Marine and Dredging Industry UHMWPE/HDPE Sand Mud Oil Floater Pipeline
UHMWPE Pipe
(Ultra High Molecular Weight Polyethylene Pipe)
As a newly-high-tech UHMWPE Pipes ,it almost has all kinds of merits of plastic,and is also an ideal wear-resistant materials, having been widely used in metallurgical works,chemical industry,electric power and many others field both in and broad.
The characteristic of UHMWPE pipes
Anti-abrasion: Under thesame instance, the bulk lost is only the 1/7 of steel piper .
Anti High-pressuer:Its applicableunder the press 0.2Mpa-4.0Mpa.
Anti-corrosion:Because thesolid structure,it can anti-corrosion very well.
From Lubrication:Theabrasionis the least among all the pipes materials .Under the samestance,the presslost is only the steel pipes 1/10,and is only the nylon1/7.
Non-scaling:The internal wall is soslippery that the medium cant deposit on it..
Light Weight:The density is the 1/8 of thesteel.it's easy to convey and install.
Available to connection: It's weldedby flange or hoop. And it's convey and install.
Anti-aging: There id anti-ultravioletradiation material in the pipes, May use above for 50 years under the burninghot sunlight.
Health&Safety:This kind ofpipe is innocuity.
Temperature-resistance:The pipe canbe used between -70oC--85oC.
Long life: Under the same instance, theused life is the steel pipes 7 times.
