When sealing, ceramic fiber paper must ensure the sealing effect, that is, its sealing must meet certain conditions. Whether in a good environment or a bad environment, it must ensure long-term and useful sealing. If such requirements are met, it generally has the following important characteristics. Let’s look at it together:


1. Air tightness: as for the medium of the sealing system, the gasket shall ensure that there is no leakage within a certain period of time during temperature and pressure operation.
2. Compressibility: the contact surface between gasket and flange shall be in good conformity after the connecting bolt is fastened to ensure sealing.
3. Creep resistance: under the influence of pressure load and service temperature, the creep resistance shall be good, otherwise the bolt torque will be lost, resulting in the reduction of the external stress of the refractory fiber paper gasket, and then the leakage of the system.
4. Chemical corrosion resistance: the selected refractory fiber paper shall not be corroded by chemical medium and shall not corrode the medium.
5. Resilience: even when the system is stable, the two flanges connected will certainly have small displacement due to the influence of temperature and pressure, and the elastic function of the gasket shall be able to compensate this displacement to ensure the tightness of the system.
