500 degrees of high temperature pipeline flange connection, what sealing ring is more appropriate?
Generally use copper or flexible graphite metal gasket. If the pressure requirements are high, it is recommended to refer to the "steel pipe flange" HG/T20615-2009 standard, the flange sealing surface into a convex surface, concave / convex, tenon / groove surface, full plane or ring connection surface. The gasket can be made according to HG/T20627 ~ 20633 and HG/T20635.

But in China there is a civil also has asbestos board, the sealing effect can also. So I think the design should be based on what the design is gasket, what is the gasket?.
