Test content

1. Pulse pressure cycling test

-Repeatedly increase, maintain, and release pressure according to the set pressure waveform

-Detect whether the inner liner leaks, ruptures, deforms, welds crack, or interfaces leak under alternating pressure

2. Pressure resistance test

-Static holding pressure: rated pressure × 1.5-3 times, holding pressure for 5-30 minutes, no leakage, no permanent deformation

-Blasting pressure: gradually increase the pressure until rupture, record the blasting pressure value and rupture location

3. Sealing test

-Testing under pressure: Check for leaks in interfaces, welds, flanges, and joints

-Commonly used: pressure drop method

4. Temperature coupling test

-High temperature water pulse (40-90 ℃)+pressure cycle

-Simulate the fatigue life under alternating cold and hot conditions in actual use

5. Test of lifespan and durability frequency

-Set cycle times: 10000 to 500000 times

-Inspection after reaching the number of times: appearance, size, sealing, pressure retention ability

6. Pressure waveform and parameter recording

-Real time collection: pressure value, boost time, hold time, release time, number of cycles, temperature

-Automatically generate pressure time curve
