HDPE pipes for dredging with pipe floaters

 

Introduction of HDPE Pipes

 

With good efficiency, reliable channel interface, aging resistance and corrosion, etc. High Density Polyethylene (HDPE) Solid Wall Pipe could be popularly used in Potable Water, Sewer, Mining and Gas applications. They have the following advantages:

 

Features:

 

The high impact strength of HDPE pipe compared with other plastic materials ensures a greater resistance to the rigours of pipe laying conditions.

 

Damage Resistance:

 

HDPE has low notch sensitivity, providing a high level of resistance to the effects of external damage, especially important for pipe bursting operations and others where there is a likelihood of such damage.

 

Abrasion Resistance:

 

HDPE pipes have excellent abrasion resistance providing long life in abrasive slurry applications. In most of these applications HDPE pipe outlasts other pipe materials such as mild steel and rubber lined steel.

 

Chemical Resistance:

 

Outstanding resistance to a wide range of chemical reagents allows the use of polyethylene systems in applications such as: Tailings pipelines and chemical treatment applications used in mining operations.

 

Flexibility:

 

HDPE pipes are flexible and can be bent to a minimum bending radius of 30 times the pipe’s outside diameter. This flexibility is critical in applications such as submarine pipe lines, mine subsidence and earthquake prone areas. This inherent resiliency and flexibility allows the pipe to absorb surge pressures, vibration and stresses cause by soil movement.

 

Ease of Installation:

 

HDPE pipe are easy to install with their light weight and long lengths. Polyethylene coiled pipes are widely used in applications such as stock watering, irrigation systems, communications, gas and reticulated water mains due to rapid installation and the ease and less frequent jointing.

 

High Flow Capacity

 

HDPE pipe has lower friction factors than most non-plastic materials. The surface energy characteristics of HDPE ensure that material deposition is inhibited and the smooth bore characteristic is maintained over the working life of the pipeline.

 

Long Life:

 

HDPE pipes have a proven high reliability record across a wide range of industries and applications, now approaching a period of 50 years. HDPE also provides a long maintenance free lifetime with low whole life costs, compared to many other materials.

 

Trenchless Construction:

 

HDPE pipes offer many advantages in slip lining, pipe bursting, directional drilling and microtunnelling including features such as long lengths, corrosion resistance, light weight and ease of installation with minimum disruption.

 

Applications

 

Good features of HDPE enable our HDPE pipe to be used for a diverse range of applications including:

l         Mining-above and below ground installations.

l         Slurry Lines-to convey suspended solid matter in quarries and mine.

l         Industrial and Chemical-to transport aggressive fluids.

l         Submerged Pipelines-for cable ducting, water and sewerage.

l         Water Supply.

l         Sewerage, Effluent and Waste Water.

l         Gas Distribution.

l         Trenchless Construction-for water supply, sewers and gas.
