Ultra-high molecular weight polyethylene pipe (UHMWPE pipe) is widely used in metallurgical mines, electric power, petroleum, natural gas, textiles, paper making, food, chemica industry, machinery, electrical and other industries.
1. Extremely high wear resistance
UHMWPE pipe has 2 million or more molecular weight, the smallest wear index, which makes it have a very high capacity of anti-sliding friction. Its wear resistance is 6.6 times higher than normal alloy steel, 27.3 times that of stainless steel, 17.9 times that of phenolic resin, 6 times that of nylon 6, 4 times that of polyethylene, and it increases the life of the pipeline substantially.
2. Very high impact resistance
Of the existing engineering plastics, the value of the impact toughness of ultra-high molecular weight polyethylene pipe is the highest, and many materials will crack, break, split or surface stress fatigue in the explosion of serious or repeated impact. Our products will not damage by cantilever beam impact test according to GB1843 standards, and can bear strong external impacts, internal overload and pressure fluctuation.
3. Corrosion resistance
UHMWPE is a kind of structure of saturated molecules, so its chemical stability is very high. It can withstand the erosion of potent chemical substances, and it is not subject to corrosion in other lye and acid except for some mild acid at high temperature outside.
4. Good self-lubrication
UHMWPE pipe contain the waxy substance itself, and its self-lubrication is very good. The frictional coefficient (196n, 2 hours) is only 0.219mn/m (GB3960), so its self-lubrication is better than steel or brass with oil lubrication.
5. The unique resistance to low temperature
The resistance to low temperature of UHMWPE pipe is excellent, and its impact resistance and anti-abrasion can't change basically at minus 269 degrees celsius. It is the only available engineering plastics can work at temperatures close to absolute zero. Meanwhile, the adaptable temperature range of UHMWPE pipe is large, and it can be used within -269 to 80 degrees celsius.
6. Not easy to form dirt
UHMWPE pipe has excellent surface non-adhesion and surface smoothness due to its small friction coefficient and non-polarity.
7. Long life-span
The unsaturated genes of UHMWPE molecular chain are less, and its fatigue resistance strength is more than 500 thousand times, and its environmental stress cracking resistance is more than 4000h, which is twice more than the PE. It can still maintain more than 70% mechanical properties after it is buried and used for 50 years.
8. Easy installation
The weight of unit length of UHMWPE pipe is only one-eighth of the steel pipe, which makes loading and unloading, transportation, installation be more convenient.
9. Other characteristics
UHMWPE pipe can also absorb energy, absorb noise and resist static electricity, and holds shielding ability to the electron. It can't absorb water, and its specific weight is small. It is easy to do mechanical working, and can be colored.
