UNSPSC 31351200: Welded or brazed tube assemblies

UNSPSC 31351200 Welded or brazed tube assemblies is a Class code covering tubular metal assemblies with welded or brazed joints, as currently solicited by state and local government for repair parts inventory and operational stock. The City of Arlington, Texas issued an annual requirements contract solicitation (IFB 270041, due October 22, 2026) for brass water repair parts including service line fittings, accessories, and tapping saddles for warehouse stock replenishment. The scope reflects a narrow slice of the broader code — governments are buying pre-fabricated brass tube assemblies and related fittings for water system maintenance rather than the full range of welded or brazed tubing that the code nominally encompasses. Issuing bodies under this code include municipal water utilities and other local infrastructure departments procuring replacement components for routine system upkeep and stock rotation.

The available recent opportunity data is limited to a single posting from a Texas municipality. The City of Arlington's brass water repair parts contract represents municipal-level procurement in the South, though the source provides no visibility into activity in other states or regions. Bidders must submit responses electronically through the City of Arlington's designated Euna Procurement channel; paper bids are accepted only if sealed and properly labeled, and late submissions are rejected. The City emphasizes that solicitations received outside Euna Procurement may be incomplete and could render bids non-compliant, making registration and close monitoring of that platform essential for vendors pursuing this opportunity.
