UHMWPE Pipe Properties:

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.  .

Application advantages of wear resistant UHMWPE pipes

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.

Advantage of UHMWPE pipe in mining and metallurgy

Coke, mining powder, pulp and slag from mining and metallurgy is quite abrasive to pipelines. Traditional steel pipe can only use for 6 or 12 months for transmission of above media and need to turn 90 degrees every half year. Meantime, UHMWPE pipe has extraordinary wear resistance which greatly reduces damage of pipes from abrasion and its working life is more than 4 times that of traditional steel pipe. With good impact resistance and high flexibility, UHMWPE pipe can withstand impact from external force and diastrophism. Wear resistant UHMWPE pipe is better alternative as transmission pipe for mining and metallurgy.

Advantage of UHMWPE pipe in transmission of coal ash in thermal power plant

For hydraulic ash-sluicing system of thermal power plant, the problem of scaling in inner pipe wall is quite prevalent,especially within 100 meters of the entrance, scaling and corrosion are more serious. Ash-sluicing pipe is seriously worn besides scaling. Within two years there will be serious leakage especially at the bend sites. Wear resistant UHMWPE pipe is self-lubricating and non scaling. With excellent wear resistance and corrosion resistance, it has longer working life and significantly save maintenance costs which greatly increases benefits.

Advantage of UHMWPE pipe in pneumatic transmission

With low friction resistance, high self lubrication and high wear resistance, UHMWPE pipe can be widely used in field of pneumatic transmission of material which effectively reducing abrasion and corrosion and lowering energy consumption.
