INSTRUCTIONS FOR LEAKAGE TESTING Before work begins Check -

that the pressure pressure gauge and other test equipment has been calibrated and will withstand the pressure that is to be tested that the connected equipment will withstand the pressure that is to be tested that any possible energy reservoirs such as accumulators, pulsation dampers, etc. have been isolated

-

um When using water as a test medi um that the foundation and supports for the equipment to be tested will withstand the combined weight of the equipment and water used during the test

-

Performance of pressure testing When using water, the equipment shall be filled to 100% first - ensure that the gas is vented at the highest point. 1. 2. 3. 4. 5. 6.

Increase the pressure to approx. 10% of the test pressure – maximum 10 bar. Check for possi possible ble leaks (flanges, plugs, etc.). Increase the pressure gradually gradually to 50% of the test pressure. Check for possible leaks (flanges, plugs, etc.). Increase the pressure gradually to the test pressure. Maintain the pressure for an adequate period of time in order order to perform perform a thorough thorough check for leaks Avoid shock loads Avoid passing in front of possible leakage points ible temperature variations that can influence in fluence the pressure Monitor any poss possible

After pressure testing 1.

Reduce the pressure gradually to atmospheric pressure

2.

In the event of drainage : -

refill nitrogen at the highest point – avoid creating a vacuum

-

check that the drainage system is not overloaded ov erloaded

3. Check that all all parts of the tested system have have been depressurised/draine depressurised/drained d – low points, check valves, etc
