The maximum corrosion depth of pipe is acquired through measuring stochastically corrosion pit depth of pipe on the surface and using probabilistic method. According to cases of ASME code, the residual life of corrosion pipe is assessed.

• 通过随机实测管道表面的腐蚀凹坑深度，并采用概率统计的方法得到了管道最大腐蚀深度，然后参照ASME规范的有关准则进行了管道的腐蚀剩余寿命评估。
