Hydrogen and ammonia leakage test methods
Thread Content
I would like to ask fellow sailors: since there is hydrogen and ammonia inside the tower, which leakage testing method is the best to use?
Portable combustible gas detectors, hydrogen detectors, ammonia detectors (self-priming with long tube for insertion), balloon sampling gas chromatography.
Can’t use a tightness test for the leak test?
First, use a gas detector for qualitative analysis to determine whether there is a leak. Then conduct a airtightness test using soapy water to identify where the leak is
If you can only choose between these two gases, it’s better to use ammonia for leak detection, as there are standards to rely on. The hydrogen leak detection method is a technique that uses a mixture of 5% hydrogen and 95% nitrogen as a tracer gas for leak detection. The advantages are: low cost, and the ability to achieve sensitivity similar to that of helium leak detection. The disadvantage is: the lack of relevant standards, and uncertain leak detection parameters.
Thank you so much to all the sea friends for their answers and help! Looking for a basis for nitrogen leak detection
Use a hydrogen detector or check for leaks with the lights off at night
Was the leakage fixed using nitrogen in the end? ?
