Graphite Gaskets Of The Loose Structure

The metal-free, pure graphite gasket consists of expanded graphite, which is as much as 38 times as much as the raw graphite. The loose structure of the expanded graphite allows the gasket to be molded without any adhesive and to maintain permanent elasticity. A graphite gasket with a high purity and low ash content has proven to be one of a sealed product that can be installed in many different applications with long service life. In addition, Graphite Gaskets compared to other gaskets, pure graphite gaskets show excellent recovery capabilities, and their unique properties, can be used in different branches of different industries. Graphite Gaskets In the construction of nuclear power plants, a large number of nuclear grade gaskets are required. The safety, reliability and economy of the nuclear power plant production system are largely determined by the effectiveness of the seals. The nuclear power plant system equipment has more stringent requirements for the safety and reliability of the sealing components due to the serious and potentially significant accidents involving nuclear leakage.

In addition to high temperature, high pressure, Graphite Gaskets thermal fatigue conditions, the nuclear grade gasket must be equipped with radiation resistance, high reliability, high life and nuclear grade cleaning requirements, subject to compression rate, Graphite Gaskets rebound rate, stress relaxation rate And the maximum leakage rate and a number of technical performance testing and heat exchange test, in order to get permission in the application of nuclear power plants. For the nuclear safety-related system of the gasket, mainly in the flexible graphite composite gasket-based, flexible graphite with its excellent chemical stability, soft resilience, radiation resistance and high temperature resistance, and specially designed composite Type seal structure, successfully meet the requirements of nuclear-grade seal.

Flexible graphite, Graphite Gaskets also known as expanded graphite, was developed in the 1960s as a new type of carbon graphite material, first from the United States in 1968 United carbide Corporation patent. With the petrochemical industry, as well as the rapid development of nuclear power industry, the requirements of the seal is also increasingly harsh. Despite the high price of graphite materials, but by virtue of its series of excellent performance, Graphite Gaskets still ushered in the rapid development, has become a popular new non-asbestos sealing material.
