1. VDI 2200 - leakage test & safety against blow-out – for flange connections

• at temperature range from RT to 550°C
• at pressure range 1bar
• additionally at pressure 40bars (as addition to standard requirements)

2. VDI 2440 - leakage test TA-Luft for valves

• at temperature range from RT to 550°C
• at pressures range from 0 to 160bars
• possibility of Live Loading apply during testing
   

Sample test run:

• Assembly of the valve in the test rig
• Preliminary test at RT: short term leakage test
• Heating up to max. 400 °C
• Stem cycles at test temperature (1,000 pcs.)
• Tightness test 24 hours, test medium Helium, test pressure max 160 bar,
• Disassembly after test
• Evaluation of test results

3. VDI 2200 - blow-out test

• test temperature acc. specification of manufacturer for the seal in mounted state
• installation surface pressure as per Qmin/0,01 (EN 13555)
