Study on Optimal Winding Angle of Submarine Oil Flexible Pipe

Abstract:

According to the actual structure, using the finite element software ANSYS, numerical model of submarine oil flexible pipe was established. For the mechanical response of flexible pipe under the combined effect of internal pressure load and transverse load, the comparison on the result by numerical calculation and static loading test shows that the numerical model of flexible pipe is rational. Moreover, based on the numerical model of flexible pipe, this paper indicates that the maximum Mises stress occurs at the end of flexible pipe, which would lead to the bulge performance failure. Furthermore, the influence of winding angle on the mechanical properties of flexible pipe was analyzed, and the optimal winding angle 30° was suggested to adopt.
