1. Brief Introduction of Dredge Floater:
The hull of MDPE floater is made from medium density polyethylene material with excellent flexibility, filled with high strength polyurethane foam inside. With reasonable structure and good performance, the MDPE floater becomes the ideal substitution of the traditional steel floater for the floating dredging pipes.
2. Main Features of Dredge floats:
1) Good flexibility, excellent impact resistance, particularly suitable for constructions in open sea;
2) Easy to install and handle, lower costs for moving;
3) Higher corrosive resistance, longer working life, 3 times longer than steel floaters;
4) Lower costs, the cost performance is better than steel floaters.
3. Applications:
1) Used in dredging sand pipeline;
2) It can be used in dredger, dredging pipe in the sea, lake or river and so on.
It’s usually connected with sand dredger or pump for discharge slurry, mixture of sand, mud and water.
3) Particular used in laying the pipes on the water used in dredger project.
