摘要:
为了进一步做好天然气长输管道的防腐工作,保证管道输送的安全性和可靠性,对不同地理环境下埋地管道的腐蚀机理及腐蚀原因进行了分析,并针对不同的腐蚀机理给出了相应的检测方法。管道外防腐一般采用外防腐层加阴极保护的联合防腐方式,可采用电流电位检测法、密间隔电位检测法、人体大地电容检测法、直流电压梯度检测法、多频管中电流检测法等方法来检测埋地管道的外部腐蚀情况。在役管道内腐蚀的检测难度较大,建议在原有超声波检测和漏磁通检测的基础上,进一步开发新的检测方法,以期达到更好的检测效果。
Abstract:
In order to further improve corrosion prevention of long-distance natural gas pipeline to ensure the safety and reliability of pipeline transportation, corrosion mechanism and reasons of the buried pipeline in different geographies were analyzed, and detection methods for different corrosion mechanisms were given. The external corrosion protection combined with cathodic protection was commonly used for external pipeline anticorrosion, and external corrosion detection method of buried pipeline included current-potential method, close interval potential measurements, human-earth capacitance survey, DC voltage gradient method and tube current method. Because of the difficulty of internal corrosion test on service pipeline, a new detect method based on ultrasonic detection and leakage flux detection should be developed to achieve better detect effects.
