The invention discloses a mooring pipe. The shapes of an inner-layer shell and an outer-layer shell of the mooring pipe are manufactured through simulating the outline curve of a goose egg, steel balls serving as rollers in a friction reducing device are embedded between the inner-layer shell and the outer-layer shell, and the steel ball rollers are lubricated. The mooring pipe of the structure has the advantages of being smaller in size, free from reinforcing ribs, good in mechanical property and the like, and the mooring pipe is internally provided with a mechanism used for reducing the friction between the mooring pipe and a mooring rope, and the mechanism can be lubricated.
