Expanded Graphite Die-formed Ring

Expanded Graphite Die-formed Ring Choose suitableexpanded graphite material,such as industrial grade, low sulphur grade,Oxidation & corrosion resistant or nuclear grade.Press molded into a ring form of requiredsize and shape. According to the working conditions,it can reinforced withsteel tape or wire mesh on the middle, top and bottom of ring, it can be usedto sealhot water, high temperature andpressure steam,heat transfer fluid, ammonia,hydrogengas,organic solvents,hydrocarbons,cryogenic liquids(LN, LHe, LNG, LPG etc.) etc.PS-790 (Expanded Graphite Die-Formed Ring) PS-791(Expanded Graphite self-sealing Ring)   PS-792 (Expanded Graphite self-sealing Ring) PS-790(R) Expanded Graphite ring reinforced by metal strip or wire mesh) PS-791(R)Expanded Graphite self-sealing Ring reinforced by metal strip or wire mesh) PS-792 (R) Expanded Graphite self-sealing Ring reinforced by metal strip or wire mesh)PS-790(C) Expanded Graphite Ring reinforced by metal cover on top and bottom)PS-790(B) (Expanded Graphite Ring reinforced by metal cover on ID & OD) PS-791(C) (Expanded Graphite self-sealing Ring reinforced by metal cover on top and bottom)PS-792(C) PS-791(B) Expanded Graphite self-sealing Ring reinforced by metal cover on top and bottom)PS-790(M) (Expanded Graphite Ring reinforced by wire mesh on top and bottom) PS-798(R)(Expanded Graphite gasket and SS316 flat formed ring) PS-798(T)Expanded Graphite gasket and SS316 tanged insert formed ring) PS-796Expanded Graphite ring with SS304 oval or round eyelet)PS-780 (No Leakage Combined Packing Ring) No leakage combinedPackingring This packinguse Carbon Fiber Packing ring on both top and bottom, Second ring on top and bottomwith high density of graphiteself-sealingringwith 30, middle filledwith low density of graphite ring with 45PS-799 (Combined Packing Ring w/high pressure) This packing use each yarn wire mesh jacketed graphite packing ring on the top and bottom, middle filledwith pure graphite rings.   Density   Carbon Content   Sulphur Content   Chlorine Content   Temperature   Ignition LossPressure   Compressibility   Recovery1.2~2.0 g/cm398~99.8% 200~1200PPM 30~50PPM 240~560℃ 0.2~0.8% 20~50MPA 10~25% ≥35%
