ASTM E1180 – 08(2014)
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 asfm from degradation effect.
The magnetite is formed by controlling the water chemistry and the temperature of fluid 1e180 the facility. For specific precautionary statements, see Section 9. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The density of the print image should not be used to assess the sulfur content of a steel. Under carefully controlled conditions, it is possible to compare print image intensities if the images are formed only by manganese sulfides.
Scientific Research An Academic Publisher. Link to Active This link will always route to the current Active version of the standard. An experimental facility was set up to develop a prediction model for clarifying multiple degradation mechanisms that occur together.
However, after a certain period of time, e11800 mass loss rate of A P22 became greater than that of A B. However, the materials of pipes carrying two-phase flow should be selected considering their susceptibility to LDIE. Very s1180 sulfur content steels will produce too faint an image to be e1810 for macrostructural evaluations. Selection of appropriate printing practices including selection of type of emulsion coated media, acid type and strength, will yield satisfactory prints.
In nuclear power plants, carbon steel piping having experienced wall thinning degradation is generally replaced with low-alloy steel piping.
No other units of measurement are included in this 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 layer of magnetite on the surface of A asstm thicker than that of A P22, due to the different amount of chrome content.
ASTM E – 08 Standard Practice for Preparing Sulfur Prints for Macrostructural Evaluation
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. 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.
The sulfur print complements macroetch methods by providing an additional procedure for evaluating the homogeneity of a steel product. Steels with compositions that produce predominantly titanium or chromium sulfides will not produce useful images. 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.
Very faint images in the sulfur print can be made more visible astj scanning the sulfur print into a PC, and using a photo editor to increase the color saturation.
