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.
Applications:
1.Used in dredging sand pipeline;
2.It can be used in dredger, dredging pipe etc. in the sea, lake or river;
3.Particular used in laying the pipes on the water used in dredger project.
Remarks:

2. The floaters under the size of O.D4m*L4m are all available.
