For integrated inspection and performance verification of oil tank breathing valves, hydraulic relief valves, and flame arresters in accordance with CNPC standards.
The ODMT Oil Tank Accessories Inspection Equipment is an integrated test bench designed for the inspection and verification of oil tank accessories.
It is developed and manufactured in accordance with China National Petroleum Corporation Standard Q/SY 080072017, and is suitable for standardized testing of key oil tank components.
The Oil Tank Accessories Integrated Test Table is used to test the performance parameters of oil tank accessories such as breathing valves, hydraulic relief valves, and flame arresters.
The equipment supports inspection of ventilation capacity, opening pressure, and pressure loss, ensuring that oil tank accessories meet specified industry standards and safety requirements.
| Norms (DN, mm) | 50 | 80 | 100 | 150 | 200 | 250 | 300 |
| Ventilation Capacity (m³/h) | 150 | 300 | 500 | 1000 | 1800 | 2800 | 4000 |
Remark:
Rated ventilation capacity refers to outlet ventilation.
Rated outlet ventilation = 1/2 of rated inlet ventilation.
