Abstract

The invention provides a method and apparatus for testing the high temperature fluid erosion corrosion resistance of a material, and belongs to the field of experiments. The method for testing the high temperature fluid erosion corrosion resistance of the material comprises the following steps: selecting at least one metal material, and placing the at least one metal material in a flowing experiment flow medium, wherein an angle between the at least one metal material and the flow direction of the experiment fluid medium is adjustable, and the temperature and the speed of the experiment fluid medium are adjustable. The apparatus for testing the high temperature fluid erosion corrosion resistance of the material comprises a box body, a stirring driver and a material mounting rack, the box body is used for accommodating the high temperature experiment fluid medium and can be sealed, the stirring driver can drive the experiment flow medium to flow, the material mounting rack is used for mounting the test material, and the test material is placed in the experiment flow medium. The method and the apparatus can fully simulate erosion corrosion of the practical high temperature fluid to environment in order to objectively evaluate the high temperature fluid erosion corrosion resistance of the metal material.

Description

technical field [0001] The invention relates to the field of experiments, in particular to a method and a device for testing the erosion and corrosion resistance of materials against high-temperature fluids. Background technique [0002] In recent years, the deterioration of crude oil has become more and more serious, and the content of harmful substances that corrode refining and chemical equipment in crude oil has become higher and higher. With the large-scale and refined equipment, the flow state of harmful substances in the equipment has become more and more complicated. Severe erosion and corrosion often occur in high-temperature parts of equipment and pipelines, causing unplanned shutdowns, affecting economic benefits, and posing a serious threat to production safety. [0003] In the prior art, the experimental means adopted are, for example, by setting a medium container higher than the experimental container, so that the experimental medium circulates between the med...
