Pipe crack manufacturing system

The invention belongs to the technical field of nuclear power, and particularly relates to a pipe crack manufacturing system. According to the pipe crack manufacturing system, different pipeline real service environments such as a corrosive medium environment, a high-temperature environment and fatigue pressurization can be simulated according to needs, and therefore real fatigue cracks of pressure-bearing pipes under different pipeline service part replacement can be manufactured. In addition, the loop of the corrosive medium is isolated from the loop of the pressurization system so that the generation of real fatigue cracks of the pressure-bearing pipe under a high temperature or the corrosive medium is realized, and the damage of the corrosive medium to pressurization equipment is avoided. 本公开属于核电技术领域，具体涉及一种管材裂纹制作系统。本公开的管材裂纹制作系统能够根据需要模拟诸如腐蚀介质环境、高温环境、疲劳加压等不同的管道真实服役环境，由此可以制造出不同管道服役换件下承压管的真实疲劳裂纹。此外，本公开将腐蚀介质的回路与加压系统回路相隔离，既实现了高温或腐蚀介质下，承压管的真实疲劳裂纹的产生，又避免了腐蚀介质对加压设备的损坏。
