4.Non-scaling

CHARACTERISTIC OF UHMWPE dredging pipe

Anti-abrasion:the abrasion value of UHMWPE pipe is 1/4 of steel pipe,1/3 of HDPE pipe under same working condition.

Water hammer resistance:UHMWPE pipes have strong enduring capability to the impacts from various sands,mud and slurries.

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

Self-lubrication:The roughness of UHMWPE pipe is 0.00022mm.The pressure loss of UHMWPE pipe is 1/10 of steel pipes ,1/7 of nylon pipes.Over 20% of transfer efficiency will be increased.

Non-scaling:The internal wall is very smooth,preventing the fouling on the wall and no influence to the production efficiency.

Light weight:The density of UHMWPE pipe is only 1/8 of steel pipe.It is easy to move and install,especially suitable for the working sites at he lifting machines could not work.

Easy connection:flanges are available to connect the pipes,no need washers .The installation will be very easy and fast.

Anti-aging:the UHMWPE pipes will not be aging in 50 years under hot sunlight,and it could work over 100 years if buried underground.

Environment friendly: UHMWPE pipe is nontoxic,no bacteria,and no pollution to environment.

Low carbon:the discharge of carbon dioxide during UHMWPE pipe production is only 15% of steel pipe production.
