采用一定厚度的金属板车削而成，高强度，低失弹，应用广泛。
可用于炼油、化工、石化工厂和发电、核电站等高温、高压、蒸汽或气体管道，法兰连接和阀盖连接，非常适宜于窄面法兰连接。
These gaskets are used for high temperature and high pressure steam,gas line valve caps and pipe flanges, they have sharp 60o or 90o concentric grooves machined at l mm pitch over the plain metal surface. These sharp points take up the surface contact pressure very well and provide good sealing with a low clamping force. Consequently, they are very effective where a narrow flange width is required and can be usefully employed where heavy tightening is not possible because of the material quality and construction of the flange.
