Industrial Pipe Conveyor Belt avoids pollution by preventing falling or spillage of carried products. The Pipe Conveyor Belt also avoids damage to belt inner surface, as fallen objects do not attach to belt surface. The Pipe Conveyor Belt reduces abrasion between the products and inner belt surface which increases when conveyor belts are in pipes, enabling greater transportation degree than other commonly used belts. Industrial Pipe Conveyor Belt prevents other substances from entering, assuring purity of products.
