Raku-Raku®超高温石墨金属缠绕垫片
Raku-Raku®超高温石墨金属缠绕垫片采用最新研发的超高温石墨材料为石墨带基材，它不但具有普通石墨缠绕垫片的所有特性，而且在氧化状态下最高温度可达到650℃，在持续高温下的稳定性是普通石墨缠绕垫片无法达到的。因此解决了在超高温领域的密封要求。
Raku-Raku®Ultra-high Temp. Graphite Spiral Wound Gasket
The gasket is Using the newly developed ultra-high temperature graphite material as the base material of graphite strip.Not only does it have all the properties of ordinary graphite wound gaskets, but the maximum temperature can reach 650°C in the oxidation state,the stability at constant high temperatures cannot be achieved by ordinary graphite spiral wound gaskets.It solve the sealing requirements in the field of super high temperature.
