About the choice of sealing structure

This post was last edited by May 1st Labor Day on 2010-2-1 11:46. Now I have a heat exchanger to quote, with a diameter of 500mm, a design pressure of the pipe box of 25MPa, a temperature of more than 300 degrees, and two pipe passes. What kind of sealing structure should the pipe box flange use? Can you give me some advice if you have ever done such a high pressure heat exchanger? Thank you! ! !
The pipe bundle is generally a U-shaped bundle. The sealing adopts forced sealing. A 10mm stainless steel round blind plate can be used with the surfacing stainless steel sealing surface of the pipe box flange (which needs to be processed after surfacing). The flange cover is connected to the pipe box flange by bolts. The stainless steel round blind plate of this structure plays a forced sealing role, and the flange cover plays a pressure-bearing role. The advantage is that the sealing is reliable, but the disadvantage is that maintenance is not very convenient.
I don’t understand the structure mentioned above. Can you post a picture so that we can learn from it?* one time. Everyone will rate you
