高压锆钢复合板设备热气循环试验参数研究

Research on Hot Gas Cycle Test Parameters of High Pressure Zirconium Steel Clad Plate Equipment

热气循环试验是用于锆(钛)钢复合板制压力容器的一种检测方法,该方法能够大大提高该类设备的使用可靠性,保证设备长期安全稳定的运行。但由于部分设备的设计压力过高,采用通用的设计压力和设计温度作为试验参数进行热气循环试验比较困难,且安全隐患较大,更有甚者在某些地区的制造单位还禁止使用过高的气压试验进行设备可靠性测试。因此,本文从热气循环试验的目的出发,采用一种可替代的试验参数进行该试验,通过某项目实例进行计算验证能够达到相同的效果,具有良好的经济性及安全性。

The hot air cycle test is a detection method used for zirconium( titanium) steel clad plate pressure vessels.This method can greatly improve the reliability of this type of equipment and ensure its long-term safe and stable operation.However,due to the high design pressure of some equipment,it is difficult to use universal design pressure and design temperature as test parameters for hot air cycle testing,and there are significant potential safety hazards.Even in some regions,manufacturing companies also prohibit the use of excessively high air pressure tests for equipment reliability testing.Therefore,starting from the purpose of hot gas cycle testing,an alternative test parameter is adopted to conduct the test in this paper.Through calculation and verification of an example in a certain project,the same effect can be achieved,but it has better economy and higher safety.
