Ultra-high molecular weight polyethylene (UHMW-PE) is developing very quickly , before the 1980s, the world's average annual growth rate of 8.5% , after the 1980s , the growth rate as high as 15 % to 20 %. Moreover, China's average annual growth rate of over 30 %. 1978 World consumption of 12,000 ~ 12,500 tons , while in 1990 the world demand of about 50,000 tons , of which the U.S. accounted for 70 %. 2007-2009, China has gradually become the world's plastics factory , super molecular weight polyethylene industrial development is very rapid .
Features ultra-high molecular weight polyethylene pipe
- High wear characteristics of ultrahigh molecular weight of up to 200 million or more , small abrasion index , 6.6 times higher than normal wear alloy . Greatly improve the life of the pipeline .
- High impact resistance , the products meet GB1843 standards , the impact toughness of the highest value of the product in an existing engineering plastics .
This product can be resistant to corrosion erosion harsh chemicals.
- Good self- lubricating self-lubricating well. Low coefficient of friction . Surface is not attached , no scaling .
- The unique low temperature resistance of this product is excellent low temperature performance , long-term work at a temperature of -50 ℃ to 80 ℃ .
- Excellent corrosion cracking resistance to environmental stress cracking resistance optimal resistance to environmental stress cracking > 4000h, is more than 2 times the PE100.
- Easy installation accounts for only one-eighth the weight of steel , making loading and unloading, either welded or flanged connections are available to install , safe, reliable, convenient , no corrosion, saving labor.
Applications
Bearing capacity of ultra high molecular weight polyethylene pipe , impact resistance , wear resistance , corrosion resistance, low temperature resistance and are exponentially increase self-lubricating , can be used for oil , coal , mining , water supply , electricity, chemical and other fields . Because of its excellent performance, security, reliability and reasonable price , the products will gradually replace metal pipes and other plastic pipe .
Economy
Price ultra high molecular weight polyethylene pipe , lower than conventional steel , coupled with a low friction coefficient , flow capacity , high impact strength, corrosion resistance , abrasion resistance, weather resistance , and many other factors contrast , its performance is far more than other plastics prices pipes and pipe.
