    • Commodity name: Air knife air duct

    1. Material: 6061 aluminum alloy

    2. Manufacturing process: material cutting, continuous welding, stress relief, CNC machining, removal of internal weld slag, ensuring unobstructed pipelines free of residual impurities.

    3. Dimensional Features: A long, integrated multi‑path piping structure with a large‑angle elbow at the end of the straight main section; multiple sets of vertically oriented branch pipes evenly distributed along the pipe body; square mounting flanges at both ends, with pre‑drilled mounting holes for secure installation; standardized interface dimensions for branching connections and high dimensional consistency across production batches, facilitating interchangeable assembly in equipment.

    4. Surface Treatment: Natural-color anodizing, hard-anodizing process

    5. Product Applications: Primarily used in cooling water circuit assemblies for automation equipment, hydraulic distribution pipelines, multi-channel delivery lines for vacuum systems, and heat‑dissipation manifolds for new‑energy devices. The integrated multi‑port design enables a single fluid stream to be split into multiple branches, while the flanged connection facilitates quick installation and secure mounting of the entire unit. It is widely employed in custom‑designed equipment, new‑energy systems, and fluid‑cooling systems.
