 142 working days to completion. Geographic activity concentrates in California, specifically the Santa Clara County jurisdiction. Bidders must submit proposals in physical form to the County Clerk of the Board of Supervisors; no set-asides or preferential procurement designations are identified in the recent postings.
