This paper presents a comparison of the mass loss rate of the tested awtm between carbon steel A B and low alloy steel A P22 resulting from degradation effect. Very faint images in the sulfur e180 can be made more visible by scanning the sulfur print into a PC, and using a photo editor to increase the color saturation.

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

Referenced Documents purchase separately The documents listed ee1180 are referenced within the subject standard but are not provided asrm part of the standard. Selection of appropriate printing practices including selection of type of emulsion coated media, acid type and strength, will yield satisfactory prints. The sulfur print complements macroetch methods by providing an additional procedure for evaluating the homogeneity of a steel product.

The magnetite is formed by controlling the water chemistry and the temperature of fluid inside the facility. However, the materials of pipes carrying two-phase flow should be selected considering their susceptibility to LDIE.

ASTM E1180 – 08(2014)

In the initial stage of the experiments, the mass loss rate of A B was greater than that of A P 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.

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

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. 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.

No other units 1e180 measurement are included in this standard. For specific precautionary statements, see Section 9. Very low sulfur content steels will produce too faint an image to asrm useful for macrostructural evaluations.

Scientific Research An Academic Publisher. An experimental facility was set up to develop a prediction model for clarifying multiple degradation mechanisms that occur satm.

It is the responsibility of the user of this standard to establish appropriate safety and health practices axtm determine the applicability of regulatory limitations prior to use. The experimental facility allows e11880 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. Historical Version s – view previous versions of standard.

The density of the print image should not be used to assess the sulfur content of a steel.

Link to Active This link will always route to the current Active version of the standard. The layer of magnetite on the surface of A is thicker than that of A Astk, due to the different amount of chrome content.
