The invention relates to a vacuum low-temperature insulation pipe for transferring low-temperature fluid, in particular to a compensator-less vacuum low-temperature insulation pipe for transferring low-temperature fluid. The vacuum low-temperature insulation pipe comprises an inner pipe (2) for transferring low-temperature medium and an outer pipe (3) sleeved on the inner pipe (2), wherein the inner pipe (2) is wrapped by thermal insulation material, moreover, vacuum is formed between the inner pipe and the outer pipe, pipe supports (4) are evenly arranged between the outside of the inner pipe (2) and the inner wall of the outer pipe (3) along the axis of the outer pipe (3), the central section of the inner pipe (2) or the outer pipe (3) is of a curved structure between each two pipe supports (4), and furthermore, the curving directions of the inner pipe between neighboring pipe supports (4) are opposite. By ingeniously design the inner pipe and the outer pipe, the invention ensures that the compensator-less vacuum pipe has little heat loss and is safe, stable and efficient when transferring low-temperature fluid.
