Popis produktu

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. Veľmi vysoká odolnosť proti nárazu

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. Odolnosť proti korózii

Pe fajka je druh štruktúry nasýtených molekúl, takže jej chemická stabilita je veľmi vysoká. Odoláva erózii silných chemických látok a nepodlieha korózii v iných lúhoch a kyselinách, okrem slabej kyseliny pri vysokej vonkajšej teplote.

4. Good self-lubrication
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. Jedinečná odolnosť voči nízkej teplote

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. Vytváranie špiny nie je ľahké

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

7. Long life-span

Nenasýtených génov molekulárneho reťazca PE je menej a jeho odolnosť proti únavovej pevnosti je viac ako 500 000-krát a odolnosť proti praskaniu v prostredí je viac ako 4 000 hodín, čo je dvakrát viac ako PE. Stále si môže zachovať viac ako 70% mechanických vlastností po tom, čo je zakopaný a používaný 50 rokov.

8. Easy installation

Hmotnosť jednotkovej dĺžky PE potrubia je iba jedna osmina oceľového potrubia, čo umožňuje pohodlnejšie nakladanie a vykladanie, prepravu a inštaláciu.
