For specific precautionary statements, see Section 9. The magnetite is formed by controlling the water chemistry and the temperature of fluid inside the facility. Under carefully awtm conditions, it is possible to compare print image intensities if the images are formed only by manganese sulfides. An experimental facility was set up to develop a prediction model for clarifying multiple degradation mechanisms that occur together.

The sulfur print complements macroetch methods by providing aastm additional procedure for evaluating the homogeneity of a steel product. However, the materials of pipes carrying two-phase flow should be selected considering their susceptibility to LDIE. No other units of measurement are included in this standard. It has been thought that wall thinning on e118 secondary side piping in nu-clear power plants is mostly caused by Flow-Accelerated Corrosion FAC.

Selection of appropriate printing practices including selection of type of emulsion coated media, acid type and strength, will yield satisfactory prints.

In the initial stage of the experiments, the mass loss rate of A E1108 was greater than that of A P Link to Active This link will always route to the current Active version of the standard.

Very faint images in the sulfur print can be made more visible by scanning the sulfur print into a PC, and using a photo editor to increase the color saturation. Very low sulfur content steels will produce too faint an image to be useful for macrostructural evaluations. However, after a certain period of time, the mass loss rate of A P22 became greater than that of A B. Steels with compositions that produce predominantly titanium or chromium sulfides will not produce useful images.

ASTM E – 03e1 Standard Practice for Preparing Sulfur Prints for Macrostructural Examination

The layer of magnetite on the surface of A is thicker than that of A P22, due to the different amount of chrome content. This paper presents a comparison of the mass loss rate of the tested materials between carbon steel A B and low alloy steel A P22 resulting from degradation effect.

In nuclear power plants, carbon steel piping having experienced wall thinning degradation is generally replaced with low-alloy steel piping.

Historical Version s – view previous versions of standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The experimental facility allows examining liquid droplet impingement erosion in the same conditions as the secondary side piping in nuclear power plants by generating the magnetite on the surface of the test materials. The density of the print image should not be used to assess the sulfur content of a steel. It is presumed that the results are caused by the different yield strengths of astk test materials and the different degrees of buffer action atm the magnetite deposited on their surfaces.
