Hydrogen Blister

The 10MoWVNb steel lens gaskets are widely used for the flange linking of high pressure tube in the synthetic ammonia system in chemical fertilizer plant. The gasket worked in H2-N2-NH3 environment at the temperature of 300°C. It often fails because of hydrogen corrosion. The microstructure and corrosion characteristic of the lens gasket were studied by optical microscope. The results showed that the hydrogen blister appeared preferentially at the interface of inclusions. The corrosion depth was 0.65 millimeter. There were little intergranular crack on inner surface.

High-pressure gas containers must be able to withstand high internal pressures because they store compressed gases. Otherwise, cracks or defects may lead to an explosion, which may in turn lead to a large-scale disaster. Therefore, accurate analysis of the causes of cracks or defects and various techniques for detecting cracks or defects are needed. In this research, we analyzed the failure mechanism of a high-pressure gas container through fractography using scanning electron microscopy and optical microscopy and through measurements of their mechanical and chemical properties.
