Application range of mechanical seal gasket sealing technology:

Gasket sealing technology is developed with the development of pressure vessel technology. Although the theory of mechanical seal gaskets for pressure screens is still being explored and developed, the scope of its practical application is getting wider and wider. With the rise of modern industry, especially the modern petrochemical industry, chemical industry, atomic energy industry, and large-scale power stations, pressure vessels are developing toward high temperature, high pressure, high vacuum, cryogenic, large-scale, and single-series, and new ideas for gasket sealing are constantly being proposed. Requirements, a variety of new structures and new materials continue to appear, solving many long-standing problems. Petroleum and petrochemical system equipment, valves, pipe fittings, etc. are used for large-scale detachable flange sealing connections. There are many related standard flange gasket settings and selections of the same internal and external standards, such as domestic GB9112-9125 series, JB4700-4707 series , HG20592-20635 series, SH3406 series; foreign series, API series, ASME/ANSI16.5 and 16.7 series, JIS series, BS series, etc.

However, with the increasing attention to energy and environmental issues, the size, pressure and temperature of equipment have developed to high parameters, replacing the requirements of asbestos chrome sheet materials, and the urgent requirements for overall optimization of flange design. The original design The method and the corresponding seal standard can no longer guarantee the reliability of the seal and the industrial requirements.　　459.html,
