Product Description

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

Maidir leis na plaistigh innealtóireachta atá ann cheana féin, is é luach an diúltacht tionchair atá ag píopa polaitiléin ard-ard meáchan móilíneach ná an líon is airde, agus déanfaidh go leor ábhair craiceann, briseadh, scoilt nó tuirse ar strus dromchla sa phléascadh ar thionchar tromchúiseach nó arís agus arís eile. Ní dhéanfaidh ár dtáirgí damáiste do thástáil tionchair beam cantilever de réir caighdeáin GB1843, agus is féidir tionchar láidir seachtrach a bheith aige, ró-ualach inmheánach agus luaineacht brú.

3. Corrosion resistance

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. 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. 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

Tá neamh-greamaitheacht dromchla agus maolú dromchla den scoth ag píopa Corpoideachais mar gheall ar a chomhéifeacht cuimilte beag agus neamh-pholaitíochta.

7. Long life-span

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