Application of Octagonal Ring Joint Gasket

The metal octagonal ring gasket is touched by the gasket with the inner and outer surfaces (mainly the outer side surface) of the trapezoidal groove of the flange. The metal ring gasket is a solid metal gasket with an octagonal or elliptical cross-sectional shape processed from metal materials. The octagonal ring gasket, which is compressed to form a seal, matches the flange groove, which mainly indicates that it is surface touch. Compared with the oval ring gasket, although it is not easy to achieve a close fit with the flange groove, it can be used again, and because the cross section is formed by a straight line, it is easy to process. There are actually many different categories of such products. According to different application properties, they can be divided into metal octagonal gaskets, octagonal metal ring gaskets, and metal octagonal gaskets.

The metal octagonal ring gasket has good sealing performance, but the processing accuracy is high, so the production cost is increased, and it cannot be reused compared to the oval ring gasket. Corrosion resistance and low hardness metal ring gasket: Use customized low-carbon content metal materials to adjust trace elements and have a radial self-tightening sealing effect. The modification of the general heat treatment method ensures the realization of the low-hardness metal ring gasket. The products are widely used in the static sealing parts of high temperature and high pressure equipment and technical pipelines in many occupations such as petrochemical industry, chemical industry, metallurgy, refining, gas, nuclear energy, thermal power and so on
