The pipes' leak is an important problem in industry for technicians or operators. As assuming the inner liquid is static liquid in this paper, pipes' linked pre-stress has an important effect on pipes' leak. Through a theory deduction and FEM analysis, the numerical example is shown that this method is accurate and very useful for practice finally.
