Abstract

The invention discloses a high-temperature and high-pressure steam pipeline elbow hardness measuring point positioning detection device, and belongs to the technical field of pipeline elbow hardness detection. The device comprises a first sliding rail, a second sliding rail and a pipeline elbow, and the side, away from the pipeline elbow, of the first sliding rail is provided with a T-shaped sliding groove; and a first sliding groove is formed in the side, away from the first sliding rail, of the second sliding rail. The positions of the first sliding rail and the second sliding rail are adjusted, then the position of a sliding mechanism is adjusted and positioned, the hardness detection point can be accurately positioned, due to the fact that the detection positions are the same every time after accurate positioning, the hardness value detected every time has traceability, the detection value can be compared with a previous detection value, therefore, the hardness value of the high-temperature and high-pressure steam pipeline elbow can be supervised for a long time, so that the change condition of the hardness value of the elbow is known, and the operation condition is mastered.

Description

technical field

[0001] The invention belongs to the technical field of pipeline elbow hardness detection, and specifically relates to a high-temperature and high-pressure steam pipeline elbow hardness measurement point positioning detection device. Background technique

[0002] Hardness is one of the most commonly used indicators to evaluate the mechanical properties of metal materials. The on-site hardness test value is of great significance to the safety status evaluation of high-temperature and high-pressure steam pipelines. Therefore, the hardness test value of high-temperature and high-pressure steam pipelines requires extremely high accuracy. The hardness of the elbow / bend of the high-pressure steam pipeline is uneven during the preparation process, which leads to a certain difference in the hardness value of the elbow / bend at different positions when it leaves the factory, and each time the on-site inspection, due to various reasons , the location of the hardness meas...
