Gasket hermetics
Sealing System for the media, gasket in the recommended temperature and pressure of work in a certain period of time does not leak.

Gasket compressibility
Gaskets and flange connections in the access of the fastening bolts, it should be good anastomosis to ensure that the seal

Creep resistance of the gasket
Gasket in the use of temperature and pressure loads under the influence of anti-creep should be better, or to cause loss Niuju bolts, resulting in decreased stress gasket surface, thereby leaking gas system hardware.

Gasket chemical corrosion resistance
Gaskets should be selected from the chemical corrosion media, and not contaminated medium.

Gasket resilience
Even in a situation of stability system, connecting the two flange as a result of temperature and pressure affect sure there will be minimal displacement, the flexibility pads should be able to compensate for this shift, in order to ensure the sealing system.

Anti-bonding pads of
In the use of pads should be readily removed from the flange, not bonding

Non-corrosive gasket
Connecting flange gasket surface should not corrosive.

Resistance temperature gasket
Gaskets should be chosen to ensure that the minimum temperature and maximum temperature under normal use.
