3.5 Mpa Steel-PE pipeline in coal mining
 

 Application:

"Donghong" PE pipes for mining are mainly used in underground coal mine for drainage, ventilation, coal slurry delivery, gas drainage and so on.

Quality assurance:

Donghong Brand steel reinforced PE mining pipe has good physical property and long-term hydrostatic strength. It is the first to get the certificate of 3.5Mpa Coal Mining Safety Mark of China. Its service life can reach over 50 years.

Carried standard: 

CJ/T189—2007, Q/DHSY01-2008

Performance and characteristics:

1. Light weight, long service life, easy installation

Its weight is lighter, while its service life is 8-10 times more than steel pipe.

2. Good anti-corrosion property, high pressure resistance, superior mechanical property.

Steel wire plastic composite pipe in coal mining has great corrosion resistance, superior mechanical property. The strength, rigid, impact and high pressure resistance performance is better than that of plastic pipe. It is widely used in piping project under different conditions.

3. Low noise in media transportation.

Smooth surface, low resistance of fluids, low noise.

4. Good sealing.

No leakage after pressure testing.

5. Easy installation

Patented pipe fittings are developed on our own. They are convenient to install and need no anti-corrosion treatment or welding work, which can reduce installation difficulty and save lots of working expenses under complex or special environment. Comprehensive economic efficiency of SSPE pipe is 8-15 times more than that of steel pipe.

6. Excellent flame-resisting and antistatic performance

Both fire resistant and antistatic performances meet the national standard.  It can be used in inflammable and explosive dangerous place.
