Product Description

 

 

Product Description

The shell of PE floater is made from medium density polyethylene material, has very good flexibility.Dredging floats are composed of two empty half shells and can be filled with closed cell PU foam. They are connected to the pipe by galvanized bolts, nuts and flat washer.  It is filled with high-strength polyurethane foam.

PE Floats are generally moulded by a high wear resistant PE. The design is set up to achieve a strong but flexible float. Many different types of ring floats are available to suit requested application. The floater has good property of impact resistance, waves resistance, reasonable structure, easy assemble,very popular as floating material of dredging.With reasonable becomes the ideal substitution of the traditional steel floater for thr floating dredging pipes.

 

 

The hull of dredging floaters are made from PE material with good flexibility, and it is filled with high density polyurethane foam inside. With reasonable structure and good performances, the polyethylene dredging floaters are ideal to replace the steel pontoons for the floating discharging pipe.

1. Good flexibility and excellent impact resistance, particularly suitable for the installation in the sea;

2. Light weight, easy for installation and handling, with lower costs for transportation;

3. Corrosive Resistance with longer working life, it could work 3 times longer than steel pontoons.

4. The costs and performances are more economical than steel pontoons.

5. Usually, 2 pieces of floaters are worked for 1 pair, 2 pairs for floaters are worked for 1 group, 1 group floaters could float 6-meter-long steel pipe and 1.5-meter-long rubber hose.

Product Introduction

MDPE floater is made of excellent flesibility of medium density polyethlene material,inside of shell is filled with high strength polyurethance foam.

Advantages

Good flexibility

Good flexibility, and excellent impact resistance, particularly suitable for the installation in the sea.

 

Light weight

Light weight, easy for installation and movement, with much lower transportation costs.


 

 

Corrosive Resistance

Corrosive Resistance, longer working life, it could work 3 times longer than steel pontoons.

a)Good toughness and environmental stress cracking resistance to suit working in the sea and lake.

 

b)Good property of low weight and wear resistance to suit to be assembled and carried.

 

c)Good property of corrosion resisting , weather fastness, longer life( 3 times longer than steel floaters).

 

d)Assembling is very simple, rapid and flexible.

 

e)Built in UV Inhibitors reduce fading caused by sunlight.

 

f)It can be used from -60 to 80°C.

 

1.       Application:

•  Used in river, channel sea, dam, and port for mineral pipe to float on water.
• For easy inspection of the dredging pipe.
•  Orange color is conspicuous, can be caution remark, in case of pipeline impact.
•  Widely used in sand mining, dredging, estuary clearance, beach replenishment or large land reclamation and other civil engineering projects.
• 
  
  
   

2.       Performance.

• Customized size is acceptable.
• Surface hull is made of MDPE; inside is full of high strength PU foam, rational construction, and excellent performance, can work under the surrounding degree between -60ºC ~ 80ºC
•  Light weights, eas y and convenient assembly, carry.
•  Big buoyancy, with high bearing capacity, is table and durable
•  Impact resistance, acid and alkali resistance, less water absorption, Free from seawater, chemicals, oil stains and aquatic organisms, no pollution, no damage to the environment
•  Long life, except strong natural force and artificial improper use, do not need to spend any maintenance, maintenance costs.
• Tolerance: Length tolerance: 1.5%, Diameter tolerance:±1%;Thickness tolerance: ± 2 mm,  Wight tolerance: ± 2%.
• The floater crust surface is smooth and uniformity, with vibrant concepts, the focal spot diameter is no more than 100mm;
• Features of floater crust and core:
•
