Mechanism and Countermeasures of Sheet Gasket-Specific "Penetration Leakage" [Technical Explanation]
An explanation of the often-overlooked mechanism of "permeation leakage" and why thick gaskets can lead to leaks, along with the physical reasons behind it!
Have you ever been troubled by such inexplicable minor leaks at the piping site? It may not be "interface leakage" that leaks from the gap between the gasket and the flange, but rather "permeation leakage," which leaks through the material of the gasket itself. In particular, when using "sheet gaskets" such as joint sheets, the risk of this permeation leakage is always present. The most effective countermeasure for this is to "make the gasket thinner." In this article, we will explain the often-overlooked mechanism of "permeation leakage" and the physical reasons why thick gaskets can lead to leaks. *For more detailed information, you can view the related links.
