【Q&A Question 211】August 5, 2018: Briefly explain why, when checking the airtightness of a hydrogen system, it is not sufficient to rely solely on the fact that the pressure drop is within acceptable limits There are many reasons for pressure drop; it may be caused by leaks in multiple seals, or it may be due to severe leaks at a few seal points. If it is the former case, it meets the requirements, but the latter situation is absolutely unacceptable in hydrogen-handling systems, as otherwise, a large amount of hydrogen leakage in those few areas after operation could lead to an explosion. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

There are many reasons for pressure drop; it may be caused by leaks in multiple seals, or it could be due to severe leaks at a few seal points. If a few of the sealing points leak, problems will arise once the machine is started up, and this could lead to combustion or explosion.

There are many reasons for pressure drop; it may be caused by leaks in multiple seals, or it may be due to leaks in just a few seal points. If the former is the cause, it is acceptable, but the latter situation is absolutely not permitted in hydrogen systems, as otherwise a large amount of hydrogen could accumulate in those areas during operation, posing a risk of explosion.
