Composite pipes design considerations

This method is often chosen when there is adequate evidence that suggests the remaining thickness of the pipe is still significant. In this case, contribution of the remaining thickness of the pipe is considerable. The desired outcome of the design as mentioned previously is the minimum thickness of the composite wrap that reinstates its capacity to the original noncorroded capacity. Design parameters required are the equivalent axial force, the equivalent internal pressure, the live pressure, the tensile modulus of steel and composite and the allowable stress of steel.
