This utility model relates to a seamless steel pipe for ultra-low temperature alloy structures with rust-proof function, comprising a steel base pipe, an outer wall of which is provided with a corrosion-resistant layer, an outer layer of which is provided with a water-proof layer, and an outer layer of which is provided with a wear-resistant layer. This seamless steel pipe for ultra-low temperature alloy structures with rust-proof function comprises, from the inside out, a steel base pipe, a galvanized metal layer, a fiber reinforcement layer, a water-proof layer, and a wear-resistant layer. The galvanized metal layer is hot-dip galvanized and directly adheres to the surface of the steel base pipe, filling the microscopic defects of the matrix and making the pores smaller. The fiber reinforcement layer is a glass fiber braided layer, with the glass fiber braided layer interlaced at 45° and bonded to the galvanized metal layer with epoxy resin. The mesh skeleton is a nylon mesh, and the water-proof adhesive layer is a butyl rubber / polyurethane composite adhesive. The nylon mesh is embedded in the middle of the water-proof adhesive layer, which can enhance the shear deformation resistance of the water-proof layer.
