Disadvantages of the biconical seal structure
Thread Content
I am currently working on a high-pressure device that uses a biconical seal structure. The books mention its advantages, but I would like to know what the disadvantages are
It is not effective for ultra-high pressure vessels
The bolt force is high; especially under high pressure, a larger bolt cross-sectional area is required, which inevitably leads to larger flange dimensions and is not economical! Furthermore, the sealing surface is relatively wide, making it unsuitable for ultra-high pressure conditions. Overall, double-cone seals are the most widely used in high-pressure vessels, as they have many advantages.
