Problems solved by technology

[0004] The main factors affecting the accuracy of Leeb hardness measurement are: the displacement or springing of the specimen during the measurement, which consumes the elastic potential energy stored in the specimen during the impact process, especially the mass of the specimen is too small and the overall rigidity is poor Wh

Abstract

The invention discloses a Leeb hardness tester clamping device for pipe hardness testing. The clamping device is mainly composed of three parts: a pipe clamping and fixing part, a Leeb hardness tester fixing part and a hardness tester sliding track block along the pipeline axial direction . The device can firmly fix the Leeb hardness tester on the pipe to be measured, and provide good support for the pipe to prevent relative displacement or springing during the measurement from affecting the measurement accuracy. At the same time, the Leeb hardness The gauge moves strictly along the axial direction of the measured pipeline, which is convenient for research and analysis. The device can effectively improve the measurement accuracy of the Leeb hardness tester.

Description

technical field [0001] The invention relates to the field of measuring the Leeb hardness on the outer surface of a pipeline, in particular to a clamping device for a Leeb hardness gauge for pipeline hardness testing. Background technique [0002] Nowadays, the single unit capacity of thermal power plants continues to increase, the main steam pressure of ultra-supercritical units reaches above 26MPa, and the temperature exceeds 570°C. Therefore, higher requirements are put forward for the material properties of various parts of the generating unit. In the infrastructure and service process of thermal power plants, it is particularly important to carry out physical and chemical inspections on the quality of pipelines. Due to limited conditions, hardness testing is the main testing method, supplemented by metallographic testing. Due to various limitations of the portable Brinell hardness tester, Leeb hardness testing is mainly used for on-site hardness testing. [0003] Leeb h...
