Permeability Test Method of the Material for Graphite Pressure Vessel

Abstract:

In 2009, ASME incorporated the construction specifications of graphite pressure vessels (GPV) in BPV construction codes (BPV VIII-1 part UIG). It is the first time that the non-metallic pressure vessel was incorporated. For the raw materials of GPV, a special property was specified in the codes, i.e. the permeability. As the porous microstructure of impregnated graphite, the permeability becomes a key property for the construction of the GPV especially in the high toxicity applications. In this paper, the whole test technique about the permeability of graphite was discussed, including the computational derivations, design of the test equipment, the test procedure and the result data processing.
