To control the amount of leakage of the material in the container outward or inward (under vacuum or reduced pressure conditions) within the scope of the process and environment allowed, hamernaker *** * flange connection harmonic element CSG-40-160-2UH to achieve "tight leakage". The mechanism of leakage is complex, and there are many factors causing leakage, including design, manufacturing, installation and use of various aspects, to ensure that the bolt flange connection is tight and does not leak, hamenacker *** flange connection harmonic unit CSG-40-160-2UH must be consistent efforts from the above aspects.

From a design point of view, if the bolted flange connection is considered as a system. And the focus on "leakage" as a design criterion, both theoretically and practically speaking is no doubt sound. It is also an important subject of design research for many years. However, it has not been put into practice so far. The key of the Harmonic element CSG-40-160-2UH of Hamenako *** flange connection is that the gasket performance, which reflects the advantages and limitations of the whole bolted flange connection seal, is extremely complex and lacks sufficient test data and regular mathematical description
