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. UHMWPE can be used in the concentrated hydrochloric acid with less than 80% concentration, and its performance is quite stable in the sulfuric acid with less than 75% concentration and in the nitric acid with less than 20% concentration.

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. Especially its dry lubrication can be fully displayed in the poor environment and places of more dust and sand. It not only can be used freely, and can protect the workpiece from wearing or strain.

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. Existing materials form dirt usually in the medium with PH value of 9 or above, but UHMWPE pipe can’t form dirt. This characteristic has great significance to the system of discharging powder and coal ash of power plant, and is also well suited for the pipeline of crude oil, mud and so on.

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, and can reduce workers’ labor intensity. Anti-aging properties of UHMWPE pipe are very strong, and it is not easy to get aging within 50 years, regardless of setting up on the ground, or being covered underground. It is possible whether it is welded or connected by flange when install. Safety, reliability, swiftness, convenience, no anti-corrosion and labor-saving effort all fully show the superiority of "energy conservation, environmental protection, economy, efficiency" of UHMWPE pipe.
