The Detailed characteristics of UHMW PE mine tailing pipe supplier
Anti-abrasion: Under the same instance, the bulk lost is only the 1/7 of steel piper .
Anti High-pressure:It is applicable under the press 0.2Mpa-4.0Mpa.
Anti-corrosion:Because the solid structure,it can anti-corrosion very well.
From Lubrication:The abrasion is the least among all the pipes materials .Under the same stance,the press lost is only the steel pipes1/10,and is only the nylon 1/7.
Non-scaling:The internal wall is so slippery that the medium cant deposit on it..
Light Weight:The density is the 1/8 of the steel.it's easy to convey and install.
Available to connection: It's welded by flange or hoop. And it's convey and install.
Anti-aging: There is anti-ultraviolet radiation material in the pipes, May use above for 50 years under the burning hot sunlight.
Health&Safety:This kind of pipe is innocuity.
Temperature-resistance:The pipe can be used from -70oC to 85oC.
Long life: Under the same instance, the used life is 7 times of the steel pipes .
