Static temperature and pressure load

The flow rate of the device under test can reach the temperature required to ensure a constant temperature. Before starting the test, the maximum flow rate of each device under test must be agreed with the corresponding department, and the example must be recorded.

Corrosion in the device under test caused by flow is not allowed

Number of devices under test: 4 new parts

Temperature: 107℃-110℃

System pressure: 1.5 bar overpressure, control of test media throughout the duration of the test, 60% coolant additive mixture TL774 and 40% water test duration 1500h

Program heating cycle

1. Heat the heating unit to 110 ° C

2. After 170 hours, cool it to room temperature

3. Store at room temperature for 1 hour, replace the existing test medium with a new test medium

4. Heat to 110 ° C

5. Check the sealing
