钢高密度聚乙烯的综合烟煤矿

Steel HDPE composite pipe for coal mining Product introduction 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. Product quality conforms to our enterprise standard Q/DHSY01-2008. Apprearance: outside surface smooth; no bubbles, scratches, uneven colors Specifications: Appearance: black or any color as you required Nominal Pressure:0.8-5.0Mpa 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. 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 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. The pipe not only combines the advantages of plastic and steel pipes but also eliminates their disadvantages such as lower pressure resistance for plastic pipe and antirotless for steel pipe. With its excellent flexibility the pipe is suitable for water and gas supply for underground usage in long distance. Up to date the pipe is the prefered products to replace traditional pipe like steel pipe etc. If you are interested in our products or would like to know more about our company, please feel free to contactme directly for details.
