The stainless steel pipe is a hollow long-strip round pipe and is mainly widely used for industrial conveying pipelines, mechanical structural parts and the like in petroleum, chemical industry, medical treatment, food, light industry, mechanical instruments and the like. When water is transported through a stainless steel pipe, the phenomenon of water hammer caused by sudden change of the flow velocity of water due to some external reason is called water hammer. Intraductal water can strike nonrust steel pipe inner wall at first when the water hammer produced, vacuum area can appear in the intraductal afterwards, and outside atmospheric pressure can exert pressure to nonrust steel pipe outer wall, if the compressive capacity of pipeline is relatively poor, the impact force of water and outside atmospheric pressure will cause nonrust steel pipe to warp to lead to the appearance of seepage phenomenon. In order to avoid deformation caused by water hammer in the use process of the stainless steel pipe, the stainless steel pipe needs to be subjected to compressive strength detection before leaving a factory so as to ensure that the finished stainless steel pipe leaving the factory does not deform within a specified pressure range.
When the water hammer phenomenon actually occurs, the whole annular inner wall or outer wall of the corresponding position on the pipeline is under the action of pressure, but when the existing detection device is used for carrying out compression resistance detection on the stainless steel pipe, only a single point on the stainless steel pipe can be pressed, the actual working scene cannot be accurately simulated, and the detection accuracy is poor; in the existing detection process, whether the pipeline is deformed or not is mostly judged by observing the surface of the pipeline by naked eyes of a detector, but because the pipeline is circular, when the surface of the pipeline is slightly deformed, obvious deformation such as folds or edges and the like cannot be generated, so that the pipeline is not easy to be observed by the detector, and the accuracy of a detection result is also reduced; there is also a common method of providing a pressure sensor on the surface of the pipe, and when the pipe deforms, the pipe generates pressure to the sensor, and the sensor sends a signal, but this method requires a plurality of sensors around the pipe, which is costly.
