ANALYSIS OF FIBRE GLASS REINFORCED FLEXIBLE PIPES UNDER INTERNAL PRESSURE

Abstract

Abstract: A short-term burst pressure test is carried out and a 3D finite element model is established. An analytical solution of burst pressure of FGRFP is presented in the paper. The comparison of three methods shows that the stress of reinforced layers is much greater than that of inner and outer layers, indicating that the reinforced layers bear most of internal pressure. For the winding angle ranging from 45 to 80 degrees, the capacity to bear the internal pressure increases. The winding angle of 59 degrees of the reinforced layers is appropriate for the crossing section design. It is reasonable to reduce the diameter to thickness ratio of pipe for designing FGRFP.

Key words: fibre glass reinforced flexible pipes, internal pressure, short-term burst pressure test, FEM, analytical solution
