摘要
应用声发射检测技术,对三台层板包扎高压容器进行了试验研究及解剖对比。研究了层板包扎高压容器声发射检测技术工艺,建立了检测结果评价准则。应用该方法检测国内80余台尿素合成塔,发现了大量裂纹类缺陷,验证了层板包扎结构尿素合成声发射检测技术的有效性。
Through experimental investigation and destructive comparision for three multilayer wrapped high- pressure vessels using acoustic emission method,an acoustic emission testing technology of multilayer wrapped pressure vessels was studied and the evaluation criterion of testing results were established.The method was applied to 80 urea reactors and many crack flaws were found.These applications showed that acoustic emission testing technology of multilayer wrapped urea reactors was effective.
