Precision Casting Process: Made via investment casting, with dimensional tolerance controlled within ±0.1mm and surface roughness Ra≤3.2μm. It can be directly assembled without secondary machining after forming. Strong Material Compatibility: Supports various materials such as carbon steel and stainless steel. After professional heat treatment, it has excellent wear resistance, impact resistance, and corrosion resistance, adapting to the harsh working conditions of railway locomotive air systems and brake pipelines. Structural Advantages: The one-piece molded concentric reducer design ensures smooth fluid transition, reduces eddy currents and resistance, and improves the operational stability of the pipeline system. Quality Assurance: Equipped with non-destructive testing and three-coordinate inspection throughout the whole process, the defect rate is less than 0.3%. It meets railway industry standards and is suitable for various rolling stock such as high-speed railways and conventional railways. 【Application Scenarios】 Air system connection of railway locomotive braking systems, pipeline reducer adaptation of rolling stock, fluid pipeline transition of urban rail transit, etc.
