Flexible Graphite Gaskets
Characteristic for structure
It consists of two flexible graphite rings with nuclear grade and SS316L(or Z2CND17-12) inner and outer ring, there is leak-off holes in the middle of ring.
Medium: water with boron, cooling water, steam, desalted water, oil, air, nitrogen, 30% sodium hydroxide solution, 7% nitric acid solution.
It applies to the nuclear gas system with RCCM 1, 2 and 3 safety techniques, pipeline flanges for instrument and valve body seals, petrochemical oil refining devices with heat recycle, the flanges manhole or hand hole seals for the primary and secondaly side evaporator and voltage stabilizer.
