ABSTRACT:
A method for making a reinforced pipeline comprising determining the thicknesses of a metallic liner and a reinforcement which are effective to limit stresses on a reinforced pipeline at a known operating pressure to a known percentage of the specified minimum yield strength and a known percentage of at least one actual yield strength along the length of the pipeline which differs from the specified minimum yield strength. Preferably, the reinforced pipeline is pressurized to produce yielding which results in a residual stress pattern effective to resist ductile fracture propagation along a longitudinal axis of said metallic liner along a length of the pipeline comprising at least two actual yield strengths.
