Sand Dredging Pipelines Petroleum Transport UHMWPE Pipes
Advantage:
Our HDPE water supply and drain pipes are manufactured for excellent performance and long life.
• Its butt joints eliminate potential leak points, common with ductile iron 10 to 20 feet long, with a zero leak rate.
• Highly resistant to corrosion and weathering, recent studies conclude that it will last at least 50 years.
• Lightweight and flexible for easy installation, eliminating the need for accessories when changing orientation and making it ideal for use in earthquake-prone areas.
• High strength walls give it the highest PE pressure levels, excellent resistance to SCG and increased resistance to rapid crack growth.
• The labor stress level of high performance PE plastic makes it a superior choice over ductile iron or steel pipes, especially for large diameter pipes.

Lower Coefficient of Friction
The UHMWPE material is regarded as the ideal cost/performance abrasive resistant material in the tribology field. With good friction coefficient of 0.07-0.11, and good self lubrication, the UHMWPE material will be difficult to have sea growth.
| Material | No Lubrication | Water Lubrication | Oil Lubrication |
| UHMWPE | 0.1-0.22 | 0.05-0.1 | 0.05-0.08 |
| PTFE | 0.04-0.25 | 0.04-0.08 | 0.04-0.05 |
| POM | 0.15-0.35 | 0.1-0.20 | 0.05-0.10 |
