Pipe conveyor belt is a new type of conveying belt which uses high tenacity canvas EP/NN or steel cord as carcass, high elastic, high anti-abrasive and high strength rubber as working surface. It’s mainly used in conveying materials which are easily polluted like power, granular materials, etc. when working, the rubber belt changes its form from flat to U shape and finally to pipe, folding the materials and realizing the process of enclosed conveying. Enclosed conveying of materials, protecting both the materials and the environment.

Cover properties | Tensile strength | Breaking elongation | Abrasion loss | Anti ozonea | Change rate of tensile strength & breaking elongation after hot air ageingb, % |
D | 18.0 | 400 | 90 | No crack | -25~+25 |
H | 24.0 | 450 | 120 | No crack | -25~+25 |
T1、T2 | 10.0 | 300 | 200 | - | -45~+45 |
a. Anti ozone testing conditions: concentration (50±5)×10-8 (volume fraction), temperature (40±2)℃, elongation (40±2)%, time 96h.
b. Hot air ageing testing conditions: D, H type belt 70℃×168h; T1 type belt 100℃×168h; T2 type belt 125℃×168h. |
Note: D—high abrasion working conditions; H—high tear working conditions; T1—Heat resistance 100℃ working conditions; T2—Heat resistance 125℃ working conditions. |
