1. space-saving: pipe conveyor belt can transport materials along the bend layout, so that it's suitable for rugged and inregular shape fields to save space and energy.

2. prevention the scattering: materials are enclosed in the tubular shape conveyor belt to prevent scattering and leakage, avoid environment pollution and reduce the waste of spilled materials.

3. protection the materials: materials are almostly not affected by temperature, humidity, rains, snow and wind.

4. reduce the cost of transportation: pipe conveyor belt can convey materials back and forth, reducing the transportation cost and time.
