UHMWPE dredger pipe for cutter suction dredger

1. Excellent wear resistance.

UHMWPE wear resistance ranks first all plastic material, 66 times than nylon, 4 times than

polytetrafluoroethylene, 9 times than ordinary polyethylene, even more than ordinary metals,

is 7 times than that of carbon steel, and 10 times than stainless steel, greatly improved the

service life.

2. Light weight. The density UHMWPE is about 0.94g / cm3, lower than other engineering

plastics, 1/2 lighter than polytetrafluoroethylene, 1/7 light of the steel pipe, thus easy for

installation, reducing the energy consumption.

3. Self-lubricating. The friction of UHMWPE is very low and good self-lubricating performance,

better than other metal pipelines.

4, Chemical resistance. UHMWPE has the high chemical stability and anti-corrosive ability in

the certain range of temperature and concentration ability of various of corrosive media

(acids, bases, salts) and organic media.

5. Lower water absorption. UHMWPE is almost non-absorbent, does not swell in water, much

less absorbent than nylon.

6. Non-stick performance. The UHMWPE surface is very weak, almost equal to PTFE, thus

no scale deposit at the pipe surface.

7. Excellent impact resistance. UHMWPE has the superb impact resistance, 2 times better

than polycarbonate. Even in the ammonia temperature (-269 ℃), it can still maintain good

impact resistance, which make it a wide application in cryogenic engineering field.

8. Good sanitation. UHMWPE meet the national health standard, even up to the standard

of human-contact field.

In addition, UHMWPE also has excellent ability of cracking-resistance, electrical insulation-

resistance, fatigue-resistance, deformation-resistance under high temperature,

γ-rays-resistance and other superb characteristics.
