ISOLATION GASKET, SYSTEM AND METHOD OF MANUFACTURE |
摘要 |
<p>Sealing systems for high pressure applications that provide electrical isolation between joined elements as well as enhanced resistance to leakage of media during a fire. High pressure sealing is accomplished using a metallic core to which an electrically isolating material is bonded on either or both sides. Sealing is achieved through a dielectric sealing element, such as a spring-loaded polytetrafluoroethylene (PTFE) ring. Flanges of the joint may be bolted together with the seal interposed therebetween, and the flanges bolted together. In the event of a fire, heat may be generated that is at a high enough temperature to burn away the isolating material and PTFE ring. Systems of various embodiments provide a metal core backup seal and a compression limiter, which, respectively, prevent the media from leaking from the joint and maintain bolt load at the flanges.</p> |
