The invention discloses a vacuum low-temperature tank making natural gas convenient to transport. The vacuum low-temperature tank comprises a tank body, wherein the tank body comprises an inner container and an outer tank body; the top of the outer tank body is provided with a gas inlet, a vacuum gas extracting port, a pressure reducing valve and a gas outlet, and the vacuum gas extracting port isconnected with a vacuum pipe; reinforcing ribs are arranged between the outer tank body and the inner container, a cold pipe coils around the outer sides of the reinforcing ribs, and a heat insulation and heat preservation layer is arranged outside the reinforcing ribs and the cold pipe; and a cold pipe connector is arranged on the side face of the outer tank body, a lifting frame is arranged onthe periphery of the outer tank body, and a damping base is arranged at the bottom of the outer tank body. According to the vacuum low-temperature tank, the defect that a pipeline cannot convey the natural gas to remote mountain villages or places with severe environment is overcome, and therefore the natural gas can be used by people all around the country; and the reinforcing ribs are arranged,and therefore the tank can bear high vacuum and can also bear the inertia force under a transportation working condition.
