目前我国使用的超高压人造水晶釜,运行参数大都为P(工作压力)=137MPa、T(工作温度)=380℃;材料为PCrNi3MoVA;在定期检验时拆除卡箍、釜口法兰和釜口密封塞等部件后,进行检测的釜体结构如图1所示。水晶釜一般有釜口台阶和釜底退刀槽台阶,该区域均为应力集中区,在定期检验中须作为重点检查区域。经检验实践的摸索,总结出以上二区域的无损检测方法。
At present, China’s use of UHP artificial crystal reactor, the operating parameters are mostly P (working pressure) = 137MPa, T (working temperature) = 380 ℃; material is PCrNi3MoVA; remove the clamp during the regular inspection, After the other components, to test the reactor body structure shown in Figure 1. The crystal kettle generally has a kettle mouth step and the tank bottom recess step, the region is stress concentration area, in the regular inspection to be as a key inspection area. After the test practice exploration, summed up the above two non-destructive testing methods.
