We study collective transport of polar active particles on the surface of a corrugated tube.Particles can be rectified on the surface of the asymmetric tube.The system shows different motion patterns which are determined by the competition between alignment strength and rotational diffusion.

For a given alignment strength, there exist transitions from the circulating band state to the travelling state, and finally to the disordered state when Ski de fond - Skis a roulettes continuously changing rotational diffusion.The circulating band is a purely curvature-driven effect with no equivalent in the planar model.The rectification is greatly improved in the travelling state and greatly suppressed Shoes - Sandals - Womens in the circulating band state.

There exist optimal parameters (modulation amplitude, alignment strength, rotational diffusion, and self-propulsion speed) at which the rectified efficiency takes its maximal value.Remarkably, in the travelling state, we can observe current reversals by changing translational diffusion.
