腐蚀管道最小壁厚测量和安全评价方法
Measurement and Safe Assessment of Depth of Co rroded Pipeline
-
摘要: 介绍了埋地钢质管道管壁损失的测量方法, 提出了适合现场使用的管道安全评价模式, 该模式分为三个层次, 依次为管道最小壁厚、危险截面尺寸和管道残余强度的评价, 给出了管道安全评价实例。Abstract: The measurement of residual depth of corroded steel pipeline is introduced, and the safe assessment is studied, which has three steps, based on minimal residual depth and size of hazard section (CTP) and residual stretch factor (RSF), respectively.
