160L High Volume Welded Main Air Reservoir Railroad Air Receiver for Brake System
160L High Volume Welded Main Air Reservoir Railroad Air Receiver
Product Overview
The 160L welded main air reservoir is a high volume air receiver purpose-built for railroad pneumatic braking systems. As a core pressure vessel, it stores compressed air for locomotives, freight wagons, passenger coaches and railway engineering vehicles to ensure stable brake operation.
Compared with small-capacity auxiliary tanks, this high volume air receiver delivers steady, sufficient air supply and minimizes system pressure fluctuations. The all-welded structure provides superior air tightness and structural stability. Our railroad air reservoir adapts to harsh working conditions and complies with mainstream international railway pressure vessel standards.
Core Features
- Large Volume Air Storage: 160L high-capacity design sustains stable air pressure for heavy-load and long-marshalling railway vehicles, eliminating frequent pressure drops.
- Reliable Welded Structure: Full welded construction with NDT inspection ensures zero air leakage and strong vibration resistance for long-term railway service.
- Railway-Grade Durability: Made of premium vessel steel or stainless steel with anti-corrosion treatment, suitable for dusty, humid and low-temperature railway environments.
- Standard Pressure Performance: Strictly tested per railway standards, with stable pressure resistance and qualified hydrostatic & air tightness performance.
- Flexible Customization: Compatible with global mainstream brake systems (Knorr, Wabtec). Custom size, ports and mounting structures are available.
- Wide Temperature Adaptation: Reliable operation from -50°C to +70°C, covering cold, hot and high-altitude railway scenarios.
