Several sealing types for internal floating roof storage tanks

Currently, **some of the official documents issued specify that there are three types of sealing methods for internal floating roof storage tanks: mechanical shoe type, liquid interlocking type, and gas interlocking type. However, ordinary enterprises use the pouch-type sealing format. It is certain that capsule seals do not belong to the mechanical type. So, does this commonly used capsule seal fall under the category of liquid embedding or gas embedding? I’ve seen some discussions online suggesting that the term \"liquid and gas inlaid\" is a translation from American standards, but no one knows exactly what it entails. What are the differences between this commonly used sacular seal in China and their liquid-infiltration and gas-infiltration types?
You can take a look at this post – it discusses the sealing method between the floating roof and the tank wall in internal floating roof storage tanks. What do the actual drawings or photos of this design look like? https://bbs.hcbbs.com/thread-1679249-1-1.html (Source: Huahai Chuanliu – Haichuan Chemical Industry Forum Website)
By cystic seal, I understand it to correspond to the elastic filling-type seals used in China; there have been discussions on this topic in the forum: https://bbs.hcbbs.com/thread-1679249-1-1.html
It can be understood that sacular-solid sealing does not belong to the liquid-inclusion type or gas-inclusion type, right? What’s the difference among the three?
I just want to know whether the sacular seal belongs to the gaseous inlay type or the liquid inlay type; if not, what are the differences among the three?
