How to reduce vibration in throttling expansion

2008-01-23View Original

Thread Content

 In our workshop, when diluting liquid ammonia, severe vibrations occur along with loud noises. The liquid ammonia being diluted is at -10 degrees Celsius and under a pressure of 10 kilograms; the pipes used for this dilution are D32 stainless steel straight pipes. It is possible that the vibration is caused by throttling expansion, or it could be due to the heat released during the dissolution of the liquid ammonia. The exact cause is not clear, so I would appreciate any advice from everyone – please help me find a solution!
