HDPE coal mining pipe
HDPE pipes for mining
HDPE pipes for mining are mainly used in coal mine underground for drainage, ventilation, coal slurry delivery, gas drainage and so on
Coal mine special pipe
Underground coal mine with ultra high molecular weight polyethylene pipe is modified ultra high molecular weight polyethylene as raw material, through special extruder extrusion. Ultra high molecular weight polyethylene (UHMWPE) is stuck in more than 1.5 million are molecular weight polyethylene linear structure, called "magic plastic", it focused almost all kinds of plastic, has the advantages of other plastic incomparable wear-resisting, impact resistance, self-lubricating resistance, corrosion resistance, low temperature, non-adhesive etc sum performance, it and ordinary mine polyethylene pipe, and various performance compared to all have the advantage, especially the impact strength is common polyethylene pipe of more than four times as much, but say "hit not bad, fall not broken, grinding not bad". Relative price is more reasonable.
Advantages:
1.Anti-abrasion: the abrasion value of UHMWPE pipe is 1/4 of steel pipe, 1/3 of HDPE pipe under same working conditions.
2. Water hammer resistance: UHMWPE pipes have strong enduring capability to the impacts from various sands, mud and slurries.
3. Corrosive resistance: Higher structure stability, corrosion resistant to various chemical mediators.
4. No electrochemical corrosion, no need anti-corrosive coating.
5. Self-lubrication: The roughness of UHMWPE is 0.00022mm.
6. The pressure loss of UHMWPE pipe is 1/10 of steel pipes, 1/7 of nylon pipes.
7. Non-scaling: the internal wall is very smooth, preventing the fouling on the wall and no influence to the production efficiency.
8. Light weight: the density of UHMWPE pipe is only 1/8 of steel pipe.
Applications
Mainly used in underground coal mine for drainage, ventilation, coal slurry delivery, gas drainage and so on.
