78L Railway Brake Air Tank Air Receiver Tank for Railway & Industrial Use
78L Railway Brake Air Tank Air Receiver Tank for Railway & Industrial Use
Product Overview
This multifunctional railway air tank, also widely known as brake air tank and air receiver tank, is a high-pressure certified pressure vessel tailored for railway transit equipment and heavy-duty industrial pneumatic systems. Combining professional brake system safety design and industrial air storage & pressure stabilization functions, the 78L tank acts as a core air source buffer and storage device for railway locomotive and freight wagon brake systems, as well as industrial compressed air stations.
It effectively balances compressed air pressure, eliminates airflow pulsation generated by air compressors, stores sufficient air volume for peak demand and emergency braking, and realizes preliminary gas-water separation for clean air supply. Manufactured with premium pressure vessel steel and full penetration welding technology, this air receiver tank features outstanding vibration resistance, low-temperature tolerance and structural stability, fully adapting to extreme outdoor environments and long-term high-frequency cyclic pressure operation of railway and engineering machinery.
Core Product Advantages
- Dual-Purpose Design for Railway & Industry: Perfectly compatible with railway vehicle brake systems and general industrial pneumatic equipment. It ensures safe and sensitive brake response for railway facilities while stabilizing system pressure and reducing compressor operating load for industrial air supply systems.
- Railway-Grade Safety & Durability: Fabricated from Q245R/Q345R pressure vessel steel with integral elliptical head stamping and full penetration welding. All welds undergo strict NDT non-destructive inspection, delivering excellent anti-vibration, anti-corrosion and low-temperature resistance (-40°C to +70°C), suitable for all-weather harsh railway operation scenarios.
- Stable Pressure & Air Purification: Buffers airflow fluctuation and pressure pulsation to avoid frequent start-stop of compressors, improving the service life of pneumatic components. Meanwhile, it realizes preliminary separation of water and oil impurities in compressed air, protecting downstream equipment.
- 100% Strict Factory Testing: Every tank completes standard hydraulic pressure test and full air tightness test, with zero leakage and no structural deformation under rated working pressure. Complete test reports and material qualification certificates are provided for global project inspection.
- Global Standard Customization: Reserved universal mounting ports for air inlet, outlet, drain valve and safety valve. Supports customized G, NPT, BSPP threads, overall dimensions, surface colors and logo printing to meet diverse international assembly and project requirements.
