Ultra-high Molecular Weight Polyethylene(UHMWPE),which refers to the molecular weight of more than 2.5 mi-llion(The common polyethylene product is about 2-30 milli-on),has the development priority from the National Ministryof Science and Technology.High molecular weight gives itexceptional performance,is a comprehensive engineering best performance,its wear and impact resistance,corrosionresistance,self-lubricating,impact energy-the five propert-Ies is the best of the existing plastics,internationally knownas the"very magical material."
Characteristics:
1.Excellent wear resistance.UHMWPE wear resistance ranks first all plastic material,66 times than nylon,4 times than polytetrafluoroethylene,9 times than ordinary polyethylene,even more than ordinary metals,is 7 times than that of carbon steel,and 10 times than stainless steel,greatly improved the service life.
2.Light weight.The density UHMWPE is about 0.94g/cm3,lower than other engineering plastics,1/2 lighter than polytetrafluoroethylene,1/7 light of the steel pipe,thus easy for installation,reducing the energy consumption.
3.Self-lubricating.The friction of UHMWPE is very low and good self-lubricating performance,better than other metal pipelines.
4,Chemical resistance.UHMWPE has the high chemical stability and anti-corrosive ability in the certain range of temperature and concentration ability of various of corrosive media(acids,bases,salts)and organic media.
5.Lower water absorption.UHMWPE is almost non-absorbent,does not swell in water,much less absorbent than nylon.
6.Non-stick performance.The UHMWPE surface is very weak,almost equal to PTFE,thus no scale deposit at the pipe surface.
7.Excellent impact resistance.UHMWPE has the superb impact resistance,2 times better than polycarbonate.Even in the ammonia temperature(-269℃),it can still maintain good impact resistance,which make it a wide application in cryogenic engineering field.
8.Good sanitation.UHMWPE meet the national health standard,even up to the standard of human-contact field.In addition,UHMWPE also has excellent ability of cracking-resistance,electrical insulation-resistance,fatigue-resistance,deformation-resistance under high temperature,γ-rays-resistance and other superb characteristics.
Currently,our company offer various size of UHMWPE pipes,and wear-resistant UHMWPE composite steel pipe,ranging from Dia.60mm to 800mm,mainly used in transmission pipelines,such as transportation for mine tailings/ore,dredging work,processing piping,slurry,desalination,cryogenic media and crude oil transportation
