Abstract

Abstract:

Flaws on the long distance oil-pipe are one of the invisible big problems which will result in abnormal work. With the finite element method, the longitudinal flaws on pipe wall were analyzed in this paper, the distribution rule of stress at the flaw was obtained, and the influence of the length, width and thickness of the wall on the stress was analyzed. The results can be used to the design and safety management of the pipe.

Key words: finite element method, stress analysis, corrosive flaw
