DN800 Dredge Self Floating Rubber Hose

Application
The DN800 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. The hose is typically constructed with a reinforced rubber lining and multiple layers of high-tensile synthetic cord to provide strength and flexibility. The outer layer is made of rubber, which is resistant to oil, abrasion, and weathering, and is colored bright orange for high visibility on the water surface.

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.
