DREDGING SUCTION HOSE

For use in floating or fixed pipelines. To handle fine and coarse-grained materials with high vacuum loads.

Applications: Wet dredging, sand and gravel excavation, suction dredging and gravel washing systems.

Construction:

  • Highly abrasion-resistant tube
  • Tension and pressure-resistant special fabric inlays
  • Concealed steel spiral
  • UV, ozone and weather-resistant, abrasion-resistant cover
  • Interior smooth, exterior corrugated

HIGH-VACUUM DREDGING HOSE

For use as an expansion joint in suction and pressure lines. As a suction hose on suction dredgers with narrow bending radiuses. To handle fine and coarse-grained materials. Also suitable for tough transport applications of dry materials in the mining field.

Construction:

  • Highly abrasion-resistant tube
  • Tension and pressure-resistant special fabric inlays
  • Concealed steel rings
  • UV, ozone and weather-resistant, abrasion-resistant cover
  • Interior smooth, exterior deep corrugated
