UHMWPE sand dredging pipes
UHMWPE pipes are made of ultra high molecular weight polyethylene with a viscosity average molecular weight of 2.0 to 9.2 million g/mol.
We produce pipes using advanced extrusion technology. DRAGON UHMWPE
pipe is widely used in dredging, mining, chemical industry, power plant, water pipeline, food industry, transportation system, etc.
Diameter: ID 30 to ID 1200mm
Thickness: 3.5mm to 65mm
Length: 5.8m or 11.8m or customized length but suitable for transport layer is a basic requirement when designing thickness
Using UHMWPE Dredge Pipe:
1. Connect the UHMWPE dredge pipe to the float and rubber hose.
2. 3 pairs of floats are required for each 12 m of UHMWPE excavator pipe.
3. A rubber hose is connected to all three UHMWPE dredge tubes to absorb deformation caused by wind and waves.
