Dredging Hoses

The success of dredging operation depends on type and quality of delivery pipes and floaters that support the discharge line.

Dragflow provides two different types pipes:

  • Delivery flexible pipes: delivery flexible pipes, they are subjected to higher abrasion, but guarantee the most handling versatility during dredging operations.
  • Delivery surface pipes: the delivery surface pipes transport the material to the discharge place.

Dragflow offers both options according to customer-s needs and preferences.
