UHMWPE Slurry Pipe
UHMWPE Slurry pipe
What is UHMWPE
ultra high molecular weight polyethylene (UHMWPE) is a linear polyethylene with molecular weight of over2.5X 10^6 g/mol, which is approximately ten times that of high density polyethylene resins (HDPE). The extremely high molecular weight of this resin offers superior performance of UHMWPE to any other thermal engineering plastic.
UHMWPE Pipe can be used as slurry pipe, mine tailing pipe, dredge pipe, wear resistance pipe, mine tailing slurry pipe, sand and mud slurry pipe, coal mine pipe.
Advantage of UHMWPE pipe
- ultra high wear resistance
- ultra impact resistance
- ultra corrosion resistance
- excellent self-lubrication
- long life-span
- easy installation
- cost effective
UHMWPE mining pipe
Properties of UHMWPE pipe for mining
- High Wear Resistance
UHMWPE has the best wear resistant among all the engineering plastics. The higher molecular weight of the material is the more wear resistant of the UHMWPE pipeis. UHMWPE pipes are 4 to 7 times more wear resistant than PE 100 or Q235 carbon steel, 2.7times of SiMn 13 steel.Thus offers UHMWPE pipe longer life, less maintenance cost and downtime loss.
- High impact strength, flexible and light
The impact resistance of UHMWPE pipes is 5 times that of HDPE pipe, 2 times that of PC pipe and 10 times that of PTFE pipes.
It means easy installation and less installation cost
Extremely smooth/ Non scaling / less pumping cost
UHMWPE pipes have very smooth surfaces with low friction loss and high flow rate.
Surface g roughness of UHMWPE pipe is 0.00022mm, which provides UHMWPE Pipe far superior anti-scaling properties to any other pipeline on the market today. It saved maintenance cost of acid cleaning pipes.
UHMWPE has a friction coefficient of 0.05, compared to 0.28 for HDPE or 0.58 for Steel (ISO8295). Along with the benefits mentioned above, UHMWPE Pipes also offer significant cost savings through increased pumping efficiency.
It means less friction loss, less pressure loss and greatly reduced energy inputs.
High corrosion resistance
For its saturated molecular structure, it has high chemical stability, resistance to all kinds of corrosive medium (acid, alkali, salt) and organic solvent. It will offer longer life than other pipelines in acid or corrosive applications.
- Working temperature
-269 Degrees C to 85 degrees C.
- Environmental friendly
- UHMWPE is colorless, odorless and non-toxic. UHMWPE pipe is extruded out from pure virgin UHMWPE unless some additives required by clients.
