Opis izdelka

Ultra-high molecular weight polyethylene 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

HDPE 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

Med obstoječimi inženirskimi plastičnimi masami je vrednost udarne žilavosti polietilenske cevi z zelo visoko molekulsko maso največja in mnogi materiali bodo pri eksploziji resnih ali ponavljajočih se udarcev razpokali, zlomili ali utrudili površinsko napetost. Naši izdelki ne bodo poškodovani s preskusom konzolnega nosilca v skladu s standardi GB1843 in lahko nosijo močne zunanje vplive, notranje preobremenitve in nihanje tlaka.

3. Odpornost proti koroziji

Pe pipe 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. Dobro samopodmazovanje
PE 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

PE pipe has excellent surface non-adhesion and surface smoothness due to its small friction coefficient and non-polarity. 

7. Long life-span

Nenasičenih genov molekularne verige PE je manj, njegova odpornost proti utrujenosti je več kot 500 tisoč-krat in odpornost na razpoke v okolju več kot 4000 ur, kar je dvakrat več kot PE. Po pokopu in uporabi 50 let lahko še vedno ohranja več kot 70% mehanskih lastnosti.

8. Enostavna namestitev

The weight of unit length of PE pipe is only one-eighth of the steel pipe, which makes loading and unloading, transportation, installation be more convenient.
