Abstract

The mains reasons for internal corrosion failure and cracking of the tee in shale gas transportation platform have been proposed based on macroscopic analysis, physical and chemical property test, metallographic examination, Scanning Electron Microscope analysis, X-ray spectroscopy analysis and service condition analysis. The results show that corrosion occurring in the inner wall of tee was caused by the combined impacts of CO2 corrosion, sulfate-reducing bacteria (SRB) corrosion and erosion corrosion. The crack in the weld of the inner wall was mainly due to the Sulfate-reducing Bacteria Induced cracking.
