The Research about the Strength of Composite Riser Pipes Based on Finite Element Method

Abstract:

Composite riser pipes are being paid more and more attention because of its lightweight and high strength comparing with the steel riser pipes. It mainly includes internal liner, elastic shear layer, structural composite overlap layers, external protective sleeve and additional composite layer and so on. In this paper, the mechanical analytical model of composite riser pipe is constructed. The equivalent material properties are obtained in the globe analysis, and from the local analysis, it found that the helical layers mainly bear bend loadings, and the hoop layers mainly bear internal pressures from the simplified composite joint local analysis. It is proved that the composite riser pipe has the excellent designability.
