The utility model relates to the technical field of pipeline plugging, and discloses a composite pressure-resistant pipe which comprises an outer sleeve, an inner sleeve and a plugging assembly, the outer sleeve is arranged on the peripheral side of the inner sleeve in a sleeving mode, the inner diameter of the outer sleeve is larger than the outer diameter of the inner sleeve, a plurality of segmentation section plates are arranged between the outer sleeve and the inner sleeve, and the plugging assembly is arranged between the outer sleeve and the inner sleeve. The outer casing pipe, the inner casing pipe and the segmentation segment plates define a sealed cabin, the plugging assembly comprises an inflation plug and a connecting pipe, the inflation plug is arranged in the inner casing pipe, and the sealed cabin is communicated with the inflation plug through the connecting pipe. When the pipeline is pressed, gas in the sealed cabin is pressed into the inflation plug in the inner sleeve, and when the pressure
