DN550 Dredge Self Floating Rubber Hose

DN550 Dredge Self Floating Rubber Hose

Application
DN550 dredge self floating rubber hose is widely used for dredging.It can float on the water under working condition.The dredge self floating rubber hose is suitable for the water with high wave and narrow water area. The self-floating capability of the hose is achieved through the use of closed-cell foam flotation devices that are integrated into the hose's structure. These flotation devices are placed at intervals along the length of the hose and ensure that it remains afloat and above the water surface, even when fully submerged.

Features
1.Outer cover with excellent abrasion resistance and UV protection.
2.Inner layer  with excellent abrasion resistance and high quality.
3.Single foam flotation casing to prevent water absorption.
4.Wearing colored indicator layer.
5.area above water not less than 20% of total volume.
6.Bending angle: in working condition,the bending angle is from 0°to 45°.
7.Low center of gravity,strong anti-wave ability,good stability.
8.Easy installation,good adhesion,long service life.
9.The product can be customized according to clients' requirements.

Structure and Material
1.Inner rubber layer: NR,SBR or BR.
2.Reinforcement layer: tire cord with helix wire and floating material layer.
3.Floating layer: PE.
4.External rubber layer: SBR and CR blend.
5.Safety factor: 1:3.
