Detailed Description
Steel-HDPE coal mining pipe and fittings
1. Pressure (0.8-3.5Mpa)
2. Fire resistant & antistatic
3. For use in underground coal mine
Product introduction:
Using High Density Polyethylene (HDPE) as the material for the framework, strong steel wires are spirally twisted around the framework to create a high tensile strength to strengthen the body.
It is made up of five layers, two layers of HDPE both inside and outside, steel wire in the middle and double layers of hot melt adhesive to get both layers of the HDPE with the steel wire together.
Application:
It’s mainly used in coal mining. This product falls into coal-mine use water pipes, coal-mine use air pipes, coal-mine use guniting pipes and coal-mine use gas drainage pipes, etc.
Apprearance:
outside surface smooth; no bubbles, scratches, uneven colors
Specifications:
Appearance: black or any other color on request
Nominal Pressure:0.8-3.5Mpa
Nominal diameter:50-630mm
Nominal wall thickness:4.5-23mm
Quality assurance:
Donghong Brand steel wire reinforced PE composite pipe in coal mining 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:
(1) CJ/T189—2007 (our national industry standard)
(2) Q/DHSY01-2008 (our enterprise standard)
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 property.
No Geakage 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 flame-resisting and antistatic performances meet the national standard. It can be used in inflammable and explosive dangerous place.
