Dredge Pipes with Floats

UHMWPE Dredging Pipes with Floats:

Q: What's the difference between HDPE pipe and UHMWPE pipe?

A: the molecular wieght for HDPE pipe is only 30,000-50,000, however, the UHMWPE pipes is 3.5 million to 9.2 million. The higher molecular weight enables UHMWPE pipes to have a much better quality than HDPE pipes.

Q: What's the advantages of UHMWPE pipes compared with HDPE pipes?

A: a) Wear Resistance: the wear resistance of UHMWPE material is the top among engineering plastics, It is 10 times better than HDPE material;

b) Higher pressure bearing capability: with 2 times better of tensile strength than HDPE pipes, the UHMWPE pipes could bear higher working pressure. In this case, with the same internal diameter, the UHMWPE pipes could have thinner wall thickness to bear same working pressure.

Advantages of UHMWPE Pipes:

Longer Life

With a wear resistance 4 to 7 greater than Q235 Steel or 10 times that of HDPE (PE100) pipes under the same operating conditions, UHMWPE Pipe will give you far superior life under most operating conditions.

Lower Maintenance Costs, Less Maintenance Time, Less Downtime, Less Loss of Production

The far superior collaboration of wear resistance and weight reduction (0.93 SG) means the time between pipe replacements and/or rotations can be increased whilst simultaneously reducing installation management constraints of lifting gear and excavation requirements.

Reduced Pumping Costs

Along with the benefits mentioned above, UHMWPE Pipes also offer significant cost savings through increased pumping efficiency. With a surface roughness of 0.00022mm UHMWPE Pipe is extremely smooth and has resultant properties superior to PTFE (Teflon). Quantifying by example UHMWPE has a friction coefficient of 0.05, compared to 0.28 for HDPE or 0.58 for Steel (ISO 8295).

This means less friction, less pressure loss and greatly reduced energy inputs to deliver the same result.

Chemical and Corrosion Resistance

With chemical resistance second only to PTFE (Teflon), UHMWPE pipe will offer superior life to other pipeline products in acidic or corrosive applications under 85 degrees C.

Specications of UHMWPE pipes:

A) Dredging Industry: sea shore, sand suction, slurry dredge, river channel.

B) Mining Industry: mine powder, mine slurry, mine tailing, mine waste rock delivery

C) Sea engineering: sea water desalinization, dredging

D) Water Drainage: Sewage pipe

E) Chemical Industry: mud and corrosive medium with slag delivery

Gas & Oil Industry: Crud oil, petroleum and natural gas transport.
