GB/T 34349-2017
ActiveExternal inspection methodology for internal corrosion of natural gas pipelines
输气管道内腐蚀外检测方法
Application Summary AI generated
This standard specifies the technical requirements for externally assessing internal corrosion in natural gas pipelines without direct internal inspection. It is applied in the oil and gas industry for in-service pipeline integrity management, using non-destructive techniques such as magnetic flux leakage or ultrasonic testing from the pipe's exterior. The methodology helps operators evaluate corrosion severity, prioritize maintenance, and ensure safe transport of natural gas.
