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.
