“…[5][6][7][8][9] The tubing which serves in a high salinity solution with hightemperatures and high-pressures can undergo severe general corrosion or localized/pitting corrosion. [10][11][12][13][14][15] 13Cr stainless steel has been proved to have the good corrosion resistance in CO 2 environments as long as the temperature is lower than 150 C, 16 and also a higher strength and a lower cost than the other CRAs such as duplex stainless steels. 10,17,18 A lot of researches have studied the corrosion resistance of 13Cr stainless steel and the effect of temperature, chloride ion, and sulphide ion on the passive lm stability of 13Cr steel in CO 2 environments.…”

The black-water regulating valve is very easy to be damaged due to the erosion of the key components, such as valve spool and valve seat. This work presents the failure analysis of the spool and seat of regulating valve in the black-water treatment system. Scanning electron microscopy (SEM) and X-ray energy dispersive spectrometer (EDS) were used to detect the morphology and chemical compositions of failure valve samples. The computational fluid dynamics (CFD) method was also adopted to simulate the medium flow characteristics in black-water regulating valve. The results show that most erosion areas of the valve occur at the spool-seat throttle zone. The erosion profile is mainly manifested in plastic deformation pits, cutting abrasions, furrows, pinhole pits and impact pits. The particles and cavitation bubbles move toward the throttle zone driven by black-water medium, causing particles impact and bubbles collapse. The valve suffered severe particle erosion and cavitation erosion under the particle impact and bubble collapse, finally resulting in its failure.

“…e authors believe that carbonate-bicarbonate-induced stress corrosion cracking is the main cause of rupture and leakage of buried pipelines. Long et al [12] others used a direct-reading spectrometer, Rockwell hardness tester, optical microscope analyzer, scanning electron microscope, energy dispersion spectrometer, electrochemical method, and finite element method to analyze the failure of a tubing pump. e authors believe that higher concentrations of down hole media CO 2 and Cl − are the environmental factors of damage, and the alternating stress caused by the cyclic movement of the pump is the main stress factor of the damage, and the high stress concentration of the threaded joint further causes cracking.…”

When a wellhead gas production tree in a certain oilfield block fracturing completed 12 layers and 22 layers and then the bottom-up discharge operation was performed, the Wellhead four-way suddenly suffered erosion failure. This is the seventh failure of this operation. In order to obtain the cause of failure, the chemical analysis, hardness testing, tensile property testing, and finite element structural dynamic analysis are used to analyze the failure of the cross connection. The results of physical and chemical analysis show that the chemical composition, hardness, and tensile properties of the failed parts meet the requirements of the standard, not the problem of the material of the work piece. Due to the high-frequency vibration generated by the three-phase fluid in the pipeline during the discharge process, different types of vibration and deformation of the four-way valve and the valve body occur. The dimensions of the on-site structural parts were measured, and the bolt sizes were found to be different. A finite element model was established based on the measured data for dynamic analysis. Through physical and chemical tests and theoretical calculations, it is found that the cause of failure is the unbalanced load and resonance of the bolt, and the nut undercuts under high-frequency vibration, which causes leakage at the flange connection and eventually causes erosion failure. It is recommended to regularly use an electronic torque wrench to test the pretightening force of each bolt to prevent vibration and failure due to inconsistent pretightening force of the bolts.
