摘　　要：磁力层析检测技术是最新的埋地钢制管道检测技术,它通过对铁磁性材料的磁记忆特征的记录,来实现在非开挖的情况下对管道管体的检测。应用该检测技术在城市燃气管道上实施检测,通过本次检测管道管理方掌握了管道的管体腐蚀状况,并且通过对管道进行开挖,验证了该检测技术的可行性、准确性和可靠性。该技术的实践应用不但提高了检测人员对检测技术的理解,实现新技术与管道检测业务的有机结合,同时也为管道安全运行提供有利技术保障。Magnemetric tomography method technology is the latest detection technology for buried steel pipeline, through ferromagnetic metal magnetic memory feature records achieved in the case of non- excavation pipeline inspection.That implemented on the city gas pipeline inspection, through this detection pipeline management master corrosion status and pipeline excavation, verify the accuracy and reliability of this technology. The practical application of this technology not only improves the understanding of testing personnel on the detection technology, achieving the organic combination of new technology and company pipeline inspection, but also provide an enabling technology guarantee for the safe operation of the pipeline.
