摘要
介绍导向型超声波技术 (GWUT)检测埋地带套管短管段内金属管道壁厚损失的原理、设施、特性和检测效果。该技术提供一种低成本检测方法 ,可满足管道完整性计划中直接评价的要求。对于无法用清管器检测的管段特别有用。
Principle,equipment,performance feature and sensitivity of the Guided Wave Ultrasonic Technique(GWUT)for corrosion detection of sleeved pipeline buried underground were introduced.This technique offers a low-cost detection method,with which the direct assessment requirement can be met in the pipeline integrity program,that is especially useful for unpiggable pipe sections.
