| Abstract: | Based on the results achieved from Malaysian Rosen Company's inspection on Fujiamiao-Naxi natural gas transmission pipeline with the magnetic leakage instrumented pig,the available corrosion status of the pipeline were analyzed.Corrosion defects on Fujiamiao-Naxi pipeline were repaired by replacing pipeline sections and using composite repair technique.There are 377 repaired points in total,and this project ensures security of the pipeline operation.In the construction process,experience and methods about defects locating,surface treatment technique and defects repair are summarized. |
