Heat resistance of mechanical seal metal padding:

As the core material of metal cladding, the heat resistance of FBD mechanical seal is the main assessment index. Generally, asbestos board or asbestos rubber board with low rubber content, carbon fiber or porcelain fiber with good high temperature resistance (generally refers to silicon carbide fiber, silicon nitride, boron nitride fiber) and flexible graphite sheet are used.

Metal clad gaskets can be made into various special-shaped gaskets. For example, oval, square, fork-shaped or fork-shaped or more complex shapes can meet the sealing needs of various heat exchanger tube boxes and non-circular pressure vessels, but other composite gaskets cannot.　　476.html,
