Embodiment 1

[0045] use as figure 1 , 2 As shown in the pipeline erosion corrosion test device, the sample loading rod is inserted into the loading hole of the blade-shaped structure at the through-slot bifurcation, and then passes through the inner tightening nut, the sample and the inner tightening nut in sequence, and the sample is fixed in the test. The sample loading rod is in the middle. Then fix the sample loading rod on the main screw through the outer tightening nut. The sample loading device that completes the sample fixation is screwed into the access port of the sample loading device of the fluid pipeline of the pipeline erosion corrosion test device. After screwing in, the orientation of the sample is adjusted according to the orientation of the top of the main screw to meet the test requirements. .

[0046] After the sample loading device is screwed into the pipeline, it is determined that the direction of the sample is at an angle of 180° to the direction of the water flo...

Abstract

The invention relates to a sample loading device for pipeline erosion corrosion test. Positioning nut, the other end of the main screw is provided with a middle through slot, and the upper part of the middle through slot structure is an arc structure. After the main screw is screwed into the fluid pipeline, the main screw is fixed by tightening the fixing nut. The two sides of the other end are respectively formed with blade-shaped structures through the central through slot, and the two blade-shaped structures are respectively provided with corresponding loading holes, and the two sample loading holes allow the sample loading rod to pass through and be fixed therein. The invention also relates to a pipeline erosion corrosion test device including the sample loading device. The invention can meet the needs of the pipeline scouring corrosion test, conduct accurate quantitative analysis and surface state observation and other scouring corrosion behavior evaluation on the sample, and is suitable for the pipeline scouring corrosion research.

Description

technical field [0001] The invention belongs to the technical field of corrosion test, in particular to a sample loading device used for pipeline erosion corrosion test. Background technique [0002] Erosion corrosion is one of the more common failure factors in reactors or pipelines of petrochemical production plants. The synergistic effect of corrosion and scouring makes the material more prone to damage, especially under a certain temperature, pressure and strong corrosive system, it is very easy to cause equipment failure. Therefore, the evaluation of corrosion factors, material evaluation or corrosion behavior research according to the working conditions plays an important role in the protection and prediction of erosion corrosion. In the method of scouring corrosion research, it is necessary to use the simulation device built by the laboratory small test research. According to the research experience in the industry, the rotating disk, pipeline and jet are the most co...
