Advantages of Different Kinds floating dredging pipe

In nowadays, there are mainly four kinds floating dredging pipes, which is classified according to the pipe materials: 

1, steel floating dredging pipe; 2 HDPE floating dredging pipe; 3, UHMWPE floating dredging pipe; 4, Self floating dredging pipe. 

The following with the advantages and disadvantages of the different kinds floating dredging pipes: 

No.1 Steel Floating Dredging Pipes:

Advantages:1, Steel pipe price is competitive;

2, High pressure;

3, suitable for large, sharp, hard rocks.

Disadvantages: 1, Installation cost and Maintenance cost is high;

2, Friction cofficient 0.13~0.16;

3, Using life is short;

4, Its production process will effect pollution to the environment.

No.2 HDPE Floating Dredging Pipe:

Advantages: 1, HDPE pipe price is 1.5 times of steel pipe;

2, Light weight, anti-corrosion, save installation cost and maintenance cost.

3, Friction cofficient 0.011;

4, Suitable for fine sand;

5, Its production process is environment friendly.

Disadvantages: 1, HDPE pipe can not bear high pressure(range from 0.4~1.6Mpa);;

2, Not wear resistant enough for medium sand and coarse sand; Not robust enough for large, sharp, hard rocks.

No.3 UHMWPE Floating Dredging Pipe:

Advantages: 1, UHMWPE pipe price is 1.8 times of steel pipe;

2, Light weight, anti-corrosion, save installation cost and maintenance cost.

3, Friction cofficient 0.009;

4, Suitable for fine sand, medium sand,coarse sand. For fine and medium sand, in the same condition, UHMWPE pipe is 3~4 times wear resistant than HDPE pipe and 6~7 times wear resistant than steel pipe.

5,Its production process is environment friendly.

Disadvantages: 1, UHMWPE pipe can not bear high pressure(range from 0.4~2.0Mpa);

2, Not robust enought for transporting large, sharp, hard rocks;

No.4 Self floating pipe

Advantages: 1, Flexibility;

2, Wear resistant;

3, Easy installation;

Disadvantages: 1, Its price is 8~10 times of UHMWPE pipe.
