Problem: In the lower third, in which the belt slides on the steel tube, the two tubes of the tubular conveyor were partially so worn that large holes were created. This not only damaged the structure of the pipe, but also allowed the air film to escape, which should be present as a sliding film between the steel pipe and the conveyor belt.The pipeline is over 100 m long. Accessibility, especially in the lower tube, is extremely difficult.
Photograph Descriptions

  3. Reinforcement plate positioned
  4. Finished repair point in the lower tube

Belzona Facts
Completed repair at the beginning of the pipeline. The Belzona product in this area extends beyond the steel level as the steel will wear out relatively quickly. It was agreed that additional rollers would be installed that would protect this area from the massive abrasion load.
