20" Cutter Suction Dredger matched HDPE pipes for sand/slurry discharging Advantages:

1. Excellent Wear Resistance:

UHMWPE material is regarded as ideal cost/performance abrasive resistant material in the tribology field. With extremely lower friction coeffient of 0.07-0.11, and good self lubrication, which enables the pipes to have good wear resistance;

2. Minimized Maintenance 

With good properties of wear resistance,corrosive resistance,low temperature resistance, the UHMWPE pipelines will not need the daily maintenance of anti-rust,anti freeze,scaling cleaning,etc, which could save 95% costs for maintenance during the operation.

3. Saving Pumping Costs

with good self lubrication and non-adhesion, the UHMWPE pipes have coefficient of friction of 0.0065,meanwhile, the steel pipe is 0.013. Therefore, the flow capacity of UHMWPE pipes is more than steelpipes. Under same flow rate, the UHMWPE pipes could save 20% fuel for the dredgers.

Production Flow

20" Cutter Suction Dredger matched HDPE pipes for sand/slurry discharging are continually extruded by special extruders and moulds. Here is the brief introduction of UHMWPE pipe production:

1. The UHMWPE powder will be melted together with a small amount of paraffin, carbon black in high temperature

2. Different pipes with different diameter and wall thickness will need to make different moulds.

3. the length of the UHMWPE pipes could be cut according to customers requirements

4. The color of UHMWPE pipes is the original color of the raw material, and it is specially processed during production.

Packing & Delivery

Polywood Packaging

For a small amount goods that need to be delivered by LCL,  polywood packaging is applied to protect the goods from scratching and damaging.

Wood Pallet

The other packaging method for LCL goods is wood pallet. The surface of the goods will be packaged with bubble plastic, the connection parts will be packaged with poly wood. 

Plywood flange at the end for each pipe in 40' GP or 20' GP FCL
