1. High Wear Resistant
Compare with existing plastic pipes, Wear resistant UNMWPE pipe has the most excellent wear resistance which is 4 to 7 times that of Q235 steel pipe and 2.7 times that of wear-resistant steel 16Mn. Therefore it increases pipe flow rate and improves the transmission efficiency of more than 20%. The working life of UHMWPE pipes is more than 3 times that of wear-resistant steel pipe. Wear resistant UHMWPE pipe has great advantages to replace traditional metal pipes in delivering abrasive media.
2. Impact Resistant
Wear resistant UHMWPE pipe is greatly impact resistant which is 5 times that of HDPE pipe, 2 times that of PC pipe and 10 times that of PTFE pipes.With extraordinary impact resistance，UHMWPE pipe can withstand great water hammer impact when starting up pump station.
3. Low Energy Consumption
Wear resistant UHMWPE pipe is self-lubrication and non-adhesive. Its coefficient of friction resistance is 0.009 while that of steel pipe is 0.013. With the same diameter, flow rate of UHMWPE pipe is larger than steel pipe, and with the same flow rate, UHMWPE pipe can save 25% energy.
4. Non-scaling
With roughness of 0.00022 and smooth pipe inner wall, it can efficiently avoid scaling without acid cleaning, which save a lot of maintenance cost.
5. High Flexibility
With high toughness and elongation of no less than 350%, the UHMWPE pipe and the connection site will not crack when crust settling which maximally ensures to supply water normally.
Advantage of UHMWPE pipe in dredging project:
UHMWPE pipe is high wear resistant. The flow rate of UHMWPE pipe is more than 4 times that of steel pipe i.e. working life of UHMWPE pipe is 4 times longer than that of steel pipe, which reduce times of changing pipes during the project and reduce maintenance cost. With low roughness, UHMWPE pipe can save 20% energy which reduces the operation cost. UHMWPE pipe is light in weight and flexible which reduce installation cost and increase comprehensive benefit.
