| Abstract: | Drill pipe is the vital component of oil drilling string. Its bulging defect on inner wall would lead to failure or accident. A new method for bulging defect defection is demonstrated in this paper, which through component analysis of non-metallic or other inclusions in bulging based on metatlographic analysis and EDS analysis theory, and bulging detection by using uhrasonic flaw detector and ultrasonic thickness gauge. The drill pipe tested is a plain end pipe, dimension of which is φ 127×9.19 mm. The method for detecting bulging defect on inner wall of drill pipe is renaMe according to the research result. |
