Style 2000IC
Flexible Graphite, Wire Reinforced
Description and Applications
Style 2000IC is manufactured from high purity flexible graphite that is expanded and formed into a weave-able yarn and then braided in a unique construction with wire reinforcement. The finished product retains all the inherent benefits of flexible graphite; while the wire reinforcement provides greater mechanical strength. Style 2000IC packing is particularly suited for use in high temperature, high pressure steam service. In addition, it can also handle most chemicals, acids and alkalis. This style is excellent for use in steam turbines, high temperature motor-actuated valves and for high pressure/high temperature valve applications in general.

Fugitive Emission Test
Objective
To qualify packing style 2000IC for fugitive emissions in valves when subjected to thermal and mechanical cycles.
Leak detection method
“EPA method 21”.
Test Procedure
ARCO Fugitive Emission Test Specification.
Test Parameters
3 thermal cycles at room temperature and at 177ºC;
Leakage measurements are performed before and after each thermal cycle and at each 100 cycles of the shaft;
Test pressure: 645 psig (45 Kgf/cm2);
Test Fluid: Foxboro OVA128 (99% methane);
Maximum allowable leakage: 100 PPMv (if the leak allowed exceeds 100 PPMv, the sobreposta must be adjusted).
Conclusion
Packing 2000IC has successfully completed the test with 5 adjustments during the 3,500 cycles while maintaining leakage under 100 PPMv.
