Is the pocket float seal (packing seal) a high-efficiency seal? Meets GB20950 requirements?

It must be ensured that high-efficiency sealing methods such as liquid-immersed seals or mechanical shoe seals are used between the floating disk of an internal floating roof tank and its tank wall.

\"High-efficiency sealing\" is just a term; such a form of sealing actually does not exist. To ensure a good sealing effect, a dual-sealing system using a bladder and a tongue plate can be considered

Same question: Does the pouch-type seal meet the requirements for high-efficiency sealing as specified in GB20950?
