Ceramic fiber paper with seal, it is important to ensure that the sealing effect can be, that is, its seal must satisfy certain conditions, whether it’s in a good environment, or a bad environment, make sure seal and useful for a long time, and meet the requirements of such words, generally has the following several important features, look at:
1. Air tightness: Regarding the medium of the sealing system, the gasket shall ensure that no leakage will occur within a certain period of time during the temperature and pressure operation.
2. Compressibility: The contact surface between gasket and flange should be in good agreement after the link bolt is fastened to ensure the sealing.
3. Creep resistance: under the influence of pressure load and service temperature, the creep resistance should be good; otherwise, the bolt torque will be lost, resulting in the reduction of external stress of refractory fiber paper gasket, and then causing system leakage.
4, chemical corrosion resistance: the selected refractory fiber paper should not be corroded by chemical medium, and can not corroded medium.
5. Resilience: Even if the system is stable, the two flanges connected must have a small displacement due to the influence of temperature and pressure. The elastic function of the gasket should be able to compensate this displacement to ensure the sealing of the system.
