Top Quality Dredger Discharge UHMWPE Pipe

1. Excellent Wear Resistance:

Of all the pipe materials, UHMWPE pipes exhibit the smallest abrasion index. Of all the plastic pipes presently available,

the anti-abrasion performance of UHMWPE is 18 times higher than phenolic polymers, 6 times higher than polyamide polymers (PA66), 5 times higher than poly(tetrafluoroethylene) (PTFE) as well as being 6.6 times higher than carbon steel, 5.5 times higher than stainless steel and 27 times higher than copper, ideal for sand and slurry discharging;

2. Low surface roughness, Higher flow rate, Saving Pumping Costs

UHMWPE pipes have smooth interior surfaces which assure low friction loss and high flow rate. Because UHMWPE pipe do not rust, pit, scale, or corrode, the high flow rate continues for the life of the piping system. The internal roughness of UHMWPE pipe is only 0.0010 mm thus the pressure loss of UHMWPE pipe is about 1/10 of steel pipes resulting in an over 20% of increase in transfer efficiency.Since the internal wall of UHMWPE pipes is very smooth this practical prevents fouling or scale formation on the inner wall of the pipe and hence there is no drop in pumping efficiency

3. Minimized Maintenance time&Costs, Less Downtime, Less loss of production

The far superior wear resistance of UHMWPE pipe will significantly increase the time between pipe replacements and rotation, which will largely reduce:

a. reduced maintenance costs and time;

b. reduced downtime for maintenane and less loss of plant production time;

4. High strength, drurable material

UHMWPE pipes are highly resilient(Elongation reaches 500%), tough and durable products that have high-tensile strength (30Mpa) and high-impact strength(Notched Izod Impact strength reaches 166kj/m2). They can withstand high pressure for long periods. In this case, the UHMWPE pipes could withstand various impacts from sand and slurry;

5. Corrosion Resistance

With higher structure stability ,UHMWPE pipes are corrosive resistant to sea waters. No electro chemical corrosion, no need anti-corrosive coating;

6.Lightweight

UHMWPE pipes are lightweight – approximately one-half the weight of aluminum and one-eighth the weight of steel – reducing transportation, handling, and installation costs.

7.Easy Connection:

The UHMWPE pipelines could be connected by steel flanges, easy to install and dismantle at the working sites.

Furthermore, the UHMWPE pipe ends will be turned up to work as gaskets, the flat sealing face and good verticality will keep good sealing and well protect the flanging part not easy to be worn out.

Here are some main dredge projects in foreign countries:

1. Paraguay Asuncion Dredge projects since 2010;

2. Maldives Dredge projects

3. Tanzania Zanzibar port Dredge Projects

4. Phillippine Manila port Dredge projects

5. Malaysia Dredge projects

6. Indonesia Dredge Projects

The UHMWPE pipes 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.
