Floating Hose

Overview

Dredging floating hose is equipped with PE foam body, adjusted to the buoyance of the dredged material, usually used with dredgers for silt/gravel conveyance. Besides, it has good flexibility for the most challenging working environments. It can withstand wind, and waves and is suitable for the harshest sea or mining conditions. 

  • Strong flexural properties performance
  • Outer cover with excellent abrasion resistance and UV protection.
  • The suitable working temperature: from -20℃ to +50℃.

Structures of floating dredging hose

Equipped with PE foam body, adjusted to the buoyance of the dredged material.
When we design the buoyancy of the floating hose, the reserve buoyancy is generally 20%.

The above are some regular sizes, we can also customize specifications according to customer needs.

Due to the different dredging conveyance, we usually have different requirements for the wear resistance of the rubber hoses. 

In order to meet the requirements of different dredging projects, our floating hoses are lined with rings or ceramics in the internal structure to improve wear resistance. You can choose the appropriate hoses according to your needs.

Floating Hose

The conventional floating hose is our most commonly used discharge hose in dredging, which is suitable for most dredging projects. The suitable conveyance matters them are usually mud, clay, fine sand, fine-mid sand, and so on. 

Armoured Floating Hose

Armored floating hose has rings in the internal structure, which make it have good wear resistance. It is usually used for dredging sharp materials which have bigger volumes, and heavy specific materials like coarse sand, coral reef, or weathered rock.

Ceramic Floating Hose

Ceramic floating hose’s inner structure has ceramic pieces that make hoses have better wear resistance. They are suitable for the harshest sea or mining conditions. Compared with armored floating hoses, they have better wear resistance but are also more expensive.

Our manufacturing and testing of dredging hoses are strictly in accordance with ISO 28017-2011 Standard.
If you have other dredging needs, we also provide customization of dredging rubber hoses.
