The magnetite is formed by controlling the water chemistry and the temperature of fluid inside the facility. 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 layer of magnetite on e180 surface of A is thicker than that of A P22, due to the different amount of chrome content.

However, after a certain period of time, the mass loss rate of A P22 became greater than that of A B. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

ASTM E – 08() Standard Practice for Preparing Sulfur Prints for Macrostructural Evaluation

For specific precautionary statements, see Section 9. In nuclear power plants, carbon steel piping having experienced wall thinning degradation is generally replaced with low-alloy steel piping. 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.

The sulfur print complements macroetch methods by providing an additional procedure for evaluating the homogeneity of a steel product. 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.

Standard Practice for Preparing Sulfur Prints for Macrostructural Examination

Under carefully controlled conditions, it is possible to compare print image intensities if the images are formed only by manganese sulfides.

It is presumed that the results are caused by the different yield strengths of the test materials and the different degrees of buffer action of the magnetite deposited on their surfaces.

No other units of measurement are included in this standard. The density of the print image should not be used to assess the sulfur content of a steel. However, the materials of pipes carrying two-phase flow should be selected considering their susceptibility to LDIE. 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.

ASTM E1180 – 08(2014)

Scientific Research An Academic Publisher. Steels with compositions that produce predominantly titanium or chromium sulfides will not produce useful images. It has been thought that wall thinning on the secondary side piping in nu-clear power plants is mostly caused by Flow-Accelerated Corrosion FAC.

In the initial stage of the experiments, the mass loss rate of A E1108 was greater than that of A P Very low sulfur content steels will produce sstm faint an image to be useful for macrostructural evaluations.

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

Historical Version s – view previous versions of standard. An experimental facility was set up to develop a prediction model for clarifying multiple degradation mechanisms that occur together. Selection of appropriate printing practices including selection of type of emulsion coated media, acid type and strength, will yield satisfactory prints.
