Description

technical field [0001] The invention relates to the technical field of erosion corrosion devices, in particular to a speed measuring anti-settling erosion corrosion test device and a test method thereof. Background technique [0002] During the transportation of oil and natural gas, since oil and gas will carry solid particles, it is very easy to cause erosion corrosion. Erosion is the impact effect on the substrate when the fluid flows through the metal surface, and the solid particles in the fluid will also impact and wear the metal substrate. Corrosion is the electrochemical reaction on the metal surface, resulting in the loss of metal materials into the fluid. The laboratory usually uses a rotary erosion corrosion tester for experimental research, which has a simple structure and is easy to operate. However, the disadvantages are serious settling, the inability to measure the relative velocity of the sample and the fluid, and the lack of effective regulation of the test...
