The invention discloses an axial load bearing composite material pipeline self-pressurization connecting method which comprises the steps that A, a limiting ring is installed on the inner side of an inner pipe, specifically, the limiting ring is located at the connecting position of the inner pipe and an outer pipe, and B, acting force is applied to the outer surface of the inner pipe to enable the inner pipe to deform inwards, and meanwhile acting force is applied to the inner surface of the outer pipe to enable the inner pipe to deform inwards. C, placing the joint of the inner pipe on the inner side of the outer pipe, D, fixing the part, close to the joint, of the inner pipe by using a fixer, and E, driving a heater to heat the inner pipe to restore the original shape of the inner pipe, and meanwhile, transferring heat to the outer pipe through the inner pipe to restore the outer pipe to the original shape. And F, after the inner pipe and the outer pipe completely recover to the original ...
