Cold hydrogenation pressure holding

It depends on the temperature and other electrical requirements; if the holding time is too long, it becomes pointless
Could you please describe it in simple detail? Thank you
Reply to 3# zhouhongchang: The pressure retention requirements for the cryohydrogenation system are the same as those for pressure testing and pressure retention in ordinary chemical pipelines and equipment systems. There are corresponding standards available for reference.
General standards for chemical pipelines and equipment can be referred to; no special requirements apply
