Application of In-pipeline Detection Technology in High Sulfur Gas Fields in Mountainous Areas
Due to the complexity of raw gas composition and transportation environment,the inner wall of the gathering and transportation pipeline in the high sulfur gas field in the mountain area will suffer from electrochemical corrosion and leakage risk,so it is very important to carry out internal detection of acid gas pipelines.Magnetic flux leakage(MFL)detection technology is a relatively mature internal detection technology used in high sulfur gas fields.In recent years,a new electromagnetic eddy current internal testing has been developed,which has good passability,high recognition of small size defects,and is more suitable for small diameter and low flow rate pipelines.Based on the application results of magnetic flux leakage(MFL)and eddy current(EDDy-current)detection technology in a high sulfur gas field,the field adaptability,advantages and limitations of the detection technology are analyzed,and suggestions for improvement are put forward to provide technical support for the selection of detection technology in the same type gas field in the future.
