Failure Analysis on Pipe Body Fracture of S135 Drill Pipe in West-East Gas Pipeline for Direction Crossing
The S135 drill pipe occurred failure accident for direction crossing rive during West-East natural gas transmission In order to analyze the failure reason,this paper carries on the overall analysis to the drill pipe sample based on the magnetic particle testing,fractography,and metallography,et.al.The analysis discovers that: the fracture has many cycle cracks and the sulfur content in the lateral fracture is higher than that in the other area of the drill pipe.The cracks show the typical characteristic of hydrogen sulfide stress corrosion cracking.It concludes that the fractures are hydrogen sulfide stress corrosion cracking.The drill pipe with anti-hydrogen sulfide property should be used and the drill pipe should be stored for a period before using in this oil field.
