DIPERMET determines the t0-value of steel plates to be enamelled. The t0-value is the time required for the diffusion of hydrogen, generated on one side of a steel plate, to the other side of the plate. The t0-value is in direct relation to the effective diffusion coefficient (Deff) of the atomic hydrogen solved in the steel sheet. The t0-values determined for plates of various thicknesses will be normalized to a conventional plate thickness of one mm in proportion to the quadrates of the individual plate thicknesses. The t0-limit value to be used as qualification basis will be recorded experimentally.
Advantages of DIPERMET
- Parallel measurements made by two sensors guarantee the reliability of the measuring results
- No need to fill the closed space on the other side of the plate with water
- Possibility of a second measurement on the surface of the plate, providing further information to judge the sensitivity to scaling
- The entire process of emission of hydrogen is recorded
- Use of various evaluation procedures as per the DIPERMET software supplied
