Since graphite seals

Self-sealing from pure graphite flexible graphite paper, the cut after the mold pressed by the spiral wound filler ring. In general, the cross-section of 45 degrees or 30 degrees slope, the pressing process, the general 0.2MM thick stainless steel sheet or stainless steel mesh reinforced. High pressure and temperature conditions of the site, is generally recommended to use the upper and lower surfaces of the metal flake graphite coated self-sealing. With this design, there is a better anti-extrusion capacity. Since graphite seals are generally using the site: high temperature and high pressure steam power plant condenser valve. The main technical parameters: 1, since good wettability 2, rebound coefficient 3, according to user needs, according to 45 ° oblique incision
