UHMWPE dredging pipe
Wear resistant UHMWPE dredging pipe
DRAGON UHMWPE pipe is made from Ultra High Molecular Weight Polyethylene with viscosity-average molecular weight of 2.0 millioin to 9.2 million g/mol.
We manufacture the pipes with utilizing advanced extrusion technology.
DRAGON’s UHMWPE pipes have been widely applied in the fields of dredging, mining, chemical industry, power plant, water supply, food industry, conveyor systems, etc.
Diameter: ID 30 to ID 1200mm
Thickness: 3.5mm to 65mm
Length: 5.8m or 11.8m or customised length but suitable for transportation
For wear process, please inquire us to get right ID and thickness
Working pressure and required wear layer is basic requirement for thickness design
How to use UHMWPE dredging pipe：
1. Connect UHMWPE dredging pipe with floater and rubber pipe.
2. Every 12m UHMWPE dredging pipe needs 3pairs floaters for floating.
3. Every three UHMWPE dredging pipes connect one rubber hose for Buffer the distortion caused by wind and wave.
High wear resistance
The wear resistance is 3 to 7 times of Q235 steel pipe or PE100 pipe
Which means :Longer Working life, Less Maintainence cost and Less downtime for pipe replacement and rotation
Samples before wear test Samples after wear test
Four samples at the same size and same weight
Average wear loss of DRAGON Wear pipe is 16.8%
Average wear loss of PE 100 is 56.1%
Surface roughness of UHMWPE pipe is 0.00022mm superior to PTFE (Teflon).
UHMWPE has a friction coefficient of 0.05 compared to 0.28 for HDPE or 0.58 for steel (ISO 8295)
For its Exrtemely smooth surface, UHMWPe pipe has far superior anti scaling property to any other pipelines on the market curretly
Which means less friction loss, less pressure loss and greatly reduced energy inputs to deliver the same result.
Shiny Smooth Dragon Wear Pipe Random HDPE pipe
High impact strength, flexible and light
UHMWPE is 5 times of oridinary PE pipes, 4 times than HDPE, 2 times of polycarbonate pipe, and 10 times of PTFE pipe.
It means easy installation and less installation cost
High corrosion resistance
For its saturated molecular structure, it has high chemical stability, resistance to all kinds of corrosive medium (acid, alkali, salt) and organic solvent.
It will offer longer life than other pipelines in acid or corrosive applications.
Unique Australian Flanging Technology
We used our Australian partner's automated flanging technology.
It is unique in the UHMWPE world which results in significant performance benefits.
Consistent and better than everyone else flanging quality, Fast, safe and efficient production.
