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.

Non-Scaling

Because of its very smooth surface and self-lubricating properties, UHMWPE Pipe has far superior anti-scaling properties to any other pipeline on the market today. A non-stick factor that leads to its strength in the marine industry, preventing barnacle formation.

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.

Lower Installation Costs

The strength of UHMWPE pipes can offer many savings in installation costs:

• High compressive strength means reduced size or eliminating excavations (greater than 1.5x that of HDPE)
• Combination of strength and flexibility (>250% tensile elongation) means concrete bases are not required on wetlands and difficult terrain
• High strength and flexibility provides greater protection against damage due to ground subsidence, earthquakes or other unexpected movement and loading of the pipeline
• Can be laid directly on the seabed

• Performance comparison of UHMW-PE pipe for dredging with other materials

What is UHMWPE?

   Ultra-high molecular weight polyethylene (UHMWPE) is a new kind of engineering thermoplastics with more than 3 million viscosity-average molecular weight. Ultra-high molecular weight polyethylene pipe has superior performance over conventional HDPE pipe such as much high wear resistance, impact resistance, excellent resistance to internal pressure strength, resistance to environmental stress cracking, intrinsically self-lubricating, anti-adhesion, low temperature resistance and excellent chemical resistance.   

Molecular Weight Comparison between UHMWPE&HDPE: The higher molecular weight, the better wear resistance .
