Large Diameter UHMWPE Dredging Pipe

Description

 Q: What's the difference between HDPE pipe and UHMWPE pipe?
 
A: the molecular wieght for HDPE pipe is only *0,*****0,**0, 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 *0 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.
 

Longer Life
 
 With a wear resistance 4 to 7 greater than Q**5 Steel or *0 times that of HDPE (PE**0) 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.*3 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.****2mm UHMWPE Pipe is extremely smooth and has resultant properties superior to PTFE (Teflon). Quantifying by example UHMWPE has a friction coefficient of 0.*5, compared to 0.*8 for HDPE or 0.*8 for Steel (ISO ***5).
 
 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 *5 degrees C.
