What are the media with high permeability? Besides kerosene, there are also,,,,
Reply to 2# yiransunny: High-pressure hydrogen too? That thing is dangerous, right?
Reply to 1# gw821022: Gases such as hydrogen, helium, ammonia, halogen gases, low-molecular-weight alkanes and olefins (or liquefied gases), as well as light petrochemical products like gasoline, methanol, and benzene.
What are the requirements for permeable media in terms of material selection?
What are you going to do, conduct tests or something else?
Paragraph 2 of Article 3.17 of the \"Regulations on Safety Technical Inspection of Fixed Pressure Vessels\" stipulates that pressure vessels handling highly permeable, moderately hazardous media shall use high-neck butt-welded flanges at least; such highly permeable, moderately hazardous media mainly refer to gases (or liquefied gases) such as hydrogen, helium, ammonia, halogen gases, and low-molecular-weight alkanes and olefins, as well as light petrochemical products such as gasoline, methanol, and benzene.
Besides the answers to questions regarding tolerance specifications on highly permeable media, are there any standards or books that specify which media are considered highly permeable?
Are there any available data on the strength of permeability?
